Inheritance diagram for wxWindow:

Detailed Description

wxWindow is the base class for all windows and represents any visible object on screen.

All controls, top level windows and so on are windows. Sizers and device contexts are not, however, as they don't appear on screen themselves.

Please note that all children of the window will be deleted automatically by the destructor before the window itself is deleted which means that you don't have to worry about deleting them manually. Please see the window deletion overview for more information.

Also note that in this, and many others, wxWidgets classes some GetXXX() methods may be overloaded (as, for example, wxWindow::GetSize or wxWindow::GetClientSize). In this case, the overloads are non-virtual because having multiple virtual functions with the same name results in a virtual function name hiding at the derived class level (in English, this means that the derived class has to override all overloaded variants if it overrides any of them). To allow overriding them in the derived class, wxWidgets uses a unique protected virtual DoGetXXX() method and all GetXXX() ones are forwarded to it, so overriding the former changes the behaviour of the latter.

Styles

This class supports the following styles:

wxBORDER_DEFAULT:
The window class will decide the kind of border to show, if any.
wxBORDER_SIMPLE:
Displays a thin border around the window. wxSIMPLE_BORDER is the old name for this style.
wxBORDER_SUNKEN:
Displays a sunken border. wxSUNKEN_BORDER is the old name for this style.
wxBORDER_RAISED:
Displays a raised border. wxRAISED_BORDER is the old name for this style.
wxBORDER_STATIC:
Displays a border suitable for a static control. wxSTATIC_BORDER is the old name for this style. Windows only.
wxBORDER_THEME:
Displays a native border suitable for a control, on the current platform. On Windows XP or Vista, this will be a themed border; on most other platforms a sunken border will be used. For more information for themed borders on Windows, please see Themed borders on Windows.
wxBORDER_NONE:
Displays no border, overriding the default border style for the window. wxNO_BORDER is the old name for this style.
wxBORDER_DOUBLE:
This style is obsolete and should not be used.
wxTRANSPARENT_WINDOW:
The window is transparent, that is, it will not receive paint events. Windows only.
wxTAB_TRAVERSAL:
Use this to enable tab traversal for non-dialog windows.
wxWANTS_CHARS:
Use this to indicate that the window wants to get all char/key events for all keys - even for keys like TAB or ENTER which are usually used for dialog navigation and which wouldn't be generated without this style. If you need to use this style in order to get the arrows or etc., but would still like to have normal keyboard navigation take place, you should call Navigate in response to the key events for Tab and Shift-Tab.
wxNO_FULL_REPAINT_ON_RESIZE:
On Windows, this style used to disable repainting the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete and no longer has an effect.
wxVSCROLL:
Use this style to enable a vertical scrollbar. Notice that this style cannot be used with native controls which don't support scrollbars nor with top-level windows in most ports.
wxHSCROLL:
Use this style to enable a horizontal scrollbar. The same limitations as for wxVSCROLL apply to this style.
wxALWAYS_SHOW_SB:
If a window has scrollbars, disable them instead of hiding them when they are not needed (i.e. when the size of the window is big enough to not require the scrollbars to navigate it). This style is currently implemented for wxMSW, wxGTK and wxUniversal and does nothing on the other platforms.
wxCLIP_CHILDREN:
Use this style to eliminate flicker caused by the background being repainted, then children being painted over them. Windows only.
wxFULL_REPAINT_ON_RESIZE:
Use this style to force a complete redraw of the window whenever it is resized instead of redrawing just the part of the window affected by resizing. Note that this was the behaviour by default before 2.5.1 release and that if you experience redraw problems with code which previously used to work you may want to try this. Currently this style applies on GTK+ 2 and Windows only, and full repainting is always done on other platforms.

Extra styles

This class supports the following extra styles:

wxWS_EX_VALIDATE_RECURSIVELY:
By default, wxWindow::Validate(), wxWindow::TransferDataTo() and wxWindow::TransferDataFromWindow() only work on direct children of the window (compatible behaviour). Set this flag to make them recursively descend into all subwindows.
wxWS_EX_BLOCK_EVENTS:
wxCommandEvents and the objects of the derived classes are forwarded to the parent window and so on recursively by default. Using this flag for the given window allows to block this propagation at this window, i.e. prevent the events from being propagated further upwards. Dialogs have this flag on by default for the reasons explained in the Events and Event Handling.
wxWS_EX_TRANSIENT:
Don't use this window as an implicit parent for the other windows: this must be used with transient windows as otherwise there is the risk of creating a dialog/frame with this window as a parent, which would lead to a crash if the parent were destroyed before the child.
wxWS_EX_CONTEXTHELP:
Under Windows, puts a query button on the caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send a wxEVT_HELP event if the user clicked on an application window. This style cannot be used (because of the underlying native behaviour) together with wxMAXIMIZE_BOX or wxMINIMIZE_BOX, so these two styles are automatically turned off if this one is used.
wxWS_EX_PROCESS_IDLE:
This window should always process idle events, even if the mode set by wxIdleEvent::SetMode is wxIDLE_PROCESS_SPECIFIED.
wxWS_EX_PROCESS_UI_UPDATES:
This window should always process UI update events, even if the mode set by wxUpdateUIEvent::SetMode is wxUPDATE_UI_PROCESS_SPECIFIED.

Constructor & Destructor Documentation

wxWindow::wxWindow ( )

Default constructor.

wxWindow::wxWindow	(	wxWindow *	parent,
		wxWindowID	id,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `0`,
		const wxString &	name = `wxPanelNameStr`
	)

Constructs a window, which can be a child of a frame, dialog or any other non-control window.

Parameters:

parent	Pointer to a parent window.
id	Window identifier. If wxID_ANY, will automatically create an identifier.
pos	Window position. wxDefaultPosition indicates that wxWidgets should generate a default position for the window. If using the wxWindow class directly, supply an actual position.
size	Window size. wxDefaultSize indicates that wxWidgets should generate a default size for the window. If no suitable size can be found, the window will be sized to 20x20 pixels so that the window is visible but obviously not correctly sized.
style	Window style. For generic window styles, please see wxWindow.
name	Window name.

virtual wxWindow::~wxWindow ( ) [virtual]

Destructor.

Deletes all sub-windows, then deletes itself. Instead of using the delete operator explicitly, you should normally use Destroy() so that wxWidgets can delete a window only when it is safe to do so, in idle time.

参照:: Window Deletion Overview, Destroy(), wxCloseEvent

Member Function Documentation

virtual bool wxWindow::AcceptsFocus ( ) const [virtual]

This method may be overridden in the derived classes to return false to indicate that this control doesn't accept input at all (i.e.

behaves like e.g. wxStaticText) and so doesn't need focus.

参照:: AcceptsFocusFromKeyboard()

Reimplemented in wxPanel.

virtual bool wxWindow::AcceptsFocusFromKeyboard ( ) const [virtual]

This method may be overridden in the derived classes to return false to indicate that while this control can, in principle, have focus if the user clicks it with the mouse, it shouldn't be included in the TAB traversal chain when using the keyboard.

virtual bool wxWindow::AcceptsFocusRecursively ( ) const [virtual]

Overridden to indicate whether this window or one of its children accepts focus.

Usually it's the same as AcceptsFocus() but is overridden for container windows.

virtual void wxWindow::AddChild ( wxWindow * child ) [virtual]

Adds a child window.

This is called automatically by window creation functions so should not be required by the application programmer. Notice that this function is mostly internal to wxWidgets and shouldn't be called by the user code.

Parameters:

child Child window to add.

virtual void wxWindow::AddPendingEvent ( const wxEvent & event ) [protected, virtual]

See ProcessEvent() for more info about why you shouldn't use this function and the reason for making this function protected in wxWindow.

Reimplemented from wxEvtHandler.

virtual void wxWindow::AlwaysShowScrollbars	(	bool	hflag = `true`,
		bool	vflag = `true`
	)		`[virtual]`

Call this function to force one or both scrollbars to be always shown, even if the window is big enough to show its entire contents without scrolling.

Since:: 2.9.0

Parameters:

hflag	Whether the horizontal scroll bar should always be visible.
vflag	Whether the vertical scroll bar should always be visible.

注意:: This function is currently only implemented under Mac/Carbon.

void wxWindow::CacheBestSize ( const wxSize & size ) const

Sets the cached best size value.

参照:: GetBestSize()

bool wxWindow::CanScroll ( int orient ) const

Returns true if this window can have a scroll bar in this orientation.

Parameters:

orient Orientation to check, either wxHORIZONTAL or wxVERTICAL.

Since:: 2.9.1

virtual bool wxWindow::CanSetTransparent ( ) [virtual]

Returns true if the system supports transparent windows and calling SetTransparent() may succeed.

If this function returns false, transparent windows are definitely not supported by the current system.

Reimplemented in wxTopLevelWindow.

void wxWindow::CaptureMouse ( )

Directs all mouse input to this window.

Call ReleaseMouse() to release the capture.

Note that wxWidgets maintains the stack of windows having captured the mouse and when the mouse is released the capture returns to the window which had had captured it previously and it is only really released if there were no previous window. In particular, this means that you must release the mouse as many times as you capture it, unless the window receives the wxMouseCaptureLostEvent event.

Any application which captures the mouse in the beginning of some operation must handle wxMouseCaptureLostEvent and cancel this operation when it receives the event. The event handler must not recapture mouse.

参照:: ReleaseMouse(), wxMouseCaptureLostEvent

void wxWindow::Center ( int dir = wxBOTH )

A synonym for Centre().

void wxWindow::CenterOnParent ( int dir = wxBOTH )

A synonym for CentreOnParent().

void wxWindow::Centre ( int direction = wxBOTH )

Centres the window.

Parameters:

direction Specifies the direction for the centring. May be wxHORIZONTAL, wxVERTICAL or wxBOTH. It may also include the wxCENTRE_ON_SCREEN flag if you want to centre the window on the entire screen and not on its parent window.

注意:: If the window is a top level one (i.e. doesn't have a parent), it will be centred relative to the screen anyhow.

参照:: Center()

Reimplemented in wxDialog, and wxFrame.

void wxWindow::CentreOnParent ( int direction = wxBOTH )

Centres the window on its parent.

This is a more readable synonym for Centre().

Parameters:

direction Specifies the direction for the centring. May be wxHORIZONTAL, wxVERTICAL or wxBOTH.

注意:: This methods provides for a way to centre top level windows over their parents instead of the entire screen. If there is no parent or if the window is not a top level window, then behaviour is the same as Centre().

参照:: wxTopLevelWindow::CentreOnScreen

virtual void wxWindow::ClearBackground ( ) [virtual]

Clears the window by filling it with the current background colour.

Does not cause an erase background event to be generated.

Notice that this uses wxClientDC to draw on the window and the results of doing it while also drawing on wxPaintDC for this window are undefined. Hence this method shouldn't be used from EVT_PAINT handlers, just use wxDC::Clear() on the wxPaintDC you already use there instead.

void wxWindow::ClientToScreen	(	int *	x,
		int *	y
	)		const

Converts to screen coordinates from coordinates relative to this window.

Parameters:

x	A pointer to a integer value for the x coordinate. Pass the client coordinate in, and a screen coordinate will be passed out.
y	A pointer to a integer value for the y coordinate. Pass the client coordinate in, and a screen coordinate will be passed out.

wxPerl Note: In wxPerl this method returns a 2-element list instead of modifying its parameters.

wxPoint wxWindow::ClientToScreen ( const wxPoint & pt ) const

Converts to screen coordinates from coordinates relative to this window.

Parameters:

pt	The client position for the second form of the function.

virtual wxSize wxWindow::ClientToWindowSize ( const wxSize & size ) const [virtual]

Converts client area size size to corresponding window size.

In other words, the returned value is what would GetSize() return if this window had client area of given size. Components with wxDefaultCoord value are left unchanged. Note that the conversion is not always exact, it assumes that non-client area doesn't change and so doesn't take into account things like menu bar (un)wrapping or (dis)appearance of the scrollbars.

Since:: 2.8.8

参照:: WindowToClientSize()

bool wxWindow::Close ( bool force = false )

This function simply generates a wxCloseEvent whose handler usually tries to close the window.

It doesn't close the window itself, however.

Parameters:

force false if the window's close handler should be able to veto the destruction of this window, true if it cannot.

注意:: Close calls the close handler for the window, providing an opportunity for the window to choose whether to destroy the window. Usually it is only used with the top level windows (wxFrame and wxDialog classes) as the others are not supposed to have any special OnClose() logic. The close handler should check whether the window is being deleted forcibly, using wxCloseEvent::CanVeto, in which case it should destroy the window using wxWindow::Destroy. Note that calling Close does not guarantee that the window will be destroyed; but it provides a way to simulate a manual close of a window, which may or may not be implemented by destroying the window. The default implementation of wxDialog::OnCloseWindow does not necessarily delete the dialog, since it will simply simulate an wxID_CANCEL event which is handled by the appropriate button event handler and may do anything at all. To guarantee that the window will be destroyed, call wxWindow::Destroy instead

参照:: Window Deletion Overview, Destroy(), wxCloseEvent

wxPoint wxWindow::ConvertDialogToPixels ( const wxPoint & pt ) const

Converts a point or size from dialog units to pixels.

For the x dimension, the dialog units are multiplied by the average character width and then divided by 4. For the y dimension, the dialog units are multiplied by the average character height and then divided by 8.

注意:

Dialog units are used for maintaining a dialog's proportions even if the font changes. You can also use these functions programmatically. A convenience macro is defined:

                #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

参照:: ConvertPixelsToDialog()

wxSize wxWindow::ConvertDialogToPixels ( const wxSize & sz ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

wxPoint wxWindow::ConvertPixelsToDialog ( const wxPoint & pt ) const

Converts a point or size from pixels to dialog units.

For the x dimension, the pixels are multiplied by 4 and then divided by the average character width. For the y dimension, the pixels are multiplied by 8 and then divided by the average character height.

注意:: Dialog units are used for maintaining a dialog's proportions even if the font changes.

参照:: ConvertDialogToPixels()

wxSize wxWindow::ConvertPixelsToDialog ( const wxSize & sz ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

bool wxWindow::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `0`,
		const wxString &	name = `wxPanelNameStr`
	)

virtual bool wxWindow::Destroy ( ) [virtual]

安全にウィンドウを破棄します。

Use this function instead of the delete operator, since different window classes can be destroyed differently. Frames and dialogs are not destroyed immediately when this function is called -- they are added to a list of windows to be deleted on idle time, when all the window's events have been processed. This prevents problems with events being sent to non-existent windows.

Returns:: true if the window has either been successfully deleted, or it has been added to the list of windows pending real deletion.

bool wxWindow::DestroyChildren ( )

Destroys all children of a window.

Called automatically by the destructor.

bool wxWindow::Disable ( )

Disables the window.

Same as Enable() Enable(false).

Returns:: Returns true if the window has been disabled, false if it had been already disabled before the call to this function.

virtual void wxWindow::DoCentre ( int direction ) [protected, virtual]

Centres the window.

Parameters:

direction Specifies the direction for the centring. May be wxHORIZONTAL, wxVERTICAL or wxBOTH. It may also include the wxCENTRE_ON_SCREEN flag.

注意:: This function is not meant to be called directly by user code, but via Centre, Center, CentreOnParent, or CenterOnParent. This function can be overridden to fine-tune centring behaviour.

virtual int wxWindow::DoGetBestClientHeight ( int width ) const [protected, virtual]

Override this method to implement height-for-width best size calculation.

Return the height needed to fully display the control contents if its width is fixed to the given value. Custom classes implementing wrapping should override this method and return the height corresponding to the number of lines needed to lay out the control contents at this width.

Currently this method is not used by wxWidgets yet, however it is planned that it will be used by the new sizer classes implementing height-for-width layout strategy in the future.

Notice that implementing this method or even implementing both it and DoGetBestClientWidth() doesn't replace overriding DoGetBestClientSize(), i.e. you still need to implement the latter as well in order to provide the best size when neither width nor height are constrained.

By default returns wxDefaultCoord meaning that the vertical component of DoGetBestClientSize() return value should be used.

Since:: 2.9.4

virtual wxSize wxWindow::DoGetBestClientSize ( ) const [protected, virtual]

Override this method to return the best size for a custom control.

A typical implementation of this method should compute the minimal size needed to fully display the control contents taking into account the current font size.

The default implementation simply returns wxDefaultSize and GetBestSize() returns an arbitrary hardcoded size for the window, so you must override it when implementing a custom window class.

参照:: ウィンドウサイズの概要

Since:: 2.9.0

virtual int wxWindow::DoGetBestClientWidth ( int height ) const [protected, virtual]

Override this method to implement width-for-height best size calculation.

This method is exactly the same as DoGetBestClientHeight() except that it determines the width assuming the height is fixed instead of vice versa.

Since:: 2.9.4

virtual wxSize wxWindow::DoGetBestSize ( ) const [protected, virtual]

Implementation of GetBestSize() that can be overridden.

Notice that it is usually more convenient to override DoGetBestClientSize() rather than this method itself as you need to explicitly account for the window borders size if you do the latter.

The default implementation of this function is designed for use in container windows, such as wxPanel, and works something like this:

ウィンドウでサイザーが使用されていれば、それが最適サイズの計算に使用されます。
Otherwise if the window has layout constraints then those are used to calculate the best size.
そうでない場合、ウィンドウが子コントロールを持っていれば、すべての子コントロールを表示するのに充分な最適サイズが設定されます。
Otherwise if there are no children then the window's minimal size will be used as its best size.
Otherwise if there is no minimal size set, then the current size is used for the best size.

参照:: ウィンドウサイズの概要

Reimplemented in wxRichTextCtrl.

virtual void wxWindow::DoUpdateWindowUI ( wxUpdateUIEvent & event ) [virtual]

Does the window-specific updating after processing the update event.

This function is called by UpdateWindowUI() in order to check return values in the wxUpdateUIEvent and act appropriately. For example, to allow frame and dialog title updating, wxWidgets implements this function as follows:

        // do the window-specific processing after processing the update event
        void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
        {
            if ( event.GetSetEnabled() )
                Enable(event.GetEnabled());

            if ( event.GetSetText() )
            {
                if ( event.GetText() != GetTitle() )
                    SetTitle(event.GetText());
            }
        }

virtual void wxWindow::DragAcceptFiles ( bool accept ) [virtual]

Enables or disables eligibility for drop file events (OnDropFiles).

Parameters:

accept If true, the window is eligible for drop file events. If false, the window will not accept drop file events.

注意:: Windows only until version 2.8.9, available on all platforms since 2.8.10. Cannot be used together with SetDropTarget() on non-Windows platforms.

参照:: SetDropTarget()

virtual bool wxWindow::Enable ( bool enable = true ) [virtual]

Enable or disable the window for user input.

Note that when a parent window is disabled, all of its children are disabled as well and they are reenabled again when the parent is.

Parameters:

enable If true, enables the window for input. If false, disables the window.

Returns:: Returns true if the window has been enabled or disabled, false if nothing was done, i.e. if the window had already been in the specified state.

参照:: IsEnabled(), Disable(), wxRadioBox::Enable

Find a child of this window, by id.

May return this if it matches itself.

wxWindow* wxWindow::FindWindow ( const wxString & name ) const

static wxWindow* wxWindow::FindWindowById	(	long	id,
		const wxWindow *	parent = `0`
	)		`[static]`

Find the first window with the given id.

Returns:: Window with the given id or NULL if not found.

static wxWindow* wxWindow::FindWindowByLabel	(	const wxString &	label,
		const wxWindow *	parent = `0`
	)		`[static]`

Find a window by its label.

Depending on the type of window, the label may be a window title or panel item label. If parent is NULL, the search will start from all top-level frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy. The search is recursive in both cases.

参照:: FindWindow()

Returns:: Window with the given label or NULL if not found.

static wxWindow* wxWindow::FindWindowByName	(	const wxString &	name,
		const wxWindow *	parent = `0`
	)		`[static]`

Find a window by its name (as given in a window constructor or Create() function call).

If parent is NULL, the search will start from all top-level frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy.

The search is recursive in both cases. If no window with such name is found, FindWindowByLabel() is called.

参照:: FindWindow()

Returns:: Window with the given name or NULL if not found.

virtual void wxWindow::Fit ( ) [virtual]

サブウィンドウにフィットするようにウィンドウのサイズを設定します。

This function won't do anything if there are no subwindows and will only really work correctly if sizers are used for the subwindows layout.

Also, if the window has exactly one subwindow it is better (faster and the result is more precise as Fit() adds some margin to account for fuzziness of its calculations) to call:

        window->SetClientSize(child->GetSize());

instead of calling Fit().

参照:: ウィンドウサイズの概要

virtual void wxWindow::FitInside ( ) [virtual]

Similar to Fit(), but sizes the interior (virtual) size of a window.

Mainly useful with scrolled windows to reset scrollbars after sizing changes that do not trigger a size event, and/or scrolled windows without an interior sizer. This function similarly won't do anything if there are no subwindows.

void wxWindow::Freeze ( )

ウィンドウをフリーズ、つまり、画面上のいかなる更新も行われないようにします。これを行なうとウィンドウはまったく再描画されなくなります。

Thaw() must be called to reenable window redrawing. Calls to these two functions may be nested but to ensure that the window is properly repainted again, you must thaw it exactly as many times as you froze it.

If the window has any children, they are recursively frozen too.

This method is useful for visual appearance optimization (for example, it is a good idea to use it before doing many large text insertions in a row into a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all controls so it is mostly just a hint to wxWidgets and not a mandatory directive.

wxAcceleratorTable* wxWindow::GetAcceleratorTable ( )

Gets the accelerator table for this window.

See wxAcceleratorTable.

wxAccessible* wxWindow::GetAccessible ( )

Returns the accessible object for this window, if any.

See also wxAccessible.

bool wxWindow::GetAutoLayout ( ) const

Returns the sizer of which this window is a member, if any, otherwise NULL.

wxColour wxWindow::GetBackgroundColour ( ) const

Returns the background colour of the window.

int wxWindow::GetBestHeight ( int width ) const

Returns the best height needed by this window if it had the given width.

参照:: DoGetBestClientHeight()

Since:: 2.9.4

wxSize wxWindow::GetBestSize ( ) const

This functions returns the best acceptable minimal size for the window.

For example, for a static control, it will be the minimal size such that the control label is not truncated. For windows containing subwindows (typically wxPanel), the size returned by this function will be the same as the size the window would have had after calling Fit().

Override virtual DoGetBestSize() or, better, because it's usually more convenient, DoGetBestClientSize() when writing your own custom window class to change the value returned by this public non-virtual method.

参照:: CacheBestSize(), Window Sizing Overview

Reimplemented in wxMediaCtrl.

virtual wxSize wxWindow::GetBestVirtualSize ( ) const [virtual]

Return the largest of ClientSize and BestSize (as determined by a sizer, interior children, or other means)

int wxWindow::GetBestWidth ( int height ) const

Returns the best width needed by this window if it had the given height.

参照:: DoGetBestClientWidth()

Since:: 2.9.4

wxBorder wxWindow::GetBorder ( long flags ) const

Get the window border style from the given flags: this is different from simply doing flags & wxBORDER_MASK because it uses GetDefaultBorder() to translate wxBORDER_DEFAULT to something reasonable.

wxBorder wxWindow::GetBorder ( ) const

Get border for the flags of this window.

static wxWindow* wxWindow::GetCapture ( ) [static]

Returns the currently captured window.

参照:: HasCapture(), CaptureMouse(), ReleaseMouse(), wxMouseCaptureLostEvent, wxMouseCaptureChangedEvent

wxCaret* wxWindow::GetCaret ( ) const

Returns the caret() associated with the window.

virtual int wxWindow::GetCharHeight ( ) const [virtual]

Returns the character height for this window.

virtual int wxWindow::GetCharWidth ( ) const [virtual]

Returns the average character width for this window.

wxWindowList& wxWindow::GetChildren ( )

Returns a reference to the list of the window's children.

wxWindowList is a type-safe wxList-like class whose elements are of type wxWindow*.

const wxWindowList& wxWindow::GetChildren ( ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

static wxVisualAttributes wxWindow::GetClassDefaultAttributes ( wxWindowVariant variant = wxWINDOW_VARIANT_NORMAL ) [static]

Returns the default font and colours which are used by the control.

This is useful if you want to use the same font or colour in your own control as in a standard control -- which is a much better idea than hard coding specific colours or fonts which might look completely out of place on the users system, especially if it uses themes.

The variant parameter is only relevant under Mac currently and is ignore under other platforms. Under Mac, it will change the size of the returned font. See SetWindowVariant() for more about this.

This static method is "overridden" in many derived classes and so calling, for example, wxButton::GetClassDefaultAttributes() will typically return the values appropriate for a button which will be normally different from those returned by, say, wxListCtrl::GetClassDefaultAttributes().

The wxVisualAttributes structure has at least the fields font, colFg and colBg. All of them may be invalid if it was not possible to determine the default control appearance or, especially for the background colour, if the field doesn't make sense as is the case for colBg for the controls with themed background.

参照:: InheritAttributes()

virtual wxPoint wxWindow::GetClientAreaOrigin ( ) const [virtual]

Get the origin of the client area of the window relative to the window top left corner (the client area may be shifted because of the borders, scrollbars, other decorations...)

Reimplemented in wxFrame.

wxRect wxWindow::GetClientRect ( ) const

Get the client rectangle in window (i.e.

client) coordinates

void wxWindow::GetClientSize	(	int *	width,
		int *	height
	)		const

Returns the size of the window 'client area' in pixels.

The client area is the area which may be drawn on by the programmer, excluding title bar, border, scrollbars, etc. Note that if this window is a top-level one and it is currently minimized, the return size is empty (both width and height are 0).

wxPerl Note: In wxPerl this method takes no parameters and returns a 2-element list (width, height).

wxSize wxWindow::GetClientSize ( ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

wxLayoutConstraints* wxWindow::GetConstraints ( ) const

Returns a pointer to the window's layout constraints, or NULL if there are none.

wxSizer* wxWindow::GetContainingSizer ( ) const

Returns the sizer of which this window is a member, if any, otherwise NULL.

const wxCursor& wxWindow::GetCursor ( ) const

Return the cursor associated with this window.

参照:: SetCursor()

virtual wxVisualAttributes wxWindow::GetDefaultAttributes ( ) const [virtual]

Currently this is the same as calling wxWindow::GetClassDefaultAttributes(wxWindow::GetWindowVariant()).

One advantage of using this function compared to the static version is that the call is automatically dispatched to the correct class (as usual with virtual functions) and you don't have to specify the class name explicitly.

The other one is that in the future this function could return different results, for example it might return a different font for an "Ok" button than for a generic button if the users GUI is configured to show such buttons in bold font. Of course, the down side is that it is impossible to call this function without actually having an object to apply it to whereas the static version can be used without having to create an object first.

virtual wxDropTarget* wxWindow::GetDropTarget ( ) const [virtual]

Returns the associated drop target, which may be NULL.

参照:: SetDropTarget(), Drag and Drop Overview

virtual wxSize wxWindow::GetEffectiveMinSize ( ) const [virtual]

ウィンドウの最適サイズを最小サイズにマージし、その結果を返却します。

This is the value used by sizers to determine the appropriate amount of space to allocate for the widget.

This is the method called by a wxSizer when it queries the size of a window or control.

wxPerl Note: This method will return an integer in wxPerl.

wxString wxWindow::GetHelpText ( ) const

Gets the help text to be used as context-sensitive help for this window.

Note that the text is actually stored by the current wxHelpProvider implementation, and not in the window object itself.

参照:: SetHelpText(), GetHelpTextAtPoint(), wxHelpProvider

virtual wxString wxWindow::GetHelpTextAtPoint	(	const wxPoint &	point,
		wxHelpEvent::Origin	origin
	)		const `[virtual]`

Gets the help text to be used as context-sensitive help for this window.

This method should be overridden if the help message depends on the position inside the window, otherwise GetHelpText() can be used.

Parameters:

point	Coordinates of the mouse at the moment of help event emission.
origin	Help event origin, see also wxHelpEvent::GetOrigin.

wxWindowID wxWindow::GetId ( ) const

Returns the identifier of the window.

注意:: Each window has an integer identifier. If the application has not provided one (or the default wxID_ANY) a unique identifier with a negative value will be generated.

参照:: SetId(), Window IDs

virtual wxString wxWindow::GetLabel ( ) const [virtual]

Generic way of getting a label from any window, for identification purposes.

注意:: The interpretation of this function differs from class to class. For frames and dialogs, the value returned is the title. For buttons or static text controls, it is the button text. This function can be useful for meta-programs (such as testing tools or special-needs access programs) which need to identify windows by name.

Reimplemented in wxButton, wxCommandLinkButton, and wxControl.

virtual wxLayoutDirection wxWindow::GetLayoutDirection ( ) const [virtual]

Returns the layout direction for this window, Note that wxLayout_Default is returned if layout direction is not supported.

virtual wxSize wxWindow::GetMaxClientSize ( ) const [virtual]

int wxWindow::GetPopupMenuSelectionFromUser	(	wxMenu &	menu,
		const wxPoint &	pos = `wxDefaultPosition`
	)

This function shows a popup menu at the given position in this window and returns the selected id.

It can be more convenient than the general purpose PopupMenu() function for simple menus proposing a choice in a list of strings to the user.

Notice that to avoid unexpected conflicts between the (usually consecutive range of) ids used by the menu passed to this function and the existing EVT_UPDATE_UI() handlers, this function temporarily disables UI updates for the window, so you need to manually disable (or toggle or ...) any items which should be disabled in the menu before showing it.

The parameter menu is the menu to show. The parameter pos (or the parameters x and y) is the position at which to show the menu in client coordinates. It is recommended to not explicitly specify coordinates when calling this method in response to mouse click, because some of the ports (namely, wxGTK) can do a better job of positioning the menu in that case.

Returns:: The selected menu item id or wxID_NONE if none selected or an error occurred.

Since:: 2.9.0

int wxWindow::GetPopupMenuSelectionFromUser	(	wxMenu &	menu,

Parameters:

x	Receives the x position of the window if non-NULL.
y	Receives the y position of the window if non-NULL.

wxPerl Note: In wxPerl this method is implemented as GetPositionXY() returning a 2-element list (x, y).

Note that if this window is a top-level one and it is currently minimized, the returned size is the restored window size, not the size of the window icon.

Parameters:

width	Receives the window width.
height	Receives the window height.

wxPerl Note: In wxPerl this method is implemented as GetSizeWH() returning a 2-element list (width, height).

The text extent is returned in the w and h pointers.

Parameters:

string	String whose extent is to be measured.
w	Return value for width.
h	Return value for height.
descent	Return value for descent (optional).
externalLeading	Return value for external leading (optional).
font	Font to use instead of the current window font (optional).

wxPerl Note: In wxPerl this method takes only the string and optionally font parameters, and returns a 4-element list (x, y, descent, externalLeading).

wxSize wxWindow::GetTextExtent ( const wxString & string ) const

Gets the dimensions of the string as it would be drawn on the window with the currently selected font.

virtual bool wxWindow::GetThemeEnabled ( ) const [virtual]

Clears the window by filling it with the current background colour.

Does not cause an erase background event to be generated.

Notice that this uses wxClientDC to draw on the window and the results of doing it while also drawing on wxPaintDC for this window are undefined. Hence this method shouldn't be used from EVT_PAINT handlers, just use wxDC::Clear() on the wxPaintDC you already use there instead.

wxToolTip* wxWindow::GetToolTip ( ) const

Get the associated tooltip or NULL if none.

wxString wxWindow::GetToolTipText ( ) const

Get the text of the associated tooltip or empty string if none.

wxRect wxWindow::GetUpdateClientRect ( ) const

Returns a pointer to the current validator for the window, or NULL if there is none.

wxSize wxWindow::GetVirtualSize ( ) const

wxWindowVariant wxWindow::GetWindowVariant ( ) const

Returns the value previously passed to SetWindowVariant().

bool wxWindow::HandleAsNavigationKey ( const wxKeyEvent & event )

参照:: FindFocus()

virtual bool wxWindow::HasMultiplePages ( ) const [virtual]

This method should be overridden to return true if this window has multiple pages.

All standard class with multiple pages such as wxNotebook, wxListbook and wxTreebook already override it to return true and user-defined classes with similar behaviour should also do so, to allow the library to handle such windows appropriately.

bool wxWindow::HasScrollbar ( int orient ) const

Returns true if this window currently has a scroll bar for this orientation.

This method may return false even when CanScroll() for the same orientation returns true, but if CanScroll() returns false, i.e. scrolling in this direction is not enabled at all, HasScrollbar() always returns false as well.

Parameters:

orient Orientation to check, either wxHORIZONTAL or wxVERTICAL.

virtual bool wxWindow::HasTransparentBackground ( ) [virtual]

Returns true if this window background is transparent (as, for example, for wxStaticText) and should show the parent window background.

This method is mostly used internally by the library itself and you normally shouldn't have to call it. You may, however, have to override it in your wxWindow-derived class to ensure that background is painted correctly.

bool wxWindow::Hide ( )

Equivalent to calling wxWindow::Show(false).

virtual bool wxWindow::HideWithEffect	(	wxShowEffect	effect,
		unsigned int	timeout = `0`
	)		`[virtual]`

This function hides a window, like Hide(), but using a special visual effect if possible.

Since:: 2.9.0

wxHitTest wxWindow::HitTest	(	wxCoord	x,
		wxCoord	y
	)		const

Get the window border style from the given flags: this is different from simply doing flags & wxBORDER_MASK because it uses GetDefaultBorder() to translate wxBORDER_DEFAULT to something reasonable.

Reimplemented in wxListBox.

wxHitTest wxWindow::HitTest ( const wxPoint & pt ) const

Get the window border style from the given flags: this is different from simply doing flags & wxBORDER_MASK because it uses GetDefaultBorder() to translate wxBORDER_DEFAULT to something reasonable.

Reimplemented in wxListBox, and wxPropertyGrid.

virtual bool wxWindow::InformFirstDirection	(	int	direction,
		int	size,
		int	availableOtherDir
	)		`[virtual]`

wxSizer and friends use this to give a chance to a component to recalc its min size once one of the final size components is known.

Override this function when that is useful (such as for wxStaticText which can stretch over several lines). Parameter availableOtherDir tells the item how much more space there is available in the opposite direction (-1 if unknown).

virtual void wxWindow::InheritAttributes ( ) [virtual]

This function is (or should be, in case of custom controls) called during window creation to intelligently set up the window visual attributes, that is the font and the foreground and background colours.

By "intelligently" the following is meant: by default, all windows use their own GetClassDefaultAttributes() default attributes. However if some of the parents attributes are explicitly (that is, using SetFont() and not wxWindow::SetOwnFont) changed and if the corresponding attribute hadn't been explicitly set for this window itself, then this window takes the same value as used by the parent. In addition, if the window overrides ShouldInheritColours() to return false, the colours will not be changed no matter what and only the font might.

This rather complicated logic is necessary in order to accommodate the different usage scenarios. The most common one is when all default attributes are used and in this case, nothing should be inherited as in modern GUIs different controls use different fonts (and colours) than their siblings so they can't inherit the same value from the parent. However it was also deemed desirable to allow to simply change the attributes of all children at once by just changing the font or colour of their common parent, hence in this case we do inherit the parents attributes.

virtual void wxWindow::InitDialog ( ) [virtual]

Sends an wxEVT_INIT_DIALOG event, whose handler usually transfers data to the dialog via validators.

Reimplemented in wxPanel.

void wxWindow::InvalidateBestSize ( )

Resets the cached best size value so it will be recalculated the next time it is needed.

参照:: CacheBestSize()

bool wxWindow::IsBeingDeleted ( ) const

Returns true if this window is in process of being destroyed.

Top level windows are not deleted immediately but are rather scheduled for later destruction to give them time to process any pending messages; see Destroy() description.

This function returns true if this window, or one of its parent windows, is scheduled for destruction and can be useful to avoid manipulating it as it's usually useless to do something with a window which is on the point of disappearing anyhow.

bool wxWindow::IsDescendant ( wxWindowBase * win ) const

Check if the specified window is a descendant of this one.

Returns true if the window is a descendant (i.e. a child or grand-child or grand-grand-child or ...) of this one.

Notice that a window can never be a descendant of another one if they are in different top level windows, i.e. a child of a wxDialog is not considered to be a descendant of dialogs parent wxFrame.

Parameters:

win	Any window, possible NULL (false is always returned then).

Since:: 2.9.4

virtual bool wxWindow::IsDoubleBuffered ( ) const [virtual]

bool wxWindow::IsEnabled ( ) const

Returns true if the window is enabled, i.e.

bool wxWindow::IsThisEnabled ( ) const

Returns true if this window is intrinsically enabled, false otherwise, i.e.

if Enable() Enable(false) had been called. This method is mostly used for wxWidgets itself, user code should normally use IsEnabled() instead.

virtual bool wxWindow::IsTopLevel ( ) const [virtual]

Returns true if the given window is a top-level one.

Currently all frames and dialogs are considered to be top-level windows (even if they have a parent window).

virtual bool wxWindow::IsTransparentBackgroundSupported ( wxString * reason = NULL ) const [virtual]

Checks whether using transparent background might work.

If this function returns false, calling SetBackgroundStyle() with wxBG_STYLE_TRANSPARENT is not going to work. If it returns true, setting transparent style should normally succeed.

Notice that this function would typically be called on the parent of a window you want to set transparent background style for as the window for which this method is called must be fully created.

Parameters:

reason If not NULL, a reason message is provided if transparency is not supported.

Returns:: true if background transparency is supported.

Since:: 2.9.4

virtual bool wxWindow::Layout ( ) [virtual]

Invokes the constraint-based layout algorithm or the sizer-based algorithm for this window.

		int	flags = `wxSIZE_USE_EXISTING`
	)

Moves the window to the given position.

Parameters:

x	Required x position.
y	Required y position.
flags	See SetSize() for more info about this parameter.

注意:

Implementations of SetSize can also implicitly implement the Move() function, which is defined in the base wxWindow class as the call:

                 SetSize(x, y, wxDefaultCoord, wxDefaultCoord, wxSIZE_USE_EXISTING);

参照:: SetSize()

void wxWindow::Move	(	const wxPoint &	pt,
		int	flags = `wxSIZE_USE_EXISTING`
	)

Moves the window to the given position.

Parameters:

pt	wxPoint object representing the position.
flags	See SetSize() for more info about this parameter.

注意:

Implementations of SetSize() can also implicitly implement the Move() function, which is defined in the base wxWindow class as the call:

                 SetSize(x, y, wxDefaultCoord, wxDefaultCoord, wxSIZE_USE_EXISTING);

void wxWindow::MoveAfterInTabOrder ( wxWindow * win )

Moves this window in the tab navigation order after the specified win.

This means that when the user presses TAB key on that other window, the focus switches to this window.

Default tab order is the same as creation order, this function and MoveBeforeInTabOrder() allow to change it after creating all the windows.

Parameters:

win	A sibling of this window which should precede it in tab order, must not be NULL

void wxWindow::MoveBeforeInTabOrder ( wxWindow * win )

Same as MoveAfterInTabOrder() except that it inserts this window just before win instead of putting it right after it.

bool wxWindow::Navigate ( int flags = wxNavigationKeyEvent::IsForward )

このウィンドウから始まるキーボードナビゲーション処理を実行します。

This method is equivalent to calling NavigateIn() method on the parent window.

Parameters:

flags A combination of wxNavigationKeyEvent::IsForward and wxNavigationKeyEvent::WinChange.

Returns:: Returns true if the focus was moved to another window or false if nothing changed.

注意:: You may wish to call this from a text control custom keypress handler to do the default navigation behaviour for the tab key, since the standard default behaviour for a multiline text control with the wxTE_PROCESS_TAB style is to insert a tab and not navigate to the next control. See also wxNavigationKeyEvent and HandleAsNavigationKey.

bool wxWindow::NavigateIn ( int flags = wxNavigationKeyEvent::IsForward )

Performs a keyboard navigation action inside this window.

See Navigate() for more information.

static wxWindowID wxWindow::NewControlId ( int count = 1 ) [static]

Create a new ID or range of IDs that are not currently in use.

The IDs will be reserved until assigned to a wxWindow ID or unreserved with UnreserveControlId().

See Window IDs for more information.

Parameters:

count The number of sequential IDs to reserve.

Returns:: Returns the ID or the first ID of the range (i.e. the most negative), or wxID_NONE if the specified number of identifiers couldn't be allocated.

参照:: UnreserveControlId(), wxIdManager, Window IDs

virtual void wxWindow::OnInternalIdle ( ) [virtual]

This virtual function is normally only used internally, but sometimes an application may need it to implement functionality that should not be disabled by an application defining an OnIdle handler in a derived class.

This function may be used to do delayed painting, for example, and most implementations call UpdateWindowUI() in order to send update events to the window in idle time.

bool wxWindow::PageDown ( )

Same as ScrollPages (1).

Reimplemented in wxStyledTextCtrl.

bool wxWindow::PageUp ( )

Same as ScrollPages (-1).

Reimplemented in wxStyledTextCtrl.

wxEvtHandler* wxWindow::PopEventHandler ( bool deleteHandler = false )

Removes and returns the top-most event handler on the event handler stack.

E.g. in the case of:

when calling W->PopEventHandler(), the event handler A will be removed and B will be the first handler of the stack.

Note that it's an error to call this function when no event handlers were pushed on this window (i.e. when the window itself is its only event handler).

Parameters:

deleteHandler If this is true, the handler will be deleted after it is removed (and the returned value will be NULL).

参照:: イベント処理の仕組み

bool wxWindow::PopupMenu	(	wxMenu *	menu,
		int	x,
		int	y
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

bool wxWindow::PopupMenu	(	wxMenu *	menu,
		const wxPoint &	pos = `wxDefaultPosition`
	)

Pops up the given menu at the specified coordinates, relative to this window, and returns control when the user has dismissed the menu.

If a menu item is selected, the corresponding menu event is generated and will be processed as usual. If coordinates are not specified, the current mouse cursor position is used.

menu is the menu to pop up.

The position where the menu will appear can be specified either as a wxPoint pos or by two integers (x and y).

注意:: Just before the menu is popped up, wxMenu::UpdateUI is called to ensure that the menu items are in the correct state. The menu does not get deleted by the window. It is recommended to not explicitly specify coordinates when calling PopupMenu in response to mouse click, because some of the ports (namely, wxGTK) can do a better job of positioning the menu in that case.

参照:: wxMenu

void wxWindow::PostSizeEvent ( )

Posts a size event to the window.

This is the same as SendSizeEvent() with wxSEND_EVENT_POST argument.

void wxWindow::PostSizeEventToParent ( )

Posts a size event to the parent of this window.

This is the same as SendSizeEventToParent() with wxSEND_EVENT_POST argument.

virtual bool wxWindow::ProcessEvent ( wxEvent & event ) [protected, virtual]

This function is public in wxEvtHandler but protected in wxWindow because for wxWindows you should always call ProcessEvent() on the pointer returned by GetEventHandler() and not on the wxWindow object itself.

For convenience, a ProcessWindowEvent() method is provided as a synonym for

 GetEventHandler()->ProcessEvent()

Note that it's still possible to call these functions directly on the wxWindow object (e.g. casting it to wxEvtHandler) but doing that will create subtle bugs when windows with event handlers pushed on them are involved.

This holds also for all other wxEvtHandler functions.

Reimplemented from wxEvtHandler.

void wxWindow::ProcessPendingEvents ( ) [protected]

See ProcessEvent() for more info about why you shouldn't use this function and the reason for making this function protected in wxWindow.

Reimplemented from wxEvtHandler.

bool wxWindow::ProcessThreadEvent ( const wxEvent & event ) [protected]

See ProcessEvent() for more info about why you shouldn't use this function and the reason for making this function protected in wxWindow.

bool wxWindow::ProcessWindowEvent ( wxEvent & event )

Convenient wrapper for ProcessEvent().

This is the same as writing

 GetEventHandler()->ProcessEvent(event);

but more convenient. Notice that ProcessEvent() itself can't be called for wxWindow objects as it ignores the event handlers associated with the window; use this function instead.

bool wxWindow::ProcessWindowEventLocally ( wxEvent & event )

Wrapper for wxEvtHandler::ProcessEventLocally().

This method is similar to ProcessWindowEvent() but can be used to search for the event handler only in this window and any event handlers pushed on top of it. Unlike ProcessWindowEvent() it won't propagate the event upwards. But it will use the validator and event handlers associated with this window, if any.

Since:: 2.9.1

void wxWindow::PushEventHandler ( wxEvtHandler * handler )

このイベントハンドラをウィンドウのイベントスタック上に追加します。

An event handler is an object that is capable of processing the events sent to a window. By default, the window is its own event handler, but an application may wish to substitute another, for example to allow central implementation of event-handling for a variety of different window classes.

wxWindow::PushEventHandler allows an application to set up a stack of event handlers, where an event not handled by one event handler is handed to the next one in the chain.

E.g. if you have two event handlers A and B and a wxWindow instance W and you call:

            W->PushEventHandler(A);
            W->PushEventHandler(B);

you will end up with the following situation:

Note that you can use wxWindow::PopEventHandler to remove the event handler.

Parameters:

handler Specifies the handler to be pushed. It must not be part of a wxEvtHandler chain; an assert will fail if it's not unlinked (see wxEvtHandler::IsUnlinked).

virtual void wxWindow::QueueEvent ( wxEvent * event ) [protected, virtual]

See ProcessEvent() for more info about why you shouldn't use this function and the reason for making this function protected in wxWindow.

Reimplemented from wxEvtHandler.

virtual void wxWindow::Raise ( ) [virtual]

Raises the window to the top of the window hierarchy (Z-order).

Notice that this function only requests the window manager to raise this window to the top of Z-order. Depending on its configuration, the window manager may raise the window, not do it at all or indicate that a window requested to be raised in some other way, e.g. by flashing its icon if it is minimized.

注意:: This function only works for wxTopLevelWindow-derived classes.

参照:: Lower()

virtual void wxWindow::Refresh	(	bool	eraseBackground = `true`,
		const wxRect *	rect = `NULL`
	)		`[virtual]`

Causes this window, and all of its children recursively (except under wxGTK1 where this is not implemented), to be repainted.

Note that repainting doesn't happen immediately but only during the next event loop iteration, if you need to update the window immediately you should use Update() instead.

Parameters:

eraseBackground	If true, the background will be erased.
rect	If non-NULL, only the given rectangle will be treated as damaged.

参照:: RefreshRect()

Reimplemented in wxMenuBar.

void wxWindow::RefreshRect	(	const wxRect &	rect,
		bool	eraseBackground = `true`
	)

Redraws the contents of the given rectangle: only the area inside it will be repainted.

This is the same as Refresh() but has a nicer syntax as it can be called with a temporary wxRect object as argument like this RefreshRect(wxRect(x, y, w, h)).

virtual bool wxWindow::RegisterHotKey	(	int	hotkeyId,
		int	modifiers,
		int	virtualKeyCode
	)		`[virtual]`

Registers a system wide hotkey.

Every time the user presses the hotkey registered here, this window will receive a hotkey event.

It will receive the event even if the application is in the background and does not have the input focus because the user is working with some other application.

Parameters:

hotkeyId	Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If this function is called from a shared DLL, it must be a system wide unique identifier between 0xC000 and 0xFFFF. This is a MSW specific detail.
modifiers	A bitwise combination of wxMOD_SHIFT, wxMOD_CONTROL, wxMOD_ALT or wxMOD_WIN specifying the modifier keys that have to be pressed along with the key.
virtualKeyCode	The virtual key code of the hotkey.

Returns:: true if the hotkey was registered successfully. false if some other application already registered a hotkey with this modifier/virtualKeyCode combination.

注意:: Use EVT_HOTKEY(hotkeyId, fnc) in the event table to capture the event. This function is currently only implemented under Windows. It is used in the Windows CE port for detecting hardware button presses.

参照:: UnregisterHotKey()

void wxWindow::ReleaseMouse ( )

Releases mouse input captured with CaptureMouse().

参照:: CaptureMouse(), HasCapture(), ReleaseMouse(), wxMouseCaptureLostEvent, wxMouseCaptureChangedEvent

virtual void wxWindow::RemoveChild ( wxWindow * child ) [virtual]

Removes a child window.

This is called automatically by window deletion functions so should not be required by the application programmer. Notice that this function is mostly internal to wxWidgets and shouldn't be called by the user code.

Parameters:

child Child window to remove.

bool wxWindow::RemoveEventHandler ( wxEvtHandler * handler )

Find the given handler in the windows event handler stack and removes (but does not delete) it from the stack.

See wxEvtHandler::Unlink() for more info.

Parameters:

handler The event handler to remove, must be non-NULL and must be present in this windows event handlers stack.

Returns:: Returns true if it was found and false otherwise (this also results in an assert failure so this function should only be called when the handler is supposed to be there).

参照:: PushEventHandler(), PopEventHandler()

virtual bool wxWindow::Reparent ( wxWindow * newParent ) [virtual]

Reparents the window, i.e.

the window will be removed from its current parent window (e.g. a non-standard toolbar in a wxFrame) and then re-inserted into another.

Notice that currently you need to explicitly call wxNotebook::RemovePage() before reparenting a notebook page.

Parameters:

newParent New parent.

bool wxWindow::SafelyProcessEvent ( wxEvent & event ) [protected]

See ProcessEvent() for more info about why you shouldn't use this function and the reason for making this function protected in wxWindow.

Reimplemented from wxEvtHandler.

void wxWindow::ScreenToClient	(	int *	x,
		int *	y
	)		const

Converts from screen to client window coordinates.

Parameters:

x	Stores the screen x coordinate and receives the client x coordinate.
y	Stores the screen x coordinate and receives the client x coordinate.

wxPoint wxWindow::ScreenToClient ( const wxPoint & pt ) const

Converts from screen to client window coordinates.

Parameters:

pt	The screen position.

virtual bool wxWindow::ScrollLines ( int lines ) [virtual]

Scrolls the window by the given number of lines down (if lines is positive) or up.

Returns:: Returns true if the window was scrolled, false if it was already on top/bottom and nothing was done.

注意:: This function is currently only implemented under MSW and wxTextCtrl under wxGTK (it also works for wxScrolled classes under all platforms).

参照:: ScrollPages()

Reimplemented in wxRibbonGallery, and wxRibbonPage.

virtual bool wxWindow::ScrollPages ( int pages ) [virtual]

Scrolls the window by the given number of pages down (if pages is positive) or up.

Returns:: Returns true if the window was scrolled, false if it was already on top/bottom and nothing was done.

注意:: This function is currently only implemented under MSW and wxGTK.

参照:: ScrollLines()

virtual void wxWindow::ScrollWindow	(	int	dx,
		int	dy,
		const wxRect *	rect = `NULL`
	)		`[virtual]`

Physically scrolls the pixels in the window and move child windows accordingly.

Parameters:

dx	Amount to scroll horizontally.
dy	Amount to scroll vertically.
rect	Rectangle to scroll, if it is NULL, the whole window is scrolled (this is always the case under wxGTK which doesn't support this parameter)

注意:: Note that you can often use wxScrolled instead of using this function directly.

void wxWindow::SendDestroyEvent ( ) [protected]

Generate wxWindowDestroyEvent for this window.

This is called by the window itself when it is being destroyed and usually there is no need to call it but see wxWindowDestroyEvent for explanations of when you might want to do it.

virtual void wxWindow::SendSizeEvent ( int flags = 0 ) [virtual]

This function sends a dummy size event to the window allowing it to re-layout its children positions.

It is sometimes useful to call this function after adding or deleting a children after the frame creation or if a child size changes. Note that if the frame is using either sizers or constraints for the children layout, it is enough to call wxWindow::Layout() directly and this function should not be used in this case.

If flags includes wxSEND_EVENT_POST value, this function posts the event, i.e. schedules it for later processing, instead of dispatching it directly. You can also use PostSizeEvent() as a more readable equivalent of calling this function with this flag.

Parameters:

flags May include wxSEND_EVENT_POST. Default value is 0.

void wxWindow::SendSizeEventToParent ( int flags = 0 )

Safe wrapper for GetParent()->SendSizeEvent().

This function simply checks that the window has a valid parent which is not in process of being deleted and calls SendSizeEvent() on it. It is used internally by windows such as toolbars changes to whose state should result in parent re-layout (e.g. when a toolbar is added to the top of the window, all the other windows must be shifted down).

参照:: PostSizeEventToParent()

Parameters:

flags See description of this parameter in SendSizeEvent() documentation.

virtual void wxWindow::SetAcceleratorTable ( const wxAcceleratorTable & accel ) [virtual]

Sets the accelerator table for this window.

See wxAcceleratorTable.

void wxWindow::SetAccessible ( wxAccessible * accessible )

Sets the accessible for this window.

Any existing accessible for this window will be deleted first, if not identical to accessible. See also wxAccessible.

void wxWindow::SetAutoLayout ( bool autoLayout )

Determines whether the Layout() function will be called automatically when the window is resized.

This method is called implicitly by SetSizer() but if you use SetConstraints() you should call it manually or otherwise the window layout won't be correctly updated when its size changes.

Parameters:

autoLayout Set this to true if you wish the Layout() function to be called automatically when the window is resized.

参照:: SetSizer(), SetConstraints()

virtual bool wxWindow::SetBackgroundColour ( const wxColour & colour ) [virtual]

Sets the background colour of the window.

Notice that as with SetForegroundColour(), setting the background colour of a native control may not affect the entire control and could be not supported at all depending on the control and platform.

Please see InheritAttributes() for explanation of the difference between this method and SetOwnBackgroundColour().

Parameters:

colour The colour to be used as the background colour; pass wxNullColour to reset to the default colour. Note that you may want to use wxSystemSettings::GetColour() to retrieve a suitable colour to use rather than setting an hard-coded one.

注意:: The background colour is usually painted by the default wxEraseEvent event handler function under Windows and automatically under GTK. Note that setting the background colour does not cause an immediate refresh, so you may wish to call wxWindow::ClearBackground or wxWindow::Refresh after calling this function. Using this function will disable attempts to use themes for this window, if the system supports them. Use with care since usually the themes represent the appearance chosen by the user to be used for all applications on the system.

Returns:: true if the colour was really changed, false if it was already set to this colour and nothing was done.

参照:: GetBackgroundColour(), SetForegroundColour(), GetForegroundColour(), ClearBackground(), Refresh(), wxEraseEvent, wxSystemSettings

Reimplemented in wxListCtrl.

virtual bool wxWindow::SetBackgroundStyle ( wxBackgroundStyle style ) [virtual]

Sets the background style of the window.

The default background style is wxBG_STYLE_ERASE which indicates that the window background may be erased in EVT_ERASE_BACKGROUND handler. This is a safe, compatibility default; however you may want to change it to wxBG_STYLE_SYSTEM if you don't define any erase background event handlers at all, to avoid unnecessary generation of erase background events and always let system erase the background. And you should change the background style to wxBG_STYLE_PAINT if you define an EVT_PAINT handler which completely overwrites the window background as in this case erasing it previously, either in EVT_ERASE_BACKGROUND handler or in the system default handler, would result in flicker as the background pixels will be repainted twice every time the window is redrawn. Do ensure that the background is entirely erased by your EVT_PAINT handler in this case however as otherwise garbage may be left on screen.

Notice that in previous versions of wxWidgets a common way to work around the above mentioned flickering problem was to define an empty EVT_ERASE_BACKGROUND handler. Setting background style to wxBG_STYLE_PAINT is a simpler and more efficient solution to the same problem.

Under wxGTK and wxOSX, you can use wxBG_STYLE_TRANSPARENT to obtain full transparency of the window background. Note that wxGTK supports this only since GTK 2.12 with a compositing manager enabled, call IsTransparentBackgroundSupported() to check whether this is the case.

Also, on order for SetBackgroundStyle(wxBG_STYLE_TRANSPARENT) to work, it must be called before Create(). If you're using your own wxWindow-derived class you should write your code in the following way:

            class MyWidget : public wxWindow
            {
            public:
                MyWidget(wxWindow* parent, ...)
                    : wxWindow() // Use default ctor here!
                {
                    // Do this first:
                    SetBackgroundStyle(wxBG_STYLE_TRANSPARENT);

                    // And really create the window afterwards:
                    Create(parent, ...);
                }
            };

参照:: SetBackgroundColour(), GetForegroundColour(), SetTransparent(), IsTransparentBackgroundSupported()

virtual void wxWindow::SetCanFocus ( bool canFocus ) [virtual]

This method is only implemented by ports which have support for native TAB traversal (such as GTK+ 2.0).

It is called by wxWidgets' container control code to give the native system a hint when doing TAB traversal. A call to this does not disable or change the effect of programmatically calling SetFocus().

参照:: wxFocusEvent, wxPanel::SetFocus, wxPanel::SetFocusIgnoringChildren

void wxWindow::SetCaret ( wxCaret * caret )

Sets the caret() associated with the window.

void wxWindow::SetClientSize ( const wxSize & size )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void wxWindow::SetClientSize ( const wxRect & rect )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void wxWindow::SetClientSize	(	int	width,
		int	height
	)

This sets the size of the window client area in pixels.

Using this function to size a window tends to be more device-independent than SetSize(), since the application need not worry about what dimensions the border or title bar have when trying to fit the window around panel items, for example.

参照:: ウィンドウサイズの概要

void wxWindow::SetConstraints ( wxLayoutConstraints * constraints )

Sets the window to have the given layout constraints.

The window will then own the object, and will take care of its deletion. If an existing layout constraints object is already owned by the window, it will be deleted.

Parameters:

constraints The constraints to set. Pass NULL to disassociate and delete the window's constraints.

注意:: You must call SetAutoLayout() to tell a window to use the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout() explicitly. When setting both a wxLayoutConstraints and a wxSizer, only the sizer will have effect.

void wxWindow::SetContainingSizer ( wxSizer * sizer )

This normally does not need to be called by user code.

It is called when a window is added to a sizer, and is used so the window can remove itself from the sizer when it is destroyed.

virtual bool wxWindow::SetCursor ( const wxCursor & cursor ) [virtual]

Sets the window's cursor.

Notice that the window cursor also sets it for the children of the window implicitly.

The cursor may be wxNullCursor in which case the window cursor will be reset back to default.

Parameters:

cursor Specifies the cursor that the window should normally display.

参照:: wxSetCursor, wxCursor

void wxWindow::SetDoubleBuffered ( bool on )

Turn on or off double buffering of the window if the system supports it.

virtual void wxWindow::SetDropTarget ( wxDropTarget * target ) [virtual]

void wxWindow::SetEventHandler ( wxEvtHandler * handler )

このウィンドウのイベントハンドラを設定します。

Note that if you use this function you may want to use as the "next" handler of handler the window itself; in this way when handler doesn't process an event, the window itself will have a chance to do it.

Parameters:

handler Specifies the handler to be set. Cannot be NULL.

virtual void wxWindow::SetFocusFromKbd ( ) [virtual]

This function is called by wxWidgets keyboard navigation code when the user gives the focus to this window from keyboard (e.g.

using TAB key).

By default this method simply calls SetFocus() but can be overridden to do something in addition to this in the derived classes.

virtual bool wxWindow::SetFont ( const wxFont & font ) [virtual]

Sets the font for this window.

This function should not be called for the parent window if you don't want its font to be inherited by its children, use SetOwnFont() instead in this case and see InheritAttributes() for more explanations.

Please notice that the given font is not automatically used for wxPaintDC objects associated with this window, you need to call wxDC::SetFont too. However this font is used by any standard controls for drawing their text as well as by GetTextExtent().

Parameters:

font	Font to associate with this window, pass wxNullFont to reset to the default font.

Returns:: true if the font was really changed, false if it was already set to this font and nothing was done.

参照:: GetFont(), InheritAttributes()

Reimplemented in wxAuiNotebook, wxAuiToolBar, wxInfoBar, and wxRichTextCtrl.

virtual bool wxWindow::SetForegroundColour ( const wxColour & colour ) [virtual]

Sets the foreground colour of the window.

The meaning of foreground colour varies according to the window class; it may be the text colour or other colour, or it may not be used at all. Additionally, not all native controls support changing their foreground colour so this method may change their colour only partially or even not at all.

Please see InheritAttributes() for explanation of the difference between this method and SetOwnForegroundColour().

Parameters:

colour The colour to be used as the foreground colour; pass wxNullColour to reset to the default colour.

Returns:: true if the colour was really changed, false if it was already set to this colour and nothing was done.

void wxWindow::SetId ( wxWindowID winid )

Sets the identifier of the window.

注意:: Each window has an integer identifier. If the application has not provided one, an identifier will be generated. Normally, the identifier should be provided on creation and should not be modified subsequently.

virtual void wxWindow::SetInitialBestSize ( const wxSize & size ) [protected, virtual]

Sets the initial window size if none is given (i.e.

at least one of the components of the size passed to ctor/Create() is wxDefaultCoord).

Deprecated:: Use SetInitialSize() instead.

void wxWindow::SetInitialSize ( const wxSize & size = wxDefaultSize )

A smart SetSize that will fill in default size components with the window's best size values.

Also sets the window's minsize to the value passed in for use with sizers. This means that if a full or partial size is passed to this function then the sizers will use that size instead of the results of GetBestSize() to determine the minimum needs of the window for layout.

Most controls will use this to set their initial size, and their min size to the passed in value (if any.)

virtual void wxWindow::SetMinClientSize ( const wxSize & size ) [virtual]

Sets the minimum client size of the window, to indicate to the sizer layout mechanism that this is the minimum required size of window's client area.

You may need to call this if you change the window size after construction and before adding to its parent sizer.

Note, that just as with SetMinSize(), calling this method doesn't prevent the program from explicitly making the window smaller than the specified size.

Note that this method is just a shortcut for:

Sets the minimum size of the window, to indicate to the sizer layout mechanism that this is the minimum required size.

You may need to call this if you change the window size after construction and before adding to its parent sizer.

Notice that calling this method doesn't prevent the program from making the window explicitly smaller than the specified size by calling SetSize(), it just ensures that it won't become smaller than this size during the automatic layout.

virtual void wxWindow::SetScrollbar	(	int	orientation,
		int	position,
		int	thumbSize,
		int	range,
		bool	refresh = `true`
	)		`[virtual]`

Sets the scrollbar properties of a built-in scrollbar.

Parameters:

orientation	Determines the scrollbar whose page size is to be set. May be wxHORIZONTAL or wxVERTICAL.
position	The position of the scrollbar in scroll units.
thumbSize	The size of the thumb, or visible portion of the scrollbar, in scroll units.
range	The maximum position of the scrollbar. Value of -1 can be used to ask for the scrollbar to be shown but in the disabled state: this can be used to avoid removing the scrollbar even when it is not needed (currently this is only implemented in wxMSW port).
refresh	true to redraw the scrollbar, false otherwise.

注意:

Let's say you wish to display 50 lines of text, using the same font. The window is sized so that you can only see 16 lines at a time. You would use:

            SetScrollbar(wxVERTICAL, 0, 16, 50);

Note that with the window at this size, the thumb position can never go above 50 minus 16, or 34. You can determine how many lines are currently visible by dividing the current view size by the character height in pixels. When defining your own scrollbar behaviour, you will always need to recalculate the scrollbar settings when the window size changes. You could therefore put your scrollbar calculations and SetScrollbar call into a function named AdjustScrollbars, which can be called initially and also from your wxSizeEvent handler function.

Reimplemented in wxScrollBar.

virtual void wxWindow::SetScrollPos	(	int	orientation,
		int	pos,
		bool	refresh = `true`
	)		`[virtual]`

Sets the position of one of the built-in scrollbars.

Parameters:

orientation	Determines the scrollbar whose position is to be set. May be wxHORIZONTAL or wxVERTICAL.
pos	Position in scroll units.
refresh	true to redraw the scrollbar, false otherwise.

注意:: This function does not directly affect the contents of the window: it is up to the application to take note of scrollbar attributes and redraw contents accordingly.

void wxWindow::SetSize	(	int	x,
		int	y,
		int	width,
		int	height,
		int	sizeFlags = `wxSIZE_AUTO`
	)

ピクセル単位でウィンドウサイズを設定します。

Parameters:

x	Required x position in pixels, or wxDefaultCoord to indicate that the existing value should be used.
y	Required y position in pixels, or wxDefaultCoord to indicate that the existing value should be used.
width	Required width in pixels, or wxDefaultCoord to indicate that the existing value should be used.
height	Required height position in pixels, or wxDefaultCoord to indicate that the existing value should be used.
sizeFlags	Indicates the interpretation of other parameters. It is a bit list of the following: `wxSIZE_AUTO_WIDTH:` a wxDefaultCoord width value is taken to indicate a wxWidgets-supplied default width. `wxSIZE_AUTO_HEIGHT:` a wxDefaultCoord height value is taken to indicate a wxWidgets-supplied default height. `wxSIZE_AUTO:` wxDefaultCoord size values are taken to indicate a wxWidgets-supplied default size. `wxSIZE_USE_EXISTING:` existing dimensions should be used if wxDefaultCoord values are supplied. `wxSIZE_ALLOW_MINUS_ONE:` allow negative dimensions (i.e. value of wxDefaultCoord) to be interpreted as real dimensions, not default values. `wxSIZE_FORCE:` normally, if the position and the size of the window are already the same as the parameters of this function, nothing is done. but with this flag a window resize may be forced even in this case (supported in wx 2.6.2 and later and only implemented for MSW and ignored elsewhere currently).

注意:: This overload sets the position and optionally size, of the window. Parameters may be wxDefaultCoord to indicate either that a default should be supplied by wxWidgets, or that the current value of the dimension should be used.

virtual void wxWindow::SetSizeHints	(	const wxSize &	minSize,
		const wxSize &	maxSize = `wxDefaultSize`,
		const wxSize &	incSize = `wxDefaultSize`
	)		`[virtual]`

Use of this function for windows which are not toplevel windows (such as wxDialog or wxFrame) is discouraged.

Please use SetMinSize() and SetMaxSize() instead.

		int	maxW = `-1`,
		int	maxH = `-1`,
		int	incW = `-1`,

Sets the cached best size value.

参照:: GetBestSize()

Reimplemented in wxTopLevelWindow.

void wxWindow::SetSizer	(	wxSizer *	sizer,
		bool	deleteOld = `true`
	)

Sets the window to have the given layout sizer.

The window will then own the object, and will take care of its deletion. If an existing layout constraints object is already owned by the window, it will be deleted if the deleteOld parameter is true.

Note that this function will also call SetAutoLayout() implicitly with true parameter if the sizer is non-NULL and false otherwise so that the sizer will be effectively used to layout the window children whenever it is resized.

Parameters:

sizer	The sizer to set. Pass NULL to disassociate and conditionally delete the window's sizer. See below.
deleteOld	If true (the default), this will delete any pre-existing sizer. Pass false if you wish to handle deleting the old sizer yourself but remember to do it yourself in this case to avoid memory leaks.

注意:: SetSizer enables and disables Layout automatically.

void wxWindow::SetSizerAndFit	(	wxSizer *	sizer,
		bool	deleteOld = `true`
	)

This method calls SetSizer() and then wxSizer::SetSizeHints which sets the initial window size to the size needed to accommodate all sizer elements and sets the size hints which, if this window is a top level one, prevent the user from resizing it to be less than this minimal size.

virtual void wxWindow::SetThemeEnabled ( bool enable ) [virtual]

This function tells a window if it should use the system's "theme" code to draw the windows' background instead of its own background drawing code.

This does not always have any effect since the underlying platform obviously needs to support the notion of themes in user defined windows. One such platform is GTK+ where windows can have (very colourful) backgrounds defined by a user's selected theme.

Dialogs, notebook pages and the status bar have this flag set to true by default so that the default look and feel is simulated best.

void wxWindow::SetToolTip ( wxToolTip * tip )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void wxWindow::SetToolTip ( const wxString & tipString )

Attach a tooltip to the window.

wxToolTip pointer can be NULL in the overload taking the pointer, meaning to unset any existing tooltips; however UnsetToolTip() provides a more readable alternative to this operation.

Notice that these methods are always available, even if wxWidgets was compiled with wxUSE_TOOLTIPS set to 0, but don't do anything in this case.

参照:: GetToolTip(), wxToolTip

virtual bool wxWindow::SetTransparent ( wxByte alpha ) [virtual]

Set the transparency of the window.

If the system supports transparent windows, returns true, otherwise returns false and the window remains fully opaque. See also CanSetTransparent().

The parameter alpha is in the range 0..255 where 0 corresponds to a fully transparent window and 255 to the fully opaque one. The constants wxIMAGE_ALPHA_TRANSPARENT and wxIMAGE_ALPHA_OPAQUE can be used.

Reimplemented in wxTopLevelWindow.

virtual void wxWindow::SetValidator ( const wxValidator & validator ) [virtual]

Deletes the current validator (if any) and sets the window validator, having called wxValidator::Clone to create a new validator of this type.

void wxWindow::SetVirtualSize ( const wxSize & size )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void wxWindow::SetVirtualSize	(	int	width,

void wxWindow::SetWindowStyle ( long style )

See SetWindowStyleFlag() for more info.

Reimplemented in wxTreeCtrl.

virtual void wxWindow::SetWindowStyleFlag ( long style ) [virtual]

Sets the style of the window.

Please note that some styles cannot be changed after the window creation and that Refresh() might need to be called after changing the others for the change to take place immediately.

See Window styles for more information about flags.

参照:: GetWindowStyleFlag()

Reimplemented in wxAuiToolBar, and wxListCtrl.

void wxWindow::SetWindowVariant ( wxWindowVariant variant )

This function can be called under all platforms but only does anything under Mac OS X 10.3+ currently.

Under this system, each of the standard control can exist in several sizes which correspond to the elements of wxWindowVariant enum.

By default the controls use the normal size, of course, but this function can be used to change this.

virtual bool wxWindow::ShouldInheritColours ( ) const [virtual]

Return true from here to allow the colours of this window to be changed by InheritAttributes().

Returning false forbids inheriting them from the parent window.

The base class version returns false, but this method is overridden in wxControl where it returns true.

Reimplemented in wxRichTextCtrl.

virtual bool wxWindow::Show ( bool show = true ) [virtual]

ウィンドウの表示非表示を切り替えます。

You may need to call Raise() for a top level window if you want to bring it to top, although this is not needed if Show() is called immediately after the frame creation.

Notice that the default state of newly created top level windows is hidden (to allow you to create their contents without flicker) unlike for all the other, not derived from wxTopLevelWindow, windows that are by default created in the shown state.

Parameters:

show	If true displays the window. Otherwise, hides it.

Returns:: true if the window has been shown or hidden or false if nothing was done because it already was in the requested state.

参照:: IsShown(), Hide(), wxRadioBox::Show, wxShowEvent.

Reimplemented in wxDialog.

virtual bool wxWindow::ShowWithEffect	(	wxShowEffect	effect,
		unsigned int	timeout = `0`
	)		`[virtual]`

This function shows a window, like Show(), but using a special visual effect if possible.

Parameters:

effect	The effect to use.
timeout	The timeout parameter specifies the time of the animation, in milliseconds. If the default value of 0 is used, the default animation time for the current platform is used.

注:: Currently this function is only implemented in wxMSW and wxOSX (for wxTopLevelWindows only in Carbon version and for any kind of windows in Cocoa) and does the same thing as Show() in the other ports.

Since:: 2.9.0

参照:: HideWithEffect()

void wxWindow::Thaw ( )

Re-enables window updating after a previous call to Freeze().

To really thaw the control, it must be called exactly the same number of times as Freeze().

If the window has any children, they are recursively thawed too.

参照:: wxWindowUpdateLocker, Freeze(), IsFrozen()

bool wxWindow::ToggleWindowStyle ( int flag )

Turns the given flag on if it's currently turned off and vice versa.

This function cannot be used if the value of the flag is 0 (which is often the case for default flags).

Also, please notice that not all styles can be changed after the control creation.

Returns:: Returns true if the style was turned on by this function, false if it was switched off.

virtual bool wxWindow::TransferDataFromWindow ( ) [virtual]

子コントロールからバリデータで指定されたデータ領域へ値を転送します。

Returns false if a transfer failed.

If the window has wxWS_EX_VALIDATE_RECURSIVELY extra style flag set, the method will also call TransferDataFromWindow() of all child windows.

参照:: TransferDataToWindow(), wxValidator, Validate()

virtual bool wxWindow::TransferDataToWindow ( ) [virtual]

バリデータで指定されたデータ領域から子コントロールへ値を転送します。

virtual bool wxWindow::UnregisterHotKey ( int hotkeyId ) [virtual]

Unregisters a system wide hotkey.

Parameters:

hotkeyId Numeric identifier of the hotkey. Must be the same id that was passed to RegisterHotKey().

Returns:: true if the hotkey was unregistered successfully, false if the id was invalid.

注意:: This function is currently only implemented under MSW.

参照:: RegisterHotKey()

static void wxWindow::UnreserveControlId	(	wxWindowID	id,
		int	count = `1`
	)		`[static]`

Unreserve an ID or range of IDs that was reserved by NewControlId().

See Window IDs for more information.

Parameters:

id	The starting ID of the range of IDs to unreserve.
count	The number of sequential IDs to unreserve.

参照:: NewControlId(), wxIdManager, Window IDs

void wxWindow::UnsetToolTip ( )

Unset any existing tooltip.

Since:: 2.9.0

参照:: SetToolTip()

virtual void wxWindow::Update ( ) [virtual]

Calling this method immediately repaints the invalidated area of the window and all of its children recursively (this normally only happens when the flow of control returns to the event loop).

Notice that this function doesn't invalidate any area of the window so nothing happens if nothing has been invalidated (i.e. marked as requiring a redraw). Use Refresh() first if you want to immediately redraw the window unconditionally.

virtual void wxWindow::UpdateWindowUI ( long flags = wxUPDATE_UI_NONE ) [virtual]

This function sends one or more wxUpdateUIEvent to the window.

The particular implementation depends on the window; for example a wxToolBar will send an update UI event for each toolbar button, and a wxFrame will send an update UI event for each menubar menu item.

You can call this function from your application to ensure that your UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers are concerned). This may be necessary if you have called wxUpdateUIEvent::SetMode() or wxUpdateUIEvent::SetUpdateInterval() to limit the overhead that wxWidgets incurs by sending update UI events in idle time. flags should be a bitlist of one or more of the wxUpdateUI enumeration.

If you are calling this function from an OnInternalIdle or OnIdle function, make sure you pass the wxUPDATE_UI_FROMIDLE flag, since this tells the window to only update the UI elements that need to be updated in idle time. Some windows update their elements only when necessary, for example when a menu is about to be shown. The following is an example of how to call UpdateWindowUI from an idle function.

        void MyWindow::OnInternalIdle()
        {
            if (wxUpdateUIEvent::CanUpdate(this))
                UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
        }

virtual bool wxWindow::Validate ( ) [virtual]

バリデータを使用して子コントロールの現在の値を検証します。

If the window has wxWS_EX_VALIDATE_RECURSIVELY extra style flag set, the method will also call Validate() of all child windows.

Returns:: Returns false if any of the validations failed.

参照:: TransferDataFromWindow(), TransferDataToWindow(), wxValidator

virtual void wxWindow::WarpPointer	(	int	x,
		int	y
	)		`[virtual]`

Moves the pointer to the given position on the window.

注:: Apple Human Interface Guidelines forbid moving the mouse cursor programmatically so you should avoid using this function in Mac applications (and probably avoid using it under the other platforms without good reason as well).

Parameters:

x	The new x position for the cursor.
y	The new y position for the cursor.

virtual wxSize wxWindow::WindowToClientSize ( const wxSize & size ) const [virtual]

Converts window size size to corresponding client area size In other words, the returned value is what would GetClientSize() return if this window had given window size.

Components with wxDefaultCoord value are left unchanged.

Note that the conversion is not always exact, it assumes that non-client area doesn't change and so doesn't take into account things like menu bar (un)wrapping or (dis)appearance of the scrollbars.

Since:: 2.8.8
