wxRibbonArtProvider Class Reference

Detailed Description

wxRibbonArtProvider is responsible for drawing all the components of the ribbon interface.

This allows a ribbon bar to have a pluggable look-and-feel, while retaining the same underlying behaviour. As a single art provider is used for all ribbon components, a ribbon bar usually has a consistent (though unique) appearance.

By default, a wxRibbonBar uses an instance of this class called wxRibbonDefaultArtProvider, which resolves to wxRibbonAUIArtProvider, wxRibbonMSWArtProvider, or wxRibbonOSXArtProvider - whichever is most appropriate to the current platform. These art providers are all slightly configurable with regard to colours and fonts, but for larger modifications, you can derive from one of these classes, or write a completely new art provider class. Call wxRibbonBar::SetArtProvider to change the art provider being used.

virtual wxRibbonArtProvider* wxRibbonArtProvider::Clone

(

)

const [pure virtual]

Create a new art provider which is a clone of this one.

virtual void wxRibbonArtProvider::DrawButtonBarBackground	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background for a wxRibbonButtonBar control.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto (which will typically be the button bar itself, though this is not guaranteed).
rect	The rectangle within which to draw.

virtual void wxRibbonArtProvider::DrawButtonBarButton	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect,
		wxRibbonButtonBarButtonKind	kind,
		long	state,
		const wxString &	label,
		const wxBitmap &	bitmap_large,
		const wxBitmap &	bitmap_small
	)		[pure virtual]

Draw a single button for a wxRibbonButtonBar control.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto.
rect	The rectangle within which to draw. The size of this rectangle will be a size previously returned by GetButtonBarButtonSize(), and the rectangle will be entirely within a rectangle on the same device context previously painted with DrawButtonBarBackground().
kind	The kind of button to draw (normal, dropdown or hybrid).
state	Combination of a size flag and state flags from the wxRibbonButtonBarButtonState enumeration.
label	The label of the button.
bitmap_large	The large bitmap of the button (or the large disabled bitmap when wxRIBBON_BUTTONBAR_BUTTON_DISABLED is set in state).
bitmap_small	The small bitmap of the button (or the small disabled bitmap when wxRIBBON_BUTTONBAR_BUTTON_DISABLED is set in state).

virtual void wxRibbonArtProvider::DrawGalleryBackground	(	wxDC &	dc,
		wxRibbonGallery *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background and chrome for a wxRibbonGallery control.

This should draw the border, background, scroll buttons, extension button, and any other UI elements which are not attached to a specific gallery item.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto, which is always the gallery whose background and chrome is being drawn. Attributes used during drawing like the gallery hover state and individual button states can be queried from this parameter by wxRibbonGallery::IsHovered(), wxRibbonGallery::GetExtensionButtonState(), wxRibbonGallery::GetUpButtonState(), and wxRibbonGallery::GetDownButtonState().
rect	The rectangle within which to draw. This rectangle is the entire area of the gallery control, not just the client rectangle.

virtual void wxRibbonArtProvider::DrawGalleryItemBackground	(	wxDC &	dc,
		wxRibbonGallery *	wnd,
		const wxRect &	rect,
		wxRibbonGalleryItem *	item
	)		[pure virtual]

Draw the background of a single item in a wxRibbonGallery control.

This is painted on top of a gallery background, and behind the items bitmap. Unlike DrawButtonBarButton() and DrawTool(), it is not expected to draw the item bitmap - that is done by the gallery control itself.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto, which is always the gallery which contains the item being drawn.
rect	The rectangle within which to draw. The size of this rectangle will be the size of the item's bitmap, expanded by gallery item padding values (wxRIBBON_ART_GALLERY_BITMAP_PADDING_LEFT_SIZE, wxRIBBON_ART_GALLERY_BITMAP_PADDING_RIGHT_SIZE, wxRIBBON_ART_GALLERY_BITMAP_PADDING_TOP_SIZE, and wxRIBBON_ART_GALLERY_BITMAP_PADDING_BOTTOM_SIZE). The drawing rectangle will be entirely within a rectangle on the same device context previously painted with DrawGalleryBackground().
item	The item whose background is being painted. Typically the background will vary if the item is hovered, active, or selected; wxRibbonGallery::GetSelection(), wxRibbonGallery::GetActiveItem(), and wxRibbonGallery::GetHoveredItem() can be called to test if the given item is in one of these states.

virtual void wxRibbonArtProvider::DrawMinimisedPanel	(	wxDC &	dc,
		wxRibbonPanel *	wnd,
		const wxRect &	rect,
		wxBitmap &	bitmap
	)		[pure virtual]

Draw a minimised ribbon panel.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto, which is always the panel which is minimised. The panel label can be obtained from this window. The minimised icon obtained from querying the window may not be the size requested by GetMinimisedPanelMinimumSize() - the bitmap argument contains the icon in the requested size.
rect	The rectangle within which to draw. The size of the rectangle will be at least the size returned by GetMinimisedPanelMinimumSize().
bitmap	A copy of the panel's minimised bitmap rescaled to the size returned by GetMinimisedPanelMinimumSize().

virtual void wxRibbonArtProvider::DrawPageBackground	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background of a ribbon page.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto (which is commonly the wxRibbonPage whose background is being drawn, but doesn't have to be).
rect	The rectangle within which to draw.

参照:

GetPageBackgroundRedrawArea

virtual void wxRibbonArtProvider::DrawPanelBackground	(	wxDC &	dc,
		wxRibbonPanel *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background and chrome for a ribbon panel.

This should draw the border, background, label, and any other items of a panel which are outside the client area of a panel.

Note that when a panel is minimised, this function is not called - only DrawMinimisedPanel() is called, so a background should be explicitly painted by that if required.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto, which is always the panel whose background and chrome is being drawn. The panel label and other panel attributes can be obtained by querying this.
rect	The rectangle within which to draw.

virtual void wxRibbonArtProvider::DrawScrollButton	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect,
		long	style
	)		[pure virtual]

Draw a ribbon-style scroll button.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto.
rect	The rectangle within which to draw. The size of this rectangle will be at least the size returned by GetScrollButtonMinimumSize() for a scroll button with the same style. For tab scroll buttons, this rectangle will be entirely within a rectangle on the same device context previously painted with DrawTabCtrlBackground(), but this is not guaranteed for other types of button (for example, page scroll buttons will not be painted on an area previously painted with DrawPageBackground()).
style	A combination of flags from wxRibbonScrollButtonStyle, including a direction, a for flag, and one or more states.

virtual void wxRibbonArtProvider::DrawTab	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRibbonPageTabInfo &	tab
	)		[pure virtual]

Draw a single tab in the tab region of a ribbon bar.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto (not the wxRibbonPage associated with the tab being drawn).
tab	The rectangle within which to draw, and also the tab label, icon, and state (active and/or hovered). The drawing rectangle will be entirely within a rectangle on the same device context previously painted with DrawTabCtrlBackground(). The rectangle's width will be at least the minimum value returned by GetBarTabWidth(), and height will be the value returned by GetTabCtrlHeight().

virtual void wxRibbonArtProvider::DrawTabCtrlBackground	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background of the tab region of a ribbon bar.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto.
rect	The rectangle within which to draw.

virtual void wxRibbonArtProvider::DrawTabSeparator	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect,
		double	visibility
	)		[pure virtual]

Draw a separator between two tabs in a ribbon bar.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto.
rect	The rectangle within which to draw, which will be entirely within a rectangle on the same device context previously painted with DrawTabCtrlBackground().
visibility	The opacity with which to draw the separator. Values are in the range [0, 1], with 0 being totally transparent, and 1 being totally opaque.

virtual void wxRibbonArtProvider::DrawTool	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect,
		const wxBitmap &	bitmap,
		wxRibbonButtonKind	kind,
		long	state
	)		[pure virtual]

Draw a single tool (for a wxRibbonToolBar control).

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto. In most cases this will be a wxRibbonToolBar, but it doesn't have to be.
rect	The rectangle within which to draw. The size of this rectangle will at least the size returned by GetToolSize(), and the height of it will be equal for all tools within the same group. The rectangle will be entirely within a rectangle on the same device context previously painted with DrawToolGroupBackground().
bitmap	The bitmap to use as the tool's foreground. If the tool is a hybrid or dropdown tool, then the foreground should also contain a standard dropdown button.
kind	The kind of tool to draw (normal, dropdown, or hybrid).
state	A combination of wxRibbonToolBarToolState flags giving the state of the tool and it's relative position within a tool group.

virtual void wxRibbonArtProvider::DrawToolBarBackground	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background for a wxRibbonToolBar control.

Parameters:

dc	The device context to draw onto.
wnd	The which is being drawn onto. In most cases this will be a wxRibbonToolBar, but it doesn't have to be.
rect	The rectangle within which to draw. Some of this rectangle will later be drawn over using DrawToolGroupBackground() and DrawTool(), but not all of it will (unless there is only a single group of tools).

virtual void wxRibbonArtProvider::DrawToolGroupBackground	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect
	)		[pure virtual]

Draw the background for a group of tools on a wxRibbonToolBar control.

Parameters:

dc	The device context to draw onto.
wnd	The window which is being drawn onto. In most cases this will be a wxRibbonToolBar, but it doesn't have to be.
rect	The rectangle within which to draw. This rectangle is a union of the individual tools' rectangles. As there are no gaps between tools, this rectangle will be painted over exactly once by calls to DrawTool(). The group background could therefore be painted by DrawTool(), though it can be conceptually easier and more efficient to draw it all at once here. The rectangle will be entirely within a rectangle on the same device context previously painted with DrawToolBarBackground().

virtual void wxRibbonArtProvider::GetBarTabWidth	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxString &	label,
		const wxBitmap &	bitmap,
		int *	ideal,
		int *	small_begin_need_separator,
		int *	small_must_have_separator,
		int *	minimum
	)		[pure virtual]

Calculate the ideal and minimum width (in pixels) of a tab in a ribbon bar.

Parameters:

	dc	A device context to use when one is required for size calculations.
	wnd	The window onto which the tab will eventually be drawn.
	label	The tab's label (or wxEmptyString if it has none).
	bitmap	The tab's icon (or wxNullBitmap if it has none).
[out]	ideal	The ideal width (in pixels) of the tab.
[out]	small_begin_need_separator	A size less than the ideal size, at which a tab separator should begin to be drawn (i.e. drawn, but still fairly transparent).
[out]	small_must_have_separator	A size less than the small_begin_need_separator size, at which a tab separator must be drawn (i.e. drawn at full opacity).
[out]	minimum	A size less than the small_must_have_separator size, and greater than or equal to zero, which is the minimum pixel width for the tab.

virtual bool wxRibbonArtProvider::GetButtonBarButtonSize	(	wxDC &	dc,
		wxWindow *	wnd,
		wxRibbonButtonBarButtonKind	kind,
		wxRibbonButtonBarButtonState	size,
		const wxString &	label,
		wxSize	bitmap_size_large,
		wxSize	bitmap_size_small,
		wxSize *	button_size,
		wxRect *	normal_region,
		wxRect *	dropdown_region
	)		[pure virtual]

Calculate the size of a button within a wxRibbonButtonBar.

Parameters:

wxRibbonArtProvider::GetColour()

virtual wxColour wxRibbonArtProvider::GetColour

(

int

id

)

const [pure virtual]

Get the value of a certain colour setting.

id can be one of the colour values of wxRibbonArtSetting.

virtual void wxRibbonArtProvider::GetColourScheme	(	wxColour *	primary,
		wxColour *	secondary,
		wxColour *	tertiary
	)		const [pure virtual]

Get the current colour scheme.

Returns three colours such that if SetColourScheme() were called with them, the colour scheme would be restored to what it was when SetColourScheme() was last called. In practice, this usually means that the returned values are the three colours given in the last call to SetColourScheme(), however if SetColourScheme() performs an idempotent operation upon the colours it is given (like clamping a component of the colour), then the returned values may not be the three colours given in the last call to SetColourScheme(). If SetColourScheme() has not been called, then the returned values should result in a colour scheme similar to, if not identical to, the default colours of the art provider. Note that if SetColour() is called, then GetColourScheme() does not try and return a colour scheme similar to colours being used - it's return values are dependent upon the last values given to SetColourScheme(), as described above.

Parameters:

[out]	primary	Pointer to a location to store the primary colour, or NULL.
[out]	secondary	Pointer to a location to store the secondary colour, or NULL.
[out]	tertiary	Pointer to a location to store the tertiary colour, or NULL.
