Detailed Description

A collapsible pane is a container with an embedded button-like control which can be used by the user to collapse or expand the pane's contents.

Once constructed you should use the GetPane() function to access the pane and add your controls inside it (i.e. use the returned pointer from GetPane() as parent for the controls which must go in the pane, not the wxCollapsiblePane itself!).

Note that because of its nature of control which can dynamically (and drastically) change its size at run-time under user-input, when putting wxCollapsiblePane inside a wxSizer you should be careful to add it with a proportion value of zero; this is because otherwise all other windows with non-null proportion values will automatically resize each time the user expands or collapse the pane window usually resulting in a weird, flickering effect.

Usage sample:

    wxCollapsiblePane *collpane = new wxCollapsiblePane(this, wxID_ANY, "Details:");

    // add the pane with a zero proportion value to the 'sz' sizer which contains it
    sz->Add(collpane, 0, wxGROW|wxALL, 5);

    // now add a test label in the collapsible pane using a sizer to layout it:
    wxWindow *win = collpane->GetPane();
    wxSizer *paneSz = new wxBoxSizer(wxVERTICAL);
    paneSz->Add(new wxStaticText(win, wxID_ANY, "test!"), 1, wxGROW|wxALL, 2);
    win->SetSizer(paneSz);
    paneSz->SetSizeHints(win);

It is only available if wxUSE_COLLPANE is set to 1 (the default).

Styles

This class supports the following styles:

• wxCP_DEFAULT_STYLE:
  The default style. It includes wxTAB_TRAVERSAL and wxBORDER_NONE.
• wxCP_NO_TLW_RESIZE:
  By default wxCollapsiblePane resizes the top level window containing it when its own size changes. This allows to easily implement dialogs containing an optionally shown part, for example, and so is the default behaviour but can be inconvenient in some specific cases -- use this flag to disable this automatic parent resizing then.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxCollapsiblePaneEvent& event) or void handlerFuncName(wxNavigationKeyEvent& event)

Event macros for events emitted by this class:

• EVT_COLLAPSIBLEPANE_CHANGED(id, func):
  The user expanded or collapsed the collapsible pane.
• EVT_NAVIGATION_KEY(func):
  Process a navigation key event.

Member Function Documentation

virtual void wxCollapsiblePane::Collapse

(

bool

collapse = true

)

[virtual]

Collapses or expands the pane window.

bool wxCollapsiblePane::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxString &	label,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxCP_DEFAULT_STYLE,
		const wxValidator &	validator = wxDefaultValidator,
		const wxString &	name = wxCollapsiblePaneNameStr
	)

Parameters:

parent	Parent window, must not be non-NULL.
id	The identifier for the control.
label	The initial label shown in the button which allows the user to expand or collapse the pane window.
pos	Initial position.
size	Initial size.
style	The window style, see wxCP_* flags.
validator	Validator which can be used for additional date checks.
name	Control name.

Returns:

true if the control was successfully created or false if creation failed.

void wxCollapsiblePane::Expand

(

)

Same as calling Collapse(false).

virtual wxWindow* wxCollapsiblePane::GetPane

(

)

const [virtual]

Returns a pointer to the pane window.

Add controls to the returned wxWindow to make them collapsible.

virtual bool wxCollapsiblePane::IsCollapsed

(

)

const [virtual]

Returns true if the pane window is currently hidden.

bool wxCollapsiblePane::IsExpanded

(

)

const

Returns true if the pane window is currently shown.
