.. _wx.CollapsiblePane:

==========================================================================================================================================
|phoenix_title|  **wx.CollapsiblePane**
==========================================================================================================================================

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 :meth:`~wx.CollapsiblePane.GetPane`  function to access the pane and add your controls inside it (i.e., use the returned pointer from :meth:`~wx.CollapsiblePane.GetPane`  as the parent for the controls which must go in the pane, **not**  the :ref:`wx.CollapsiblePane`  itself!). 

Note that when using this control inside a sizer, you will usually want to call :meth:`wx.Window.Layout`   whenever its size changes due to the pane being opened or closed, in order to adjust the positions of the neighbouring controls, for example: 

::

        collpane = wx.CollapsiblePane(self, wx.ID_ANY, "Details:")

        # add the pane with a zero proportion value to the 'sz' sizer which contains it
        sz.Add(collpane, 0, wx.GROW | wx.ALL, 5)

        # now add a test label in the collapsible pane using a sizer to layout it:
        win = collpane.GetPane()
        paneSz = wx.BoxSizer(wx.VERTICAL)
        paneSz.Add(wx.StaticText(win, wx.ID_ANY, "test!"), 1, wx.GROW | wx.ALL, 2)
        win.SetSizer(paneSz)
        paneSz.SetSizeHints(win)



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





.. _CollapsiblePane-styles:

|styles| Window Styles
================================

This class supports the following styles: 

  

- ``wx.CP_DEFAULT_STYLE``: The default style. It includes ``wx.TAB_TRAVERSAL`` and ``wx.BORDER_NONE``.  
- ``wx.CP_NO_TLW_RESIZE``: By default :ref:`wx.CollapsiblePane`  resizes the top level window containing it when its own size changes. This allows easily implementing dialogs containing an optionally shown part, for example, and so is the default behaviour but can be inconvenient in some specific cases – 








.. _CollapsiblePane-events:

|events| Events Emitted by this Class
=====================================

Handlers bound for the following event types will receive one of the :ref:`wx.CollapsiblePaneEvent`:ref:`wx.NavigationKeyEvent` parameters.


- EVT_COLLAPSIBLEPANE_CHANGED: The user expanded or collapsed the collapsible pane.  
- EVT_NAVIGATION_KEY: Process a navigation key event.
