|api| Class API
===============


.. class:: GTKExpander(wx.Control)

   A :class:`GTKExpander` allows the user to hide or show its child by clicking on an expander
   triangle.

   .. method:: __init__(self, parent, id=wx.ID_ANY, label="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER)

      Default class constructor.
      
      :param `parent`: the :class:`GTKExpander` parent. Must not be ``None``;
      :param `id`: window identifier. A value of -1 indicates a default value;
      :param `label`: the expander text label;
      :param `pos`: the control position. A value of (-1, -1) indicates a default position,
       chosen by either the windowing system or wxPython, depending on platform;
      :param `size`: the control size. A value of (-1, -1) indicates a default size,
       chosen by either the windowing system or wxPython, depending on platform;
      :param `style`: the expander style.


   .. method:: DoGetBestSize(self)

      Gets the size which best suits the window: for a control, it would be the
      minimal size which doesn't truncate the control, for a panel - the same size
      as it would have after a call to `Fit()`.
      
      .. note:: Overridden from :class:`wx.Control`.


   .. method:: OnDrawGTKExpander(self, dc)

      Draws the :class:`GTKExpander` triangle.
      
      :param `dc`: an instance of :class:`wx.DC`.


   .. method:: OnDrawGTKText(self, dc)

      Draws the :class:`GTKExpander` text label.
      
      :param `dc`: an instance of :class:`wx.DC`.


   .. method:: OnSize(self, event)

      Handles the ``wx.EVT_SIZE`` event for :class:`GTKExpander`.
      
      :param `event`: a :class:`wx.SizeEvent` event to be processed.
