Description
===========

Instances of this class may be used to add a question mark button that when pressed, puts the application 
into context-help mode. It does this by creating a `wx.ContextHelp <wx.ContextHelp.html>`_ object which 
itself generates a ``wx.EVT_HELP`` event when the user clicks on a window.

On Windows, you may add a question-mark icon to a dialog by use of the ``wx.DIALOG_EX_CONTEXTHELP`` extra style, 
but on other platforms you will have to add a button explicitly, usually next to ``OK``, ``Cancel`` or similar buttons.
