wx.ContextHelpButton

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 object which itself generates a wxEVT_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 wx.OK, Cancel or similar buttons.
