wx.ContextHelp

Inheritance diagram for wx.ContextHelp:



Description

This class changes the cursor to a query and puts the application into a ‘context-sensitive help mode’. When the user left-clicks on a window within the specified window, a wx.EVT_HELP event is sent to that control, and the application may respond to it by popping up some help.

There are a couple of ways to invoke this behaviour implicitly:

  • Use the wx.DIALOG_EX_CONTEXTHELP style for a dialog (Windows only). This will put a question mark in the titlebar, and Windows will put the application into context-sensitive help mode automatically, with further programming.
  • Create a wx.ContextHelpButton, whose predefined behaviour is to create a context help object. Normally you will write your application so that this button is only added to a dialog for non-Windows platforms (use wx.DIALOG_EX_CONTEXTHELP on Windows).

Note that on Mac OS X, the cursor does not change when in context-sensitive help mode.
