  16 To process an idle event, use this event handler macro to direct input to a member
  17 function that takes a wxIdleEvent argument.

  26 Idle events can be caught by the wxApp class, or by top-level window classes.

  43
  44 Tells wxWindows that more processing is required. This function can be called by an OnIdle
  45 handler for a window or window event handler to indicate that wxApp::OnIdle should
  46 forward the OnIdle event once more to the application windows. If no window calls this function
  47 during OnIdle, then the application will remain in a passive event loop (not calling OnIdle) until a
  48 new event is posted to the application by the windowing system.
