+\func{void}{OnAssert}{\param{const wxChar }{*file}, \param{int }{line}, \param{const wxChar }{*msg}}
+
+This function is called when an assert failure occurs, i.e. the condition

+It is only called in debug mode (when {\tt \_\_WXDEBUG\_\_} is defined) as

+
+The base class version show the default assert failure dialog box proposing to
+the user to stop the program, continue or ignore all subsequent asserts.

-This event handler function is called (under Windows only) to allow the window to intercept keyboard events
-before they are processed by child windows.
+Called when command line parsing fails (i.e. an incorrect command line option
+was specified by the user). The default behaviour is to show the program usage
+text and abort the program.
-\wxheading{Parameters}
+Return {\tt TRUE} to continue normal execution or {\tt FALSE} to return
+{\tt FALSE} from \helpref{OnInit}{wxapponinit} thus terminating the program.

+Called after the command line had been successfully parsed. You may override

+set from the command line.
+
+Don't forget to call the base class version unless you want to suppress

-
-\func{void}{OnIdle}{\param{wxIdleEvent\& }{event}}
-
-Override this member function for any processing which needs to be done
-when the application is idle. You should call wxApp::OnIdle from your own function,
-since this forwards OnIdle events to windows and also performs garbage collection for
-windows whose destruction has been delayed.
-
-wxWindows' strategy for OnIdle processing is as follows. After pending user interface events for an
-application have all been processed, wxWindows sends an OnIdle event to the application object. wxApp::OnIdle itself
-sends an OnIdle event to each application window, allowing windows to do idle processing such as updating
-their appearance. If either wxApp::OnIdle or a window OnIdle function requested more time, by
-caling \helpref{wxIdleEvent::RequestMore}{wxidleeventrequestmore}, wxWindows will send another OnIdle
-event to the application object. This will occur in a loop until either a user event is found to be
-pending, or OnIdle requests no more time. Then all pending user events are processed until the system
-goes idle again, when OnIdle is called, and so on.

-\func{void}{OnEndSession}{\param{wxCloseEvent\& }{event}}
-
-This is an event handler function called when the operating system or GUI session is
-about to close down. The application has a chance to silently save information,
-and can optionally close itself.
-
-Use the EVT\_END\_SESSION event table macro to handle query end session events.
-
-The default handler calls \helpref{wxWindow::Close}{wxwindowclose} with a TRUE argument
-(forcing the application to close itself silently).
-
-\wxheading{Remarks}
-
-Under X, OnEndSession is called in response to the `die' event.
-
-Under Windows, OnEndSession is called in response to the WM\_ENDSESSION message.
