 This event class contains information about window and session close events.
 
+The handler function for EVT\_CLOSE is called when the user has tried to close a a frame
+or dialog box using the window manager (X) or system menu (Windows). It is
+called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
+that the application can also invoke the handler programmatically.
+
+You should check whether the application is forcing the deletion of the window
+using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}. If this is {\tt FALSE},
+you {\it must} destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
+If the return value is TRUE, it is up to you whether you respond by destroying the window.
+
+If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
+let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
+to return {\tt TRUE} or {\tt FALSE} depending on whether the close instruction was honoured or not.
