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.
+or dialog box using the window manager (X) or system menu (Windows). It can
+also be invoked by the application itself programmatically, for example by
+calling the \helpref{wxWindow::Close}{wxwindowclose} function.
You should check whether the application is forcing the deletion of the window
-using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}. If this is {\tt FALSE},
+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 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.

-Returns TRUE if you can veto a system shutdown or a window close event.
+Returns true if you can veto a system shutdown or a window close event.
Vetoing a window close event is not possible if the calling code wishes to
force the application to exit, and so this function must be called to check this.
\constfunc{bool}{GetLoggingOff}{\void}
-Returns TRUE if the user is logging off.
+Returns true if the user is logging off.

Call this from your event handler to veto a system shutdown or to signal
to the calling application that a window close did not happen.
You can only veto a shutdown if \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto} returns
-TRUE.
