wxWindow is the base class for all windows. Any children of the window will be deleted
automatically by the destructor before the window itself is deleted.
-Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
-help text. These must not be called by a user program and are documented only for illustration.
-On several platforms, only a few of these handlers are actually written (they are not always
-needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
-the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
-platform can implement its native behaviour or just ignore the event if nothing needs to be
-done.

-\func{virtual bool}{Close}{\param{bool}{ force = {\tt FALSE}}}
+\func{bool}{Close}{\param{bool}{ force = {\tt false}}}
-The purpose of this call is to provide a safer way of destroying a window than using
-the {\it delete} operator.
+This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
+handler usually tries to close the window. It doesn't close the window itself,
+however.
\wxheading{Parameters}
-\docparam{force}{{\tt FALSE} if the window's close handler should be able to veto the destruction
-of this window, {\tt TRUE} if it cannot.}
+\docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
+of this window, {\tt true} if it cannot.}
\wxheading{Remarks}
-Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
-choose whether to destroy the window.
+Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
+an opportunity for the window to choose whether to destroy the window.
+Usually it is only used with the top level windows (wxFrame and wxDialog
+classes) as the others are not supposed to have any special OnClose() logic.
The close handler should check whether the window is being deleted forcibly,
-using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should

+{\it Note} that calling Close does not guarantee that the window will be
+destroyed; but it provides a way to simulate a manual close of a window, which
+may or may not be implemented by destroying the window. The default
+implementation of wxDialog::OnCloseWindow does not necessarily delete the
+dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
+the appropriate button event handler and may do anything at all.
