+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.

\membersection{wxWindow::Close}\label{wxwindowclose}
-\func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}

The purpose of this call is to provide a safer way of destroying a window than using
the {\it delete} operator.
Applies to managed windows (wxFrame and wxDialog classes) only.
+{\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
+itself only hides the dialog.
