When the user clicks on the system close button or system close command,
-in a frame or a dialog, wxWindows calls \helpref{wxWindow::Close}{wxwindowclose}. This
+in a frame or a dialog, wxWidgets calls \helpref{wxWindow::Close}{wxwindowclose}. This
in turn generates an EVT\_CLOSE event: see \helpref{wxCloseEvent}{wxcloseevent}.
It is the duty of the application to define a suitable event handler, and
The wxCloseEvent handler should only call \helpref{wxWindow::Destroy}{wxwindowdestroy} to
delete the window, and not use the {\bf delete} operator. This is because
-for some window classes, wxWindows delays actual deletion of the window until all events have been processed,

since otherwise there is the danger that events will be sent to a non-existent window.
As reinforced in the next section, calling Close does not guarantee that the window

The default close event handler for wxFrame destroys the frame using Destroy().
