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

It is the duty of the application to define a suitable event handler, and

signal to the calling code if it does not destroy the window, by calling
\helpref{wxCloseEvent::Veto}{wxcloseeventveto}. Calling this provides useful information
to the calling code.
Your application can either use \helpref{wxWindow::Close}{wxwindowclose} event just as
the framework does, or it can call \helpref{wxWindow::Destroy}{wxwindowdestroy} directly.

that we definitely want to delete the frame and it cannot be vetoed.
The advantage of using Close instead of Destroy is that it will call any clean-up code
defined by the EVT\_CLOSE handler; for example it may close a document contained in
a window after first asking the user whether the work should be saved. Close can be vetoed
-by this process (return FALSE), whereas Destroy definitely destroys the window.

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