"""This event handler is called with the given event when Qt receives
a window close request for a top-level widget from the window
system.
By default, the event is accepted and the widget is
closed. You can reimplement this function to change the way
the widget responds to window close requests. For example, you
can prevent the window from closing by calling ignore() on all
events.
In other words: If you do not want your widget to be hidden,
or want some special handling, you should reimplement the
event handler and ignore() the event.
