As above, the only difference from the previous version is that it is addressed to the process of About and Exit menu events.
The event is a special property, a method pointer. He follows the "Hollywood Classes", "Don't call us, we will call you."
WxMessageDialog is a common dialog. It can be used as a About window, a prompt window, and so on.
EVT_ * Tell this is an event help function,
EVT_MENU tells the program that this function is processed by the menu,
EVT_MENU (Self, id_about, self.onabout "tells the program that the response is the menu item named ID_about presses the event.
