// Event table: connect the events to the handler functions to process them

// The event tables connect the wxWidgets events with the functions (event

// simple menu events like this the static method is much simpler.
// The reason why the menuitems and tools are given the same name in the
// XRC file, is that both a tool (a toolbar item) and a menuitem are designed
// to fire the same kind of event (an EVT_MENU) and thus I give them the same
// ID name to help new users emphasize this point which is often overlooked
// when starting out with wxWidgets.
