Widget Independence

In a typical application, a programmer produces code which creates and configures widgets and lastly enters a loop awaiting events. Thus, control of the application is handed over to the event dispatching mechanism of the Xt intrinsics. Events are dispatched to the widgets which perform the necessary actions, such as redrawing their windows for expose events, or resizing them when text labels change, etc. All this is performed by the widgets themselves, independently of the application programmer's code.
