event-driven
A kind of program, such as a graphical user interface, with a main loop which just waits for events to occur. Each event has an associated handler which is passed the details of the event, e.g. mouse button 3 pressed at position (355, 990).
For example, X window system and most Visual Basic application programs are event-driven. See also callback.Last updated: 2000-02-09
