1. A meta-thing. Used to stand for a real object in didactic examples (especially database tutorials). Legend has it that the original Widgets were holders for buggy whips. "But suppose the parts list for a Widget has 52 entries..." 2. [possibly evoking "window gadget"] In graphical user interfaces, a combination of a graphic symbol and some program code to perform a specific function. E.g. a scroll-bar or button. Windowing systems usually provide Widget libraries containing commonly used Widgets drawn in a certain style and with consistent behaviour. [Jargon File]
