A panel presented on a computer display consists of related text or graphic elements that are placed on that display in a fashion determined by an application programmer. Some of these elements are conditional; that is, they appear on the display only if certain criteria are met. Others are not conditional, and they appear on the panel whenever that panel is displayed. A mechanism is described by which all elements are placed optimally on the display. This mechanism is time efficient in that placement occurs at the time the panel is defined (compile-time) and not at the time the panel is displayed by the application (run-time). An alternative is also described which is space efficient instead, but still provides diagnostic information at compile-time.
