Window display system, window display method, program development support device, and server device

Abstract

There is provided a window display system and others capable of causing a single window to display a plurality of window structures while switching between them. An event processing program is correlated to a first window structure (15) and the first window structure is assigned to a basic window (14). When the event processing program (11A) is executed, a second window structure (16) is assigned to the basic window (14). By modifying or updating the basic window or by assigning the second window structure (16) to the basic window, a plot window (13) performs plotting. On the one plot window (13), the first and the second window structure (15, 16) are displayed by switching between them. Plotting of the plot window is caused by size modification, movement, color modification, modification of preceding and subsequent position, visualization, or invalidation of the plot area for the window.

Description

technical field [0001] The present invention relates to a window display system for displaying windows on a screen, and more particularly to a window display system for displaying windows under the management of a window management unit that manages multiple windows. Background technique [0002] Fig. 18 is a flowchart of a conventional window display system. In the conventional system, first, a window is generated or acquired (S101), and the structure of a window associated with an event handler is assigned to the generated window (S102). Thereafter, a window is drawn on the screen (S103), and finally, the window waits for an event to occur (S104). Then, when an event such as keyboard input or mouse operation occurs (S105a), the event is detected by the window management unit (S105b), and an event handler is executed (S106). When the event handler ends, the window simply returns to waiting for the event. [0003] Furthermore, "window structure (window structure)" refers ...
