Title: METHOD OF UPDATING DISPLAY FRAMES WHILE PRESERVING INFORMATION ASSOCIATED THEREWITH
Abstract:
A method and apparatus for resizing or redrawing windows (58) without requiring additional server calls to supply the necessary information objects to dynamically update the content associated therewith. The invention does so by dividing a window into a plurality of frames (60 and 62), defining a reference window (56), and initializing the information objects when the reference window (56) is loaded into a client's computer (12). In this fashion, the information objects are associated with a subset of the plurality of memory address locations of the RAM (28) in the client's computer (12) with which the reference window (56) is associated. This prevents overwriting the memory address locations in which the information objects are located, because the lifetime of a reference window is as long as the same is open. Thus, information objects present in the memory address locations associated therewith are not considered freed-up by the browser (54) until the reference window (56) is closed.
