Mechanism allowing separation of graphical display of object status from underlying data

摘要

A system that isolates all of the information that determines the look and feel of status displays of a GUI into one file is described. This file can be quickly edited to change the appearance when needed. In one embodiment, a user requests that an object border should be yellow instead of green for a particular situation. This modification is achieved without code recompilation, by editing a few lines in a file. Similarly, if another visual indicator needs to be added, file editing is all that is required. The application source code utilizes a class schema which defines the visual components of the GUI that should be modifiable file. A modifiable file comprising class instances corresponding to the class schema is read in and processed when the application is launched. Further changes require the application to be restarted to read in the modified file.
