Abstract: A computer system including hardware and software, and a method of using the same to modify a interface or window without having to recompile. The window, or graphical user interface, is modifiable or extensible at runtime (post-compile) and might be displayed on the computer system's display. The method includes generating at least one runtime-modifiable component during runtime with the computer system's processor and providing a runtime modifiable configuration of the graphical user interface together with a generic loader function. A method of binding during runtime includes binding an element using a generic binding engine thus allowing to add, modify or drop elements in the post-compile adaptation of the system since both—the data source as well as the interface definition are stored in a way that they can be modified at runtime.
