Abstract: The preferred embodiments of the present invention provide a method and apparatus for managing and controlling the size and location of windows in a GUI-based computer system. Specifically, a window control mechanism is provided to enhance the basic functional features of a window in any windowing environment. By interacting with the window control mechanism, a user can quickly and easily relocate and resize a window without unnecessary mouse movement. In one preferred embodiment of the present invention, the user invokes the window control mechanism by positioning the cursor over the title bar of a window and using both buttons of a two button mouse. In another preferred embodiment of the present invention, the user invokes the window control mechanism by positioning the cursor over a window decoration and using both buttons of a two button mouse. Yet another preferred embodiment of the present invention allows the user to specify a keyboard keystroke combination to invoke the window control mechanism.
