ABSTRACT:
A method and apparatus for establishing an always-visible class of windows in a computer-implemented windowing environment is provided. A user may designate one or more windows as always-visible windows. If an always-visible window overlaps with a non-always-visible window, then the always-visible window is displayed on top of the non-always-visible window. Always-visible windows are prevented from overlapping with each other. Techniques are provided for implementing the always-visible window class in a manner that complies with the X Windows system. According to one technique, the override redirect attribute is used as a flag to designate which windows are always-visible windows. According to an alternative technique, a list of always-visible windows is maintained as a property attached to a root window.
