Abstract
A method and apparatus for re-drawing a transparent window on at least one display device of a computer based system having a central processor and a memory is disclosed. Having a transparent window and an underlying second window, it is determined whether the underlying second window is active. If the underlying second window is active, the transparent window is hidden. The underlying second window is re-drawn and the transparent window is shown. Otherwise, the transparent window is maintained.
Claims10
A method for re-drawing a transparent window and a first object of a first application program with an underlying second window of a second application program on at least one display device of a computer-based system having a central processor, memory and said display device, said method comprising the steps of:
- determining whether said underlying second window is active;
- if said underlying second window is active, hiding said transparent window and said first object of said first application program;
- yielding said first application program's central processor's time to said second application program to allow said second application program to re-draw its window and object;
- showing at least a portion of said transparent window and said first object;
- else
- maintaining said transparent window and said first object.
A system for re-drawing a transparent window and a first object of a first application program with an underlying second window of a second application program on at least one display device, said system comprising:
- means for maintaining said transparent window if said underlying second window is inactive;
- means for hiding said transparent window and said first object of said first application program if said underlying second window is active;
- means for yielding said application program's central processor's time to said second application program to allow said second application program to re-draw its window and object if said underlying second window is active;
- and
- means for showing at least a portion of said transparent window and said first object if said underlying second window is active.
