Abstract
Abstract A system and method is provided that causes an animation sequence and underlying background process to be in step such that the motion of the animation is coordinated with the painting of the display by the underlying process. A mechanism is used to adjust the thread priority of the animation thread. When the animation is starting, the priority of the animation threads is set to BELOW -- NORMAL priority. The animation process is then implemented. Subsequently, the animation threads are set back to NORMAL priority. Because the priority of the animation threads is below normal the other, contending processes will react more quickly (due to their higher priority) during the animation process. This will cause the other processes to update (paint) their client areas more quickly. Each change to another processes client area will cause an update to that area, since that other process will have a higher priority relative to the animation sequence.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
109 words
A multitasking data processing system that displays an animated image, generated by a first process, superimposed on at least one other image, generated by a second process, comprising: means for determining whether said animated image will cause a previously obscured area of said other image to become visible; and means for assigning a first priority value to said first process which is relatively lower than a second priority value assigned to said second process; wherein said data processing system executes said second process at a higher relative priority than said first process such that said other image is available for display when said animated image exposes said other image.
Claim 2
Dependent Claim
109 words
A multitasking data processing system that displays an animated image, generated by a first process, superimposed on at least one other image, generated by a second process, comprising: means for determining whether said animated image will cause a previously obscured area of said other image to become visible; and means for assigning a first priority value to said first process which is relatively lower than a second priority value assigned to said second process; wherein said data processing system executes said second process at a higher relative priority than said first process such that said other image is available for display when said animated image exposes said other image.
Claim 3
Dependent Claim
35 words
A system according to claim 1 wherein said means for determining comprises means for storing, before display of said animated image, an inital priority level for each of said first process and said second process.
Claim 4
Dependent Claim
24 words
A system according to claim 2 further comprising means for painting said animated image on a display screen of said multitasking data processing system.
Claim 5
