image\PROGRESSBUTTON.gif A rectangular bar that fills from left to right, like that shown when you copy files in the Windows Explorer. Use to provide visual feedback to the user about the progress of long operations or background processes.

Use rangeMax and rangeMin to set the range of movement. For example; to display percentage completed, set the rangeMin to 0 and the rangeMax to 100. Then as the process progresses, set the value to the approximate percentage completed.
