Busybar class derives from Area class and creates a widget which shows an animation indicating that the application is currently in a busy state. This animation, however, just shows activity but no progress. If you would like to visualize progress, use Progressbar class instead. See Progressbar class for details.
Once you've created an object of Busybar class, you have to call Busybar.Move repeatedly
to move the animation. This can be achieved by setting up an interval timer using Hollywood's
SetInterval() function.
