* This is a special IO progress widget.

* it's purpose is to show a progress of the IO operation.
*
* Instead of creating a separate window, this is only a widget that can be
* easily embedded in a statusbar.
*
* Usage of StatusbarProgress is little different.
* This dialog will be a part of some application.
