18// TGProgressBar, TGHProgressBar and TGVProgressBar //
19// //
20// The classes in this file implement progress bars. Progress bars can //
21// be used to show progress of tasks taking more then a few seconds. //
22// TGProgressBar is an abstract base class, use either TGHProgressBar //
23// or TGVProgressBar. TGHProgressBar can in addition show the position //
24// as text in the bar. //
