TGScrollBar and TGScrollBarElement
The classes in this file implement scrollbars. Scrollbars can be
either placed horizontal or vertical. A scrollbar contains three
TGScrollBarElements: The "head", "tail" and "slider". The head and
tail are fixed at either end and have the typical arrows in them.
The TGHScrollBar will generate the following event messages:
kC_HSCROLL, kSB_SLIDERPOS, position, 0
kC_HSCROLL, kSB_SLIDERTRACK, position, 0
The TGVScrollBar will generate the following event messages:
kC_VSCROLL, kSB_SLIDERPOS, position, 0
kC_VSCROLL, kSB_SLIDERTRACK, position, 0
~TGScrollBar()
Delete a scrollbar (either horizontal or vertical).
Bool_t HandleTimer(TTimer *t)
Handle repeat timer for horizontal or vertical scrollbar. Every time
timer times out we move slider.
Pixmap_t GetBckgndPixmap()
Static method returning scrollbar background pixmap.
Int_t GetScrollBarWidth()
Static method returning the scrollbar width.
