TSRVScrollBar is a scrollbar, which is used to scroll the contents of a window, form, or control.
TSRVScrollBar = class(TScrollBar)
This is a skinnable version of TScrollBar. These scrollbars are used in TSRichViewEdit.
If skins are not defined, the scrollbar appearance depends on SRVControlStyle property:
srvcsSimple (if RVControlsPainter.Theme = rvctPaleBlue):
If this control is not inserted in TSRichViewEdit control, we recommend to assign True to its DoubleBuffered property to prevent flickering.
