Scroll Bar Colors and Metrics
The system-defined color value, COLOR_SCROLLBAR, controls the color within a
scroll bar's shaft. Use the
GetSysColor function to determine the color of the shaft and the
SetSysColors function to set the color of the shaft. Note, however, that this change of
color affects all scroll bars in the system.
You can get the dimensions of the bitmaps that Windows uses in standard scroll
bars by calling the
GetSystemMetrics function. Following are the system metric values associated with scroll bars.
