A customer is building his own widget subclass of core that looks something like a scroll bar. Whenever he does set values to change the position of the slider the window is erased before he gets the expose event causing an ugly flash and forcing him to rewrite more than should be required. Any ideas??

From the Intrinsics specification: "After calling all the set_values procedures, XtSetValues forces a redisplay by calling the Xlib XClearArea function if any of the set_values procedures returned True." Leo | |||||

He made his set values routine just return false and the same thing happens. I've asked him to send code, but is there anything in the core that could be interfering? Bruce | |||||

Only if the XtSetValues call is also changing something in the core record which would cause the intrinsics to redisplay the widget. Leo | |||||
