U++

When designing GUIs, a lot of small frames and spacing is used for aesthetics.

You often create a "border" of indents around some GUI element to highlight it. The border I'm designing is broken by TabCtrl's scrollbar.

With TabBar::AddFrameToScroolBar:

void AddFrameToScroolBar(CtrlFrame& fr)                 { sc.AddFrame(fr); }

one can shift the scrollbar around and add borders to it.

Very minor issue, the difference is only a few pixels, but aesthetics is aesthetics...
