>
>
> I'm trying to develop a button-like control which can be
> rotated, and I need
> to be able to stack a number of these controls next to each
> other like a
> sort of rotated toolbar.
>
> The Paint method uses Canvas.Polygon to draw the rotated
> rectangular button,
> but the overall control window is being erased and is
> overwriting adjacent
> controls. How can I draw this non-rectangular control without touching
> anything outside the area of my polygon?
>
> TRotateButton is derived from TCustomControl.

> Thanks in advance.
