Drawing non-rectangular buttons?

[shaheed]

Hi all,

Is it possible without major effort to draw non-rectangular buttons in KDE/Qt? 
Specifically, I want to draw something that approximates a normal keyboard 
button, in particular odd-shaped stuff like L-shaped "enter" keys.

I am aware of QWidget::setMask(), but if I understand correctly, it is a bit 
of a blunt instrument, and it is not clear to me if it would allow, for 
example, another button to intrude into the angle of the L-shaped "enter" key 
as on a real keyboard.

Any pointers appreciated.

Thanks, Shaheed
