Drawing part of Pixmap onto circular region of widget.

Perdrix

As Qt doesn't seem to support (by and large) drawing onto a non-rectangular area, how do I go about copying a portion of a Pixmap onto a circular area of my widget?

I'm guessing that this might involve QPainterPath ...

Thanks, David

Hi
It its possible using a mask/region/brush depending on what you really like.

In any case for plain drawing then maybe
QRegion region (0, 0, w,h, QRegion::Ellipse);
is what you want and then use it for clipping.

QRegion region (0, 0, w,h, QRegion::Ellipse); is what you want and then use it for clipping.

Works nicely (once I got the sums right for selecting the correct source rectangle).
