[X-snmp-devel] widget pixel

[David Sherwood]

How can I get a particular pixel value from a widget?
One solution could be to create an image from widget and than pick (x,y)
coordinate, but this is a very slow operation!

QPixmap pix(size());
bitBlt(pix, QPoint(0, 0), this, QRect(0, 0, width(), height()));
QImage img = pix.convertToImage();
QRgb value = img.pixel(x, y);

Some one know a faster way?
