How to get one pixel from QWidget?

[TomNow99]

Hi,

I would like to get one pixel's color from myWidget. I find something like "render". I would like to get pixel (30,30) from myWidget. So I try:

QPixmap pixmap(1,1); // because I would like to get only one pixel
render(&pixmap, QPoint(30,30)); 
QColor color=pixmap.toImage().pixelColor(0,0); 

I get very strange R G B:

15 52 240
15 52 240
15 52 240
15 52 240
15 52 240
15 52 240
14 83 208
14 90 144
14 83 208

I don't change myWidget's color.
