[Qt-interest] QDockWidget, QGLWidget, QImage on intel chipset bug

[Nagella, S (Srikanth)]

Hi

 

I am trying to draw a QImage on QGLWidget using QPainter. QGLWidget  is
added as widget to QDockWidget. The code works fine on all graphics
cards except intel chipset. On intel graphics chipset the displayed
image is very badly pixelated.

If I replace the QDockWidget with a QMainWindow the final display is
correct.

 

    QPainter painter(this);

    painter.setRenderHint(QPainter::Antialiasing);

    QImage img("DisplayImage.bmp","BMP");

    painter.drawImage(0,0,img);

    painter.end();

 

Is there anything wrong with the dock widget?

Can anyone help please?

 

Thanks

Sri
