    I am trying to create a css generator like the one here: "http://www.colorzilla.com/gradient-editor/":http://www.colorzilla.com/gradient-editor/ . The preview pane dynamically changes according to the options selected. I want to create something of that sort. I'm trying to use QPainter to draw QRects, but unable to apply gradients. And how to apply border radius to it? And finally, I should be able to convert the preview to an image. Please help me out.
    Thanks in advance!

      this code draws a rounded rect (2px radius) filled with a gradient (linear from left to right) using QPainter:
      @
      QLinearGradient gradient(0, 0, 1, 0);
      gradient.setCoordinateMode( QGradient::ObjectBoundingMode );
      gradient.setColorAt( 0, color1 );
      gradient.setColorAt( 1, color2 );

      QPainter p(..);
      p.setPen( ... ); //rect border
      p.setBrush( gradient );
      p.drawRoundedRect( rect, 2, 2 );
      @
