<DIV>Basically I need to set QIcon widget / QIcon loaded image to be transparent. So that the red color rectangle can be visible on top of QIcon Widget .</DIV>
<DIV>&nbsp;</DIV>
<DIV>I tried </DIV>
<DIV>&nbsp;</DIV>
<DIV>Approach(1): In QIcon paintEvent handler function.</DIV>
<DIV>&nbsp;</DIV>
<DIV>&nbsp;</DIV>
<DIV>&nbsp;&nbsp;&nbsp; QGfx * gfx = painter-&gt;internalGfx();<BR>&nbsp;&nbsp;&nbsp; unsigned int oldType = gfx-&gt;overlayTransparentType();<BR>&nbsp;&nbsp;&nbsp; gfx-&gt;setOverlayTransparentType(0);</DIV>
<DIV>&nbsp;</DIV>
<DIV>&nbsp;&nbsp;&nbsp; painter-&gt;drawPixmap (xPos, yPos, *pixmap);</DIV>
<DIV>&nbsp;</DIV>
<DIV>&nbsp;&nbsp;&nbsp; gfx-&gt;setOverlayTransparentType(oldType); <BR></DIV>
<DIV>
<DIV>Before drawing i called setOverlayTransparentType. But this doesn't solved the problem.</DIV>
<DIV>&nbsp;</DIV>
<DIV>Does anyone can help me&nbsp;on this ? Basically I could like to know How do I overlap QIcon loaded image &amp; Icon&nbsp;?</DIV></DIV>
<DIV align=left><FONT face=Verdana color=#0000ff size=2></FONT>&nbsp;</DIV>
