<DIV>Hi,</DIV>
<DIV>Sorry, I didn't subscribe to the ml, I didn't find a link to do it from the project page.</DIV>
<DIV>Yes, the problem you describe is what I found. This behaviour (widgets become dark/black, whole screen becomes corrupted...) is typically due to a GDI leak. I ran this tool:</DIV>
<DIV><A href="http://msdn.microsoft.com/msdnmag/issues/03/01/GDILeaks/">http://msdn.microsoft.com/msdnmag/issues/03/01/GDILeaks/</A></DIV>
<DIV>and it appeared that it was a GDI pen leak (hundreds of pens no freed). So I looked for CreatePen and quickly found the guilty. Now it works fine (after removing this 2 lines).</DIV>
<DIV>There is another problem with erasing. I didn't find why it causes flickering. There are other problems too (mouse moves cause flickering too, etc...). I can't spend much time, for now, but later I will try to help you. I use Visual C++ 2003 and I was unable to create VC++ project files with qmake & .pro files. It is annoying because without the debuger & source code navigation I am lost :-) Is there a trick ?</DIV>
<DIV>What is the position of Trolltech about this port ? Can we use it without worry ?</DIV>
<DIV> </DIV>
<DIV>Regards.</DIV>

<DIV> Thanks for this. Can you explain exactly what problems you were seeing with<BR> painting?<BR> <BR> There is a long-standing problem with example programs such as scrollview<BR> (resize the window few time to see what I mean) where painting in the window<BR> and even the whole screen becomes corrupted. I think I've narrowed this down<BR> to the window hierachy but maybe you have some ideas that could help?<BR> <BR> Chris</DIV>
<DIV> Hi,<BR> This is my first post to this ml so excuse me if I am doing something wrong<BR> :-)<BR> I downloaded and tried qt-3 QT_WIN32_3_3_BRANCH. It quickly appeared that<BR> there was a problem with painting. I ran GDI leaks detection tools and found<BR> a problem with pens. The problem is in kernel/qpainter_win.cpp, line 2887:<BR> HPEN pen = CreatePen (PS_SOLID, 1, RGB (0, 0, 0));<BR> SelectObject (hdc, hpen);<BR> note the use of pen with CreatePen and hpen with SelectObject. I simply<BR> removed this 2 lines, and it works better now.<BR> I hope this helps.<BR></DIV><BR><BR><DIV>
