Hi wysota!
I have installed qt4.2.2 on my system and is able to see the output for Example program. It looks good. Thanks!!!!

Now I should first start porting qt3.x.x to qt4.x.x. What I'l do is first take a sample helloWorld program from qt3 and port it to qt4. Then see what changes I need to make to port qt3 to qt4.

Have a great day!!!!
