qt app not responding in window XP

[ChrisW67]

its the problem with the os?? how can i solve this?? help me..

No, it's probably your code not returning to the Qt event loop... but that's the end of the help we can offer with no more information.

Try a simple program with a single widget and a few buttons.

is there any different in code for event looping for different OS??

I'm using stand alone QTCreator.. and i think (not so sure) any use of QEvent function is predefine..
where and how can i check and modified the code??

No, when ChrisW67 mentions the event loop he does not mean that you should manipulate QEvents. You need to make sure that your code does not get stuck in some slot for too long, thus preventing the event loop from running normally. What happens if you try basic GUI examples such as those from the documentation?
