I can't believe you linked me to google . I searched google in relation to qt but didn't get any answer that is why i asked.
Anyways, my question has been answered by qtcenter ( thankfully).
In the future, it's always a good thing if you spend some effort to your question before asking it. Don't just expect us to solve your issues at your whim. Always search your question first on major search engines, most likely someone else have the solutions and posted it somewhere.
