well i didnt find any QT function so i have redirected output of the application but now the drawback is that it will hide non QT warnings to.

freopen( "/dev/null", "w", stdin );
freopen( "/dev/null", "w", stdout );
freopen( "/dev/null", "w", stderr );

Use QT_NO_WARNING_OUTPUT macro. See Qt Debug Documentation
