Hi If i understand you want change ui from other thread ? You can't do this Only from main Qt thread you can do it. If you want change widgets from other threads you have to create own Event like MyEvent and post it with method QApplication::postEvent from you thread and then handle this event in main Qt thread with method bool eventFilter ( QObject * watched, QEvent * event ) and do what you want. look at Qt documentation for more info...
