Hi guys I have this problem

Qt Code:
  1. int main(int argc, char *argv[])
  2. {
  3. QApplication a(argc, argv);
  4. application w;
  5.  
  6. QPixmap pixmap(":/img/splash.jpg");
  7. QSplashScreen *splash = new QSplashScreen(pixmap);
  8. splash->showFullScreen();
  9.  
  10. QTimer::singleShot(2500, splash, SLOT(close()));
  11. QTimer::singleShot(2500, &w, SLOT(showFullScreen()));
  12.  
  13. return a.exec();
  14. }
To copy to clipboard, switch view to plain text mode 

The splashscreen is not being displayed at full screen, there is the bottom bar which is in front of it...
what am I doing wrong?
