/* Get the size of the screen */

	QDesktopWidget *desktop = QApplication::desktop();
	int screenWidth = desktop->width();
	int screenHeight = desktop->height();

/* create the main window and resize */

	QWidget *mainWin = new Mainwindow();
	mainWin->resize(screenWidth, screenHeight);

/* go to full screen */
	mainWin->setWindowState(mainWin->windowState() | 				 
Qt::WindowFullScreen);
