如何使我的小部件全屏？我尝试过这样的事情:

void MainWindow::SetFullScreen()
{
    // Make our window without panels
    this->setWindowFlags( Qt::FramelessWindowHint | Qt::Tool | Qt::WindowStaysOnTopHint );
    // Resize refer to desktop
    this->resize( QApplication::desktop()->size() );

    this->setFocusPolicy( Qt::StrongFocus );
    this->setAttribute(Qt::WA_QuitOnClose, true);

    qApp->processEvents();
    show();
    this->setFocus();
}

但是小部件不在系统面板之上.还有其他想法吗？
