void Shutdown::initTrayIcon()    {             //创建并设置动作         minAction = new QAction(this);         minAction->setIcon(QIcon(":/icons/min.bmp"));         connect(minAction,SIGNAL(triggered()),this,SLOT(hide()));

  

    restoreAction = new QAction(this);        restoreAction->setIcon(QIcon(":/icons/restore.bmp"));         connect(restoreAction,SIGNAL(triggered()),this,SLOT(showNormal()));

  

    aboutAction = new QAction(this);        aboutAction->setIcon(QIcon(":/icons/shutdown03.jpg"));         connect(aboutAction,SIGNAL(triggered()),this,SLOT(showAboutDlg()));

  

    quitAction = new QAction(this);        quitAction->setIcon(QIcon(":/icons/quit.bmp"));         connect(quitAction,SIGNAL(triggered()),qApp,SLOT(quit()));

  

    //创建托盘图标菜单并添加动作        trayIconMenu = new QMenu(this);         trayIconMenu->addAction(restoreAction);         trayIconMenu->addAction(minAction);         trayIconMenu->addSeparator();         trayIconMenu->addAction(aboutAction);         trayIconMenu->addSeparator();         trayIconMenu->addAction(quitAction);

  

    //创建并设置托盘图标        trayIcon = new QSystemTrayIcon(this);         trayIcon->setContextMenu(trayIconMenu);         trayIcon->setIcon(QIcon(":/icons/shutdown01.png"));

  

    //显示系统托盘图标        trayIcon->show();

  

    connect(trayIcon,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,                SLOT(trayIconActivated(QSystemTrayIcon::ActivationReason)));         connect(trayIcon, SIGNAL(messageClicked()), this, SLOT(trayIconMsgClicked()));     }
