本文介绍了一个使用 Qt 编写的程序中如何初始化系统托盘图标的过程。包括创建和配置托盘图标所需的动作、菜单以及托盘图标本身，并设置了相应的信号槽以响应用户的交互。

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()));
}
