Qt加载托盘图标

需要加载托盘图标时：

    QIcon icon(":/img/res/music.png");    QSystemTrayIcon * systemTray = new QSystemTrayIcon(this);    systemTray->setIcon(icon);    systemTray->setToolTip("双击打开");    systemTray->show();                    //显示托盘图标    //关联托盘信号   connect(systemTray,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,SLOT(tray_notify(QSystemTrayIcon::ActivationReason)));

托盘信号的槽函数：

void TestWidget::tray_notify(const QSystemTrayIcon::ActivationReason & reason){    switch(reason)    {    case QSystemTrayIcon::Context:        //右键        qDebug()<<"QSystemTrayIcon::Context";        break;    case QSystemTrayIcon::DoubleClick:     //双击        systemTray->hide();                //隐藏托盘        qDebug()<<"QSystemTrayIcon::DoubleClick";        break;    case QSystemTrayIcon::Trigger:          //单击        qDebug()<<"QSystemTrayIcon::Trigger";        break;    case QSystemTrayIcon::MiddleClick:      //中键单击        qDebug()<<"QSystemTrayIcon::MiddleClick";    default:                                                qDebug()<<"QSystemTrayIcon::Unknow";        break;    }}
