QT 添加到系统托盘中

首先需要一个可被访问的图标

 参数图标添加

mainwindow.cpp

在这个文件中添加代码

 QIcon icon(":/Dm7.ico");

    systemTray = new QSystemTrayIcon(this);

    systemTray->setIcon(icon);

    systemTray->setToolTip("Test Radio Buttons");

    minimumAct = new QAction("Minimum Window", this);

    //Note the differences between hide() and showMinimized().

    connect(minimumAct, SIGNAL(triggered()), this, SLOT(hide()));

    maximumAct = new QAction("Maximum Window", this);

    connect(maximumAct, SIGNAL(triggered()), this, SLOT(showMaximized()));

    restoreAct = new QAction("Restore Window", this);

    connect(restoreAct, SIGNAL(triggered()), this, SLOT(showNormal()));

    quitAct = new QAction("Quit Application", this);

    connect(quitAct, SIGNAL(triggered()), qApp, SLOT(quit()));

    pContextMenu = new QMenu(this);

    pContextMenu->addAction(minimumAct);

    pContextMenu->addAction(maximumAct);

    pContextMenu->addAction(restoreAct);

    pContextMenu->addSeparator();

    pContextMenu->addAction(quitAct);

    systemTray->setContextMenu(pContextMenu);

    systemTray->show();

分别为图标添加代码函数

QSystemTrayIcon
功能组
QAction
以及枚举函数
Qmenu

在.h文件中添加变量

 QSystemTrayIcon*   systemTray;

    QAction*  minimumAct;

    QAction*  maximumAct;

    QAction*  restoreAct;

    QAction* quitAct;

  QMenu* pContextMenu;
