重写了closeEvent()函数我们点击关闭按钮时候执行了里面的closeEvent()函数hide()这样窗口就不会关闭了。托盘菜单的退出才是真的调用quit()关闭整个程序。直接在窗口类中增加以下代码
.h头文件增加 ///托盘相关开始添加成员及成员函数/
private:QMenu *trayMenu;//托盘菜单QSystemTrayIcon *tray;//托盘图标添加成员void InitTray();
protected:void closeEvent(QCloseEvent *event);// 重写申明void hideEvent(QHideEvent *event);// 重写申明
private slots:void iconActivated(QSystemTrayIcon::ActivationReason ireason);///托盘相关结束/
.cpp实现文件增加
