QT中实现托盘

添加一个槽函数用于响应在托盘图标及托盘菜单上的鼠标点击操作

#include "mainwindow.h"

#include "ui_mainwindow.h"

#include <QSystemTrayIcon>

#include <QIcon>

#include <QCloseEvent>

#include <QMenu>

MainWindow::MainWindow(QWidget *parent) :

    QMainWindow(parent),

    ui(new Ui::MainWindow)

{

    ui->setupUi(this);

    QMenu * menu = new QMenu;

    menu->addAction("&Open",this,SLOT(slotmenuopen()),QKeySequence::Open);

    menu->addAction("&Exit",this,SLOT(close()),QKeySequence::Close);

    QSystemTrayIcon *trayicon = new QSystemTrayIcon;

    trayicon->setIcon(QIcon(":/new/bing.ico"));

    trayicon->setToolTip("this test!");

    trayicon->setContextMenu(menu);//添加头盘菜单

    trayicon->show();

    trayicon->showMessage("this test","test",QSystemTrayIcon::Information,5000);

    connect(trayicon,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),

            this,SLOT(slotactivated(QSystemTrayIcon::ActivationReason)));

}

MainWindow::~MainWindow()

{

    delete ui;

}

void MainWindow::closeEvent(QCloseEvent *e)

{

//    e->ignore();

//    this->hide();

}

//添加一个槽函数用于响应在托盘图标及托盘菜单上的鼠标点击操作

void MainWindow::slotactivated(QSystemTrayIcon::ActivationReason reasom)

{

    if(reasom == QSystemTrayIcon::Trigger)

    {

        if(this->isHidden())

            this->show();

        else

            this->hide();

    }

}

void MainWindow::slotmenuopen()

{

    this->show();

}
