Qt5 任务栏托盘功能实现

23333 有一阵子没写博客了,研究了挺长时间qt,学到任务栏托盘时简直无语,网上找得到的代码大多是废码,Qt5不支持或者本身就有毛病不能实现却被n多人转来转去的,甚是无语。

简单托盘功能以下在Qt5.5编译通过:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include 
#include //任务栏类
#include //菜单类
namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
private:
    QSystemTrayIcon *myTrayIcon;
    QMenu *myMenu;
    QAction *restoreWinAction;
    QAction *quitAction;
    void createMenu();
    Ui::MainWindow *ui;
private slots:
    void showNormal();
};

#endif // MAINWINDOW_H
MainWindow.h
#include "mainwindow.h"
#include 

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec();
}
Main.cpp
#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    //菜单
    createMenu();
    //判断系统是否支持托盘图标
    if(!QSystemTrayIcon::isSystemTrayAvailable())
    {
    return;
    }
    //实例QSystemTrayIcon
    myTrayIcon = new QSystemTrayIcon(this);
    //设置图标
    myTrayIcon->setIcon(QIcon(":/new/prefix1/abc"));
    //鼠标放托盘图标上提示信息
    myTrayIcon->setToolTip("Qt托盘图标功能");
    //设置消息
    myTrayIcon->showMessage("托盘","托盘管理",QSystemTrayIcon::Information,10000);
    //托盘菜单
    myTrayIcon->setContextMenu(myMenu);
    //显示
    myTrayIcon->show();

}

//绘制菜单
void MainWindow::createMenu()
{
restoreWinAction = new QAction("恢复(&R)",this);
quitAction = new QAction("退出(&Q)",this);
//恢复
connect(restoreWinAction,SIGNAL(triggered()),this,SLOT(showNormal()));
//退出
connect(quitAction,SIGNAL(triggered()),qApp,SLOT(quit()));
myMenu = new QMenu((QWidget*)QApplication::desktop());
//添加菜单
myMenu->addAction(restoreWinAction);
//分隔符
myMenu->addSeparator();
myMenu->addAction(quitAction);
}
//恢复
void MainWindow::showNormal()
{
this->show();
}

//点击最小化按钮隐藏
void QWidget::changeEvent(QEvent *e)
{
if((e->type()==QEvent::WindowStateChange)&&this->isMinimized())
{
    this->hide();
    }
}

MainWindow::~MainWindow()
{
    delete ui;
}
MainWindow.cpp

RC_FILE = 1.rc

所需图片要写在rc配置文件或者添加到工程资源中,.cto文件自备2333。
