Qt将程序最小角化到系统托盘

#include "test.h"

#include "QPushButton"
#include <QSystemTrayIcon>

Test::Test(QWidget *parent)
    : QWidget(parent)
{
    ui.setupUi(this);

    QPushButton* btn = new QPushButton(QString::fromLocal8Bit("最小化"), this);
    connect(btn, &QPushButton::clicked, this, [=]() {
        this->hide();

        /* 最小化到系统托盘 */
        QSystemTrayIcon* mSysTrayIcon = new QSystemTrayIcon(this);
        mSysTrayIcon->setIcon(QIcon("logo.png"));
        mSysTrayIcon->setToolTip(QString::fromLocal8Bit("测试系统托盘图标"));
        mSysTrayIcon->show();       // 在系统托盘上显示此对象
        }); 
}
