已经绑定了啊，请教一下：

``` c++

void MainWindow::InitSystemTray()
{
// 1. 初始化托盘
m_systemTray = new QSystemTrayIcon(this);
m_systemTray->setIcon(QIcon(":/resource/background/app.png"));

// 2. 初始化托盘菜单
m_trayMenu = new QMenu(this);
m_trayMenu->addAction("我在线上");
m_trayMenu->addAction("离线");
m_trayMenu->addSeparator();
m_trayMenu->addAction("显示主面板");
m_trayMenu->addSeparator();
m_trayMenu->addAction("退出");

// 3. 将托盘菜单添加进托盘
m_systemTray->setContextMenu(m_trayMenu);
m_systemTray->show();

// 4. 关联菜单项对应的槽函数
connect(m_systemTray, SIGNAL(activated(QSystemTrayIcon::ActivationReason)), this, SLOT(SltTrayClicked(QSystemTrayIcon::ActivationReason)));
connect(m_trayMenu, SIGNAL(triggered(QAction*)), this, SLOT(SltTrayMenuClicked(QAction*)));

}
