Qt之自定义菜单（托盘菜单）

   继右键菜单之后，再次探讨托盘菜单。。。也许你对有些东西会感觉到莫名其妙，但大致思路不变，因为这些东西都是我根据实际项目所述。

   托盘菜单实现：通过QSystemTrayIcon+QMenu+QAction即可完美实现！

    实现方式：createActions用于创建菜单、菜单项,translateActions用于设置文本、实现多语化，translateAccount用于设置用户空间配额。

void TrayMenu::createActions()

{

    help_menu = new QMenu();

    //创建菜单项

    action_show = new QAction(this);

    action_quit = new QAction(this);

    action_login_home = new QAction(this);

    action_account = new QAction(this);

    action_user_space = new QAction(this);

    action_help = new QAction(this);

    action_about = new QAction(this);

    action_check_update = new QAction(this);

    action_setting = new QAction(this);

    help_menu->setIcon(QIcon(":/icon/help"));

    action_show->setIcon(QIcon(":/icon/open"));

    action_login_home->setIcon(QIcon(":/icon/home"));

    action_account->setIcon(QIcon(":/icon/user"));

    action_help->setIcon(QIcon(":/icon/help"));

    action_about->setIcon(QIcon(":/icon/about"));

    action_check_update->setIcon(QIcon(":/icon/update"));

    action_setting->setIcon(QIcon(":/icon/set"));

    action_quit->setIcon(QIcon(":/icon/quit"));

    //添加菜单项

    help_menu->addAction(action_about);

    help_menu->addAction(action_help);

    help_menu->addAction(action_check_update);

    this->addAction(action_show);

    this->addAction(action_login_home);

    this->addSeparator();

    this->addAction(action_account);

    this->addAction(action_user_space);

    this->addSeparator();

    this->addAction(action_setting);

    this->addMenu(help_menu);

    this->addAction(action_quit);

    //设置信号连接

    connect(action_show, SIGNAL(triggered(bool)), this, SIGNAL(showWidget()));

    connect(action_quit, SIGNAL(triggered(bool)), this, SIGNAL(logoutWidget()));

    connect(action_setting, SIGNAL(triggered(bool)), this, SIGNAL(setUp()));

    connect(action_about, SIGNAL(triggered(bool)), this, SIGNAL(aboutUs()));

    connect(action_login_home, SIGNAL(triggered(bool)), MenuAction::getInstance(), SLOT(openLoginHome()));

    connect(action_help, SIGNAL(triggered(bool)), MenuAction::getInstance(), SLOT(openHelpMe()));

QObject::connect(action_check_update, SIGNAL(triggered(bool)), MenuAction::getInstance(), SLOT(openCheckUpdate()));

}

void TrayMenu::translateActions()

{

    help_menu->setTitle(tr("help"));

    action_show->setText(tr("open"));

    action_quit->setText(tr("quit"));

    action_login_home->setText(tr("login home"));

    this->translateAccount();

    action_help->setText(tr("instruction"));

    action_about->setText(tr("about us"));

    action_check_update->setText(tr("check update"));

    action_setting->setText(tr("setting"));

}

void TrayMenu::translateAccount()

{

    action_user_space->setText(tr("use:") + use_space + QString("  ") + tr("total:") + total_space);

}

    托盘菜单项建立完成之后，在建立自己的托盘，包括：托盘图标、托盘提示信息等。

QSystemTrayIcon *system_tray = new QSystemTrayIcon();

//放在托盘提示信息、托盘图标

system_tray ->setToolTip(QString("我就是托盘"));
system_tray ->setIcon(QIcon(":/icon/login"));

TrayMenu *tray_menu = new TrayMenu();
system_tray->setContextMenu(tray_menu);

//点击托盘执行的事件
connect(system_tray , SIGNAL(activated(QSystemTrayIcon::ActivationReason)), this, SLOT(iconIsActived(QSystemTrayIcon::ActivationReason)));
     connect(tray_menu, SIGNAL(showWidget()), this, SLOT(showNormal()));

//显示托盘
system_tray->show();

//托盘显示提示信息

system_tray->showMessage(QString("托盘标题"), QString("托盘显示内容"));

效果如下：
