QSystemTrayIcon activated signal workaround

anshah

It is well documented that the QSystemTrayIcon::activated signal doesn't work on Ubuntu Unity. In order to get around this I am using the QSystemTrayIcon context menu's QMenu::aboutToShow signal to capture mouse clicks.

// Create tray and setup tray icon
void MyClass::createTrayIcon()
{
    m_pTrayIconMenu = new QMenu(this);
    m_pTrayImage    = new QPixmap(MY_IMAGE);
    m_pTrayIcon     = new QSystemTrayIcon(this);

    m_pTrayIcon->setContextMenu(m_pTrayIconMenu);

    QIcon icon(*m_pTrayImage);
    m_pTrayIcon->setIcon(icon);
    setWindowIcon(icon);
    m_pTrayIcon->show();

    connect(m_pTrayIconMenu, SIGNAL(aboutToShow()),
                    this,                              SLOT(onActivated()));
}

Though this is working fine except the context menu is showing still. Is there any way to suppress the context menu from showing at all? I realize I'm piggybacking the QMenu::aboutToShow signal because the QSystemTrayIcon::activated signal does not go out in Unity, but if you guys have any ideas that would be great! I see this on all Unity versions Ubuntu 14.04+. I do not see this issue on GNome.

Hi
tried on win 10 but it does not show the menu.
I was wondering if we subclass QMenu and override
paintEvent and draws nothing if something would still show?
I dont have unity to test on.
