My Qt Application shows the QSystemTrayIcon on fresh install but after reboot or logout/login I see the QSystemTrayIcon disappears from UI on startup.
I am seeing this issue on 20.04 and 22.04. 18.04 works no issues.
My implementation is straightforward. This function is called on initialization:
// Create tray and setup tray icon
void MyApp::createTrayIcon()
{
QString trayNotConn = TRAY_IMG;
m_pTrayIconMenu = new QMenu(this);
m_pTrayImage = new QPixmap(trayNotConn);
m_pTrayIcon = new QSystemTrayIcon(this);
QIcon icon(*m_pTrayImage);
m_pTrayIcon->setIcon(icon);
setWindowIcon(icon);
m_pTrayIcon->show();
connect(m_pTrayIcon, SIGNAL(activated(QSystemTrayIcon::ActivationReason)),
this, SLOT(onActivated(QSystemTrayIcon::ActivationReason)));
}
I'm aware that Gnome has stopped supporting system tray icons and I'm using Top Icons Extension on 20.04. I still see the issue on reboot inspite of this.
