Description
A tray application developed with Qt 5.12 exhibits abnormal behavior when running on Ubuntu 18.x (18.04) and Ubuntu 16.x (16.04), with erratic mouse click events.
Symptoms:
1) Tray single-click event is unresponsive.
2) Tray double-click is required to trigger QSystemTrayIcon::trigger.
3) QSystemTrayIcon::trigger event cannot be triggered.
The event signal handling code is as follows:
void SystemTrayIcon::onActivated(QSystemTrayIcon::ActivationReason reason)
{
switch (reason) {
case QSystemTrayIcon::unknown:
vdi_info("QSystemTrayIcon::Unknown");
break;
case QSystemTrayIcon::doubleclick:
vdi_info("QSystemTrayIcon::DoubleClick");
emit trigger(DoubleClick);
break;
case QSystemTrayIcon::trigger:
vdi_info("QSystemTrayIcon::Trigger");
emit trigger(OneClick);
break;
case QSystemTrayIcon::context:
vdi_info("QSystemTrayIcon::Context");
emit trigger(RightClick);
break;
default:
vdi_info("QSystemTrayIcon::%d", reason);
break;
}
}
connect(m_sysTray, &QSystemTrayIcon::activated, this, &SystemTrayIcon::onActivated);
