Description
Situation happens when:
- system tray is created and shown
- new system tray menu is fully created (no further changes) and set as a new system tray menu.
In Qt >= 5.11 only "NewMenu" signal is sent, introduced in commit ff169e8859457188f94aed86368876ba5bab2e90. As you admit, it is not part of the standard.
Additional LayoutUpdated should be sent, for example in:
void QDBusTrayIcon::updateMenu(QPlatformMenu * menu)
// ...
m_menu->setRevision(oldMenu->revision());
m_menu->emitUpdated();
Unfortunately there is no API to get/set revision, it needs to be added in QDBusPlatformMenu. Without that, revision will start from 1 again and most probably LayoutUpdated will be ignored.
