Description
Hiding the main window (e.g. for implementing "minimize to tray") breaks the global D-Bus menu on Ubuntu.
When starting the application, the menu is registered via D-Bus:
method call time=1486563446.131639 sender=:1.322 -> destination=com.canonical.AppMenu.Registrar serial=10 path=/com/canonical/AppMenu/Registrar; interface=com.canonical.AppMenu.Registrar; member=RegisterWindow uint32 81788932 object path "/MenuBar/1" signal time=1486563446.132247 sender=:1.19 -> destination=(null destination) serial=7645 path=/com/canonical/AppMenu/Registrar; interface=com.canonical.AppMenu.Registrar; member=WindowRegistered uint32 81788932 string ":1.322" object path "/MenuBar/1"
However, when the window is hidden (hide()), it is unregistered from the AppMenu registrar
signal time=1486563627.268775 sender=:1.19 -> destination=(null destination) serial=7742 path=/com/canonical/AppMenu/Registrar; interface=com.canonical.AppMenu.Registrar; member=WindowUnregistered uint32 81788932
and not re-registered once shown again.
Unfortunately, I can't call QDBusMenuBar::registerMenuBar() because it isn't exported to the public Qt library. My only options are therefore to either implement the D-Bus interface myself or disable native menus.
This issue does not happen on KDE Plasma 5.9, which also supports global menus, since hidden windows are not unregistered.
