[Gambas-user] Inhibit shutdown/logout/etc if unsaved files.

[Bruce Steers]

Seems qt does have an alternative as kate editor does it using qt session
manager
https://doc.qt.io/qt-5/qsessionmanager.html

i do not really understand kate code but i think this could be it's inhibit
routine. (or part of it)
https://invent.kde.org/utilities/kate/-/blob/master/apps/kate/main.cpp#L572

I found gedit worked on gnome2 and gnome3 variants but not on kde
kate on the other hand seems to inhibit on unsaved changes on all the above
so must be using a better method.
