Generally speaking fixing bug 1674749 (now bug 1671424) should be enough for most apps in the short term.
I'm reminded of how Microsoft handles this problem... WM_CLOSE: https://msdn.microsoft.com/en- us/library/windows/desktop/ms632617(v=vs.85).aspx WM_QUIT: https://msdn.microsoft.com/en-us/library/windows/desktop/ms632641(v=vs.85).aspx "The WM_QUIT message is not associated with a window and therefore will never be received through a window's window procedure." WM_POWERBROADCAST: https://msdn.microsoft.com/en- us/library/windows/desktop/aa373247(v=vs.85).aspx WM_ENDSESSION: https://msdn.microsoft.com/en- us/library/windows/desktop/aa376889(v=vs.85).aspx Each has a valid use case, and I don't think we can get away from similarly wanting a 'quit' message in Mir eventually. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1624407 Title: Add a 'quit' message that is app-wide, as opposed to mir_event_type_close_surface Status in Mir: Triaged Status in mir package in Ubuntu: Triaged Status in qtmir package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Bug description: Currently in unity8, when requesting to "Quit" a running application from the launcher, what happens is that qtmir goes through all its associated windows/surfaces, and closes them one by one. Supposedly, when the last window is closed, the application terminates itself (but this is not necessarily the case, see https://doc.qt.io/qt-5/qguiapplication.html#quitOnLastWindowClosed- prop). This prevents application authors from doing proper cleanup before the app is closed. For example in Qt, the QCoreApplication::aboutToQuit() signal is emitted only after all windows have been closed, so the application doesn’t get a chance to e.g. save the list of open windows (real use case for multi-window browser application which saves the current session). This is similar to unity7’s implementation by the way, but I think it’s wrong. Surely there must be a way (maybe toolkit-specific) to request an app to terminate itself (and fall back to closing all windows if not).
