[Touch-packages] [Bug 1624407] Re: Add a 'quit' message that is app-wide, as opposed to mir_event_type_close_surface
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.

I’m not sure how a fix for bug #1674749 would address the use case in the description: a multi-window application (such as web browser) wants to distinguish between: - please close all windows one by one without retaining state for them - please quit the app, and save the state for all windows and tabs in them -- 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.

[Touch-packages] [Bug 1624407] Re: Add a 'quit' message that is app-wide, as opposed to mir_event_type_close_surface
Clicking on a window's close button sends the app
mir_event_type_close_window. That's just an informational message that
apps are meant to act on (e.g. pop up a dialog if not terminate
themselves).
If you mean logout however, then I guess the right answer is that shells
should send mir_event_type_{close_window,quit_app} to all apps on
logout, and wait until the apps are no longer running (user responds to
dialogs from apps with unsaved work or some timeout expires).

Does Mir provide enough api to allow application ask user a question before shutdown?
