One of the newest additions to SVN enables the Cmd-Q keystroke under OS X, which shuts down DOSBox immediately. Cmd-Q is the "quit" keystroke for all OS X applications.

However, under every other OS X application that I have tried, Cmd-Q only shuts down the application immediately if there is no unsaved document open in the application. If an unsaved document is open, then Cmd-Q brings up a dialog asking "Do you want to Quit?" or some similar message.

As implemented in SVN, Cmd-Q shuts down DOSBox immediately without any dialog. (At least that's way it seems to work for me.) For my own application (which is NOT game-related) this is slightly dangerous, because it means that a user can lose work. I think it might be dangerous for gaming also, since someone who presses Cmd-Q by mistake might lose all the progress made in a game during the current session.

I know I can build my own application without the lines of code that enable Cmd-Q. But is there any hope that it might be changed to bring up a "Do you really want to quit" dialog instead of shutting down immediately? I think that this might be preferred by users who run games under DOSBox in OS X.

The behaviour is similar to our ctrl-f9 quit key, although that one can be unmapped, but there is no dos game that wants to use the Cmd key.

Very true. I was thinking about the possibility that someone playing a game might hit the Cmd-Q key by mistake when trying to exit the game cleanly by pressing Ctrl-Q (if there really ARE any games that use Ctrl-Q to exit), and then not having any way to avoid the immediate shutdown. As you say, Ctrl-F9 can be unmapped to avoid anything like that.

I won't bother you any longer about this, but I thought it was at least worth asking the question.

I think those games that exit by ctrl-q exit right away too.
Osx users should know better than to use cmd-q. Apps that aren't text editors that create docs or something like that exit directly with cmd-q as well.

Sounds reasonable to me. I think I may have wasted bandwidth on this one. Cmd-Q is certainly a useful addition.
