Ok, so how come the difference in X11 and Apple's window manager?
In X, if I instruct a window to be minimised, it is - immediately. The
app running in the window gets a signal, and can do appropriate stuff
if it needs to, but otherwise doesn't do anything.
With Apple windows, if an app freezes with it's window open, trying to
minimise the window makes no difference. This is the same behaviour on
Windows, IINM.
I think I've been misunderstanding your posts. By Apple's window
manager, I thought you were referring to the windows manager that Apple
has built for it's X11 implementation, (quartz-wm), as opposed to other
X11 windows managers. However, this post leads me to believe that you
are referring to the non-X11 native OS X windows interface.
Right. I just didn't know what to call it since they all have strange
unfamiliar (to me) names.
I have had apps under X11 that would freeze and not respond to a
resize/minimize request. I've intentionally built one that would not
minimize or resize. (The customer insisted.) I've had some apps
freezes in a device driver could not respond to any event, even an
attempted kill -9 of the app. I don't know much about how OS X handles
native windows; however, it may be a problem in a different layer if a
window hangs and can't be minimized, killed, etc.
Right, I understand that an app can freeze and not response to anything
(including kill -9). My point is that with Apple's native OS X interface,
there's nothing you can do about it.
For example, I occasionally have QuickTime player freeze when in full
screen mode. When that happens, I can't do anything apart from reset the
machine. I suppose I could log in via the network and do a proper reboot,
but I don't have easy access to another machine from which to log in.
On my X11 machines, I can simply instruct the window manager to minimise
the window (alt-f9 or something) or push it down in the window stack
(alt-f3 or something) and then open a terminal or other application to
deal with it.
