As part of learning Coca from instead of always using carbon. I have
managed to put something other which seems to work quite well in the
time,
but now have a problem as is how to say I want to finish and quit this
application.
You might want to check out the terminate: method on NSApplication.
(Note: Be aware that this is quite different from the stop: method on
NSApplication, because the stop method just calls CFRunLoopStop() (or
whatever it is), which only exits from the current runloop, which may
not be the root one and thus may not result in control returning to
main(). Also not that you cannot call CFRunLoopStop() on a run loop
other than the one you are in; doing so results in Bad Things, which
in my case seems to be the whole system freezing some time soon
after!).
Any pointers ???, as I need to call this from a registered "C"
callback
mechanism within my application, as I register this callback with my
javascript functions, so when they want to quit, I need to quit out of
here,
fairly sharpness I immediate. I guess "exit() would work", but I think
telling the Coca framework I want to quit would be better so I could
then,
so something after in my main() proc.
Well, it's generally wise in a Cocoa app to not do anything in main
except run NSApplication. Having said that, when your app does
terminate (via the Quit command or any other method which results in
terminate: being called) control will return to main().
However, you may also want to look at the atexit() function; it allows
you to install a C function callback that is called whenever the
application exits, including when you call exit() explicitly (or any
other such exit function).
