Re: Overriding system shortcuts in OSX

[Howard Bornstein]

I saw this when I tried to assign Cmd-H to a menu item. It simply did not
show up in the menu because Apple uses Cmd-H to hide the current
application.

Even assuming that Apple traps the Quit command and handles it, when I
assigned Cmd-Q with a multi-stack stand alone, it didn't work. I had to use
the solution proposed by Martin Koob:

Each of the substacks' scripts have a shutdownRequest handler but not a
'pass shutdownRequest' command.  This handler sends a prepareToQuit command
to the main card of the main stack.

substack stack script
---
on shutdownRequest
   send "preparetoquit" to card "main" of stack "mainstack"
end shutdownRequest
--
The main card of the main stack has the prepareToQuit handler which just has
a quit command.  This triggers the shutdownRequest handler in the main card.
This shutdownRequest handler has all of the code you want implemented before
quitting.  This handler has the 'pass shutdownRequest' command that allows
the application to quit.

Mainstack >card "main" script
---
on preparetoquit
quit
end preparetoquit

on shutdownRequest


pass shutdownRequest
end shutdownRequest

Re: Overriding system shortcuts in OSX

Oddly, when I have a Quit command in a custom menu, the option does not show 
up. I think this is because the Livecode menu has a Quit option already, which 
when using the browse tool will hilite when pressing CMD-Q, but will not 
actually quit. I have not tested this in a standalone yet.

I have no shutDownRequest commands in my scripts.

Apple has a list here:


You'll probably be able to recognize the ones that LC supports. The ones 
that are system-wide will override; for example, Cmd-M is going to 
minimize to the dock, Cmd-spacebar is going to give you Spotlight.

Re: Overriding system shortcuts in OSX

Do you know which system-wide shortcuts OS X traps? Cmd-H is the one I
found (Hide Apps) and Cmd-Q (for which there is a LC solution). I'm
wondering which other ones we might get stung on. Are you aware of a list
of these traps?

Re: Overriding system shortcuts in OSX

[J. Landman Gay]

OS X traps and responds to its own system-wide shortcuts and does not 
pass them on to the app, so LC won't know about those.


But Cmd-Q behaves slightly differently. OS X does notify the app so it 
can put up save dialogs or do other housekeeping. If Cmd-Q isn't 
working, then there is probably something in your app that prevents it 
from quitting, like pending messages, open drivers, not passing 
"shutdownRequest", etc.

It seems like this should be simple but I can't figure out how to get
around this problem. Is there a way to override system shortcuts in an OSX
standalone application?

Re: Overriding system shortcuts in OSX

After some difficulty, I've been able to get Quit to work, but the
command-Q part is handled by the system. What are you trying to do?

Is there a list of system shortcuts that can't be overridden? When you say
you want to make a quit hotkey, do you mean you want to assign command-Q to
a menu item?

It's my understanding that with OS X you cannot do this. I would like to make a 
quit hotkey so users can quit my application, but I cannot seem to get that to 
work.
