Re: Determining if a special input method is active - was Detecting double byte input

Lets just say I am hamstrung by some limitations related to QuickDraw 
and Carbon event handling.

I can work around them if I know when a special input method is active 
- I do not want nor need to write my own method.

i guess I could look for the command-space hot key, but that still 
would not tell me what the current input method is.

So to be specific the problem is... I need to know when a special input 
method is active..  is there something like a getCurrentInputMethod 
API?
