I have created a custom keyboard layout for my TouchStream keyboard with Azerty layout. What I did was copy the French KCHR resource to a new resource file, give it a separate resource ID (1112) and a new name, customized it with ResEdit then installed it in ~/Library/Keyboard Layouts/, cleaned the intl data caches, delogged/relogged then activated it.

While it works fine with most applications I found a carbon terminal app which is doing this:

long KCHRID = ::GetScriptVariable(smCurrentScript, smScriptKeys);
Handle KCHRHdl = ::GetResource('KCHR', KCHRID);

Then it uses the resource to call KeyTranslate().

I talked with the developer and it appears that the application is getting the correct KCHR resource ID but the GetResource call returns NULL.

The only solution I found so far is to copy/paste my KCHR resource into the application's resource file, but I think this may be a bug in Carbon.

I encountered this problem with my AutoPairs utility. The solution is not to use GetResource (on Jaguar and later), but rather something like this:

KeyboardLayoutRef layout = NULL;
OSStatus err = ::KLGetKeyboardLayoutWithIdentifier( kchrNum, &layout );
if (err == noErr)
{
err = ::KLGetKeyboardLayoutProperty( layout, kKLKCHRData, &kchrTable );
}
