Hello, I'am trying to get the current keyboard layout in a Mac OS X 10.4 app. I need to detect when the current layout has changed (the user clicked the flag button). I have followed the code from https://nanohub.org/infrastructure/rappture-runtime/browser/trunk/tk8.4.19/macosx/tkMacOSXKeyEvent.c which seems ok for me and works perfectly in 10.5 & 10.6, but in 10.4, it only gets the system language and no change is detected. What's the matter with 10.4? Thank you in advance!
