Re: SendTextInputEvent returns eventNoHandledErr (-9874) with kEventTextInputUnicodeText type event

Alternatively, check out CGEventKeyboardSetUnicodestring() in CGEvent.h (available since Tiger). This flags the Unicode text so that when the key-focus process gets the CG event, instead of posting a raw key event to the Carbon event queue, a kEventTextInputUnicodeText event is dispatched instead via SendTextInputEvent() (with all the correct goodness)... seems more convenient if you're already using CGRemote.

The entries I found in the archives didn't answer my question... I'm hoping that this isn't too basic of a question or been answered previous. In any event, I'd definitely appreciate some guidance or better yet, an example! :)

I'm trying to have an application generate Unicode input to OSX apps like Character Palette and Ink do. Right now my app is using CGPostKeyboardEvent() and that's great when I know a key mapping...

But now I need to generate Unicode characters into the input stream which may not be in any current (or existing) Keyboard Layout. How does Character Palette do this? I'm under the assumption that I don't have to register a handler, and that the kEventTextInputUnicodeText event will be handled by a system handler, or isn't this at all the way Character Palette (et al) implement this. Hopefully I'm on the right track and I just have an embarrassing little coding error? Please advise.

Thanks,
Brad
