Hi,I'm trying to do something that was discussed before in the Carbon lists : convert a HID keyboard usage to a unicode character, with the current modifierkeys applied, and using the system-wide selected keyboard layout. This technical note from Apple(http://developer.apple.com/technotes/tn2002/tn2056.html) details the file formats available for keyboard layouts, but there's no information about the wayto: - get info about the currently selected one- a method to convert a key code to a unicode char (parsing the whole XML file and doing the conversion by hand would be quite nasty, assuming that you evenknow how to do the first step: know what layout is to be used) Anyone knows how to do that ? Thanks for your help Fred
Use UCKeyTranslate(). http://developer.apple.com/documentation/Carbon/Conceptual/Supporting_Unicode_Input/sui_tasks/chapter_3_section_4.htmlNote that before Leopard, some keyboard layouts (French for example) does not have uchr ressources and uses the deprecated KCHR format instead. On Leopard, only some third party keyboard layouts use KCHR. In thoses cases, you will not able to use UCKeyTranslate(), but need to fallback to KeyTranslate() instead.
To retreive the current keyboard layout:- The new way (Leopard), Text Input Source Services ( http://developer.apple.com/documentation/TextFonts/Reference/TextInputSourcesReference/Reference/reference.html ). - The old way, Keyboard layout services ( http://developer.apple.com/documentation/Carbon/Reference/KeyboardLayoutServices/Reference/reference.html ).
