osx - How to change the Mac OS X Keyboard Layout programmatically? -

-

my qt app supports changing input language on linux , windows. want add support changing input language in mac osx, too.

unfortunately don't have information mac sdk. (my first , last work os x compiling qt , compiling app!)

i googling problem , found need use text input source services , found these codes:

tisinputsourceref isref; isref = tiscopycurrentkeyboardinputsource(); cfdataref uchr = (cfdataref)tisgetinputsourceproperty(isref, ktispropertyunicodekeylayoutdata);  uckeyboardlayout * keylayoutptr=(uckeyboardlayout*)cfdatagetbyteptr(uchr);

is keylayoutptr pointer current keyboard layout?

if answer above question "yes", should compare keylayoutptr?

in other words, how can check if current keyboard layout (for example) "english"? (or lang_english in win api or us in xlib.)

i think you'd pass isref tisgetinputsourceproperty, using key ktispropertyinputsourcelanguages, , check whether first language code in array "en" or that. don't know if return "en" or "en-us" etc.
