A personal reply to my question sent me to the following link: <a href="http://stackoverflow.com/questions/23729704/change-osx-keyboard-layoutinput-source-programmatically-via-terminal-or-appl" target="_blank">http://stackoverflow.com/questions/23729704/change-osx-keyboard-layoutinput-source-programmatically-via-terminal-or-appl</a>.
I seem to have found a solution that worked using PyObjC.<br>
<br>
I'm currently using Python 3.3 installed via macports, and I
installed the appropriate ports for my setup (py33-pyobjc,
py33-pyobjc-cocoa).<br>
<br>
For my import statement:<br>
<blockquote>from AppKit import NSTextInputContext<br>
<br>
</blockquote>
To find the current keyboard being used:<br>
<blockquote>ic = NSTextInputContext.new()<br>
current_keyboard = ic.selectedKeyboardInputSource()<br>
<br>
</blockquote>
To list the currently available keyboards:<br>
<blockquote>keyboards = ic.keyboardInputSources()<br>
<br>
</blockquote>
To change the current keyboard (to 'Arabic', for example):<br>
<blockquote>ic.setValue_forKey_('com.apple.keylayout.Arabic',
'selectedKeyboardInputSource')<br>
</blockquote>
<br>
Now, that is the good news! This all worked great in my source code,
but as an app bundle (created with cx_Freeze 4.3.2) it wouldn't run
at all. I'll include the full error trace at the end of this email,
but the problems seem to start with the import of AppKit and end
with objc/_lazyimport.py. <br>
<br>
I'm not sure if this points to a 'bug' in objc or something else
which I've left out of my setup routine, but if anyone has any
ideas, I would be interested to hear from you.<br>
<br>
Best regards,<br>
