So I played with it briefly and I can get focusItem inside the applet 
(if I don't set focus policy to NoFocus) but the problem is that the 
code which maps layouts to windows/applications reside in keyboard 
daemon which knows nothing about keyboard applet etc. I could of course 
notify keyboard daemon from keyboard layout applet (e.g. via dbus) that 
it became active/inactive but that's quite ugly. More than that there 
might be other applets which don't want to steal "focus" from windows.
One such example is virtual keyboard applet - when it's clicked we most 
probably don't want to switch active window (to desktop) and change 
layout. So it would be nice to have some more generic solution.

I could put a workaround in keyboard daemon to exclude "keyboard layout" 
and "virtual keyboard" applets from stealing active window but I would 
need to know how to get "focused/active" applet from outside of applet. 
And any help here is appreciated.

Thanks
