catch current XkbLayout

[gustavo halperin <ggh.develop@gmail.com>]

Hello

I'm using  "Enlightenment Window Manager"  without KDE  and without Gnome. My XFree86 is 
configured with three keyboard layouts:
    
Option         
"XkbLayout"     "es,il,us"
    
Option         
"XkbOptions"    "grp:shift_toggle"
My question is : when ever the keyboard Layout changes, how can I catch
that such a change occurred and how can I catch the layout type. 
This in order
to write an applet that will display a different layout for every language

Thank you in advance
