Hi There,
Thanks a lot Christophe for your support. I have now a complete setup supporting fr/latin9 keyboard !
I made a big step in my investigations, here is the summary:
1/ First I confirmed the keyboard settings in spiceqxl.xorg.conf are ignored.
-> In order to ensure the right keyboard is defined on Xorg server I used the following command:
$> /usr/bin/setxkbmap -model pc105 -layout fr -variant latin9
The -display parameter may be required.
2/ To grab the keycode form Xorg I used the following command:
$> showkey -k
Each time a key is pressed/released, The keycode is displayed
3/ To grab the keycode from HTML5 I used the following page:
http://www.cambiaresearch.com/articles/15/javascript-key-codes
4/ From there I've been able to rewrite utils.js and atKeynames.js and it works!
-> I have a strange behaviour with ^ key, but the AltGr + o/i/u does the stuff. ê is obtained with AltGr + $
Next step will be to clean up a bit my updates and make the keyboard selection possible.
I'll keep you posted.
thanks and regards,
