Re: Get ascii code from GdkEventKey-Keyval

[Don Dudley <ddudley mybearcreek com>]

I don't know if you're using it, but if not you might install a key
snooper with gtk_key_snooper install().  If so, I assume this is your
handler function.
I did a similar thing, and you might have a look at the gdk function
 gdk_keyval_name() which converts a key value to a symbolic name,  or

 gdk_keyval_from_name(), which converts a key name to an actual key
value.

Reference manual is 
 developer.gnome.org/doc/API/2.0/gdk

Good Luck,
Don
