GTK use of function keys

["Norris, Kendall P." <Kendall Norris Honeywell com>]

I have a control screen with buttons representing the keyboard function
keys.  I want to allow the operator to click the screen button or press the
function key on the keyboard.  I have code working that detects the event
"key_press" but I am unable to detect any function keys.  The event->length
value is always 0 for these keys.  GIMP uses the "F1" key for help so I know
this is do-able.  What am I missing?
