Hi Olivier,

thanks for your reply, reading through the ``Writing your own widgets''
chapter of the tutorial and through the sources of some widgets in the
gtk+ source tree has put me in the same direction.
Probably I'll try both possibilities this weekend. Learning an API is
diving into it ;o)

Thanks again and regards
Frank
