   yes, that's how i do it. i plan to put more examples in gtkNode/examples/*. 
you should of course feel free to check in your stuff...

   never tried to do that. if it can't be done through the API it's easy enough 
to write your own function for this; see GN_widget_get_attr in gtkNode_internal.c
   accessing data members is one of the biggest nuisances in the gtkNode 
approach. would be nice to be able to do something like 
ssnd(widget,'GN_get_attr',[attr])
   having generated GN_get_attr from the typedefs...

   cairo seems very interesting,
  but i don't know enough about it to predict when the future(tm) will be upon 
us. there is a GtkCairo widget (http://www.cairographics.org/GtkCairo), anybody 
know anything about that?
