Thanks!

allthough, if i instantiante treeValue i get the following message at run-time 
everytime the code is run:
** (<unknown>:3887): CRITICAL **: file value.c: line 35 
(gtksharp_value_get_value_type): assertion `G_IS_VALUE (value)' failed

but if i don't instantiate treeValue in that example (out parameters don't 
necessarily have to be instantiated before they are passed along to a 
method), it works perfectly and without any messages.

thanks for helping me out :)

kind regards,
