   thank u! i've got it working now - that's really great. my mistake was
 that i expanded the tree_item before attaching a subtree to it. 
   but there's a problem - it works only with gtk_tree_item_expand(). when
 i change it to gtk_tree_item_collapse() i get 'pluses' in the little
 boxes, but the tree is viewed as expanded. when i click the plus to
 expand/collapse a subtree (i click on that subtree for the 1st time), the
 plus changes to minus => the subtree was collapsed but was drawn as
 expanded - this happens with all the subtrees. is it a bug or am i doing
 something silly again?


    thank u for any help with this,
