[QUESTION] a question about scrolled windows

[apple dragon <appledragon gmail com>]

a treeview(datasouce is liststore) in a scrolled window
and the treeview is sort automatic.

// gtk_container_add (GTK_CONTAINER (scrolledwindow), dirlist);

when I insert one item into the dirlist

	/* append the selected item into the list of the right */
	gtk_list_store_append(liststore,&iter);
	gtk_list_store_set(liststore,&iter,0,curselectedpath,-1);
	gtk_tree_selection_select_iter(listselection,&iter);

and make this item selected.

the question is when the item insert is NOT in the current page of
the scrolled window,how can I make the window auto scrolled and let
the item insert be in the current page. thanks a lot..
