[Java-gnome-developer] problems with treeview

[Alex M. <ale...@gl...>]

Hi,

i´m working on porting a password manager written in swing to
java-gnome and, at the same time, i´m writing a glade tutorial with
those things wich i´m learning.

Now i´m working on treeview and i´ve got a little problem. When
i get the libglade widget i try to add new nodes to the tree, but
treeview doesn´t respond. I´m doing something like this:

//************** CODE *******************//

            main = (Window) libglade.getWidget("main");
            tree = (TreeView) libglade.getWidget("treeview");

			// Make some data blocks to refer to the data for the tree
			DataBlockString dataString = new DataBlockString();
			DataBlockInt dataInt = new DataBlockInt();
			DataBlockBoolean dataBool = new DataBlockBoolean();
			DataBlockPixbuf dataPix = new DataBlockPixbuf();
[....]

			// create a new column to be visible in the output, set a title for it and
			// append it to the tree.
			TreeViewColumn column1 = new TreeViewColumn();
			column1.setTitle("Main Data");
			tree.appendColumn( column1 );

			tree.show();
			main.showAll();		

//************** CODE *******************//

That last lines should to include the new column to the tree, as shown in
java-gnome examples... but as i said, it doesn´t happens anything. 

Doing something like 
		tree = new TreeView(store);
didn´t help.

In swing i often modified trees getting the tree model and working on it:

				DefaultTreeModel model;
				model = (DefaultTreeModel)controlador.cvp.win.jt.getModel();

				//insercion del nuevo nodo en el jtree
				model.insertNodeInto(nuevoNodo,chosen, 0);

but this doesn´t seems to work on java-gnome.


Can anyone help me or send me a treeview java-gnome example designed in
glade? Thanks a lot.
