Hello,

I start develop aplication using lablgtk2, so in development
process some questions was raised.

1) I read tutorial about GtkTreeView

http://scentric.net/temp/tutorial/sec-custom-models.html#sec-custom-models-when

and I found very useful features in native gtk+-2.0:

    - create custom list and tree models;
    - create custom cell renderer;

Is it possible in lablgtk2 use this features?

In my mind tree_store interface not very handy for maintain big an
complicated data structue, so for any changes in my custom data I must do
parallel changes in tree_store.

2) In gtk exists function gtk-tree-model-foreach, and 
gtk_tree_model_iter_has_child.

It very useful for movement on tree_model. But I not found analog of these 
function
in lablgtk.

So what way of make analog foreach function for tree_store data rows?

3) It is possible save my custom data type in model store. For ex. I  need 
some like:

type my_custom_type = ......;

let cols = new GTree.column_list;;
let my_data_column = cols#add my_custom_type;;
