GtkTreeView questions

[Yves Kurz <shorty kurz-technik ch>]

Hello..  
I'm trying to write a small gtk application which is using the
GtkTreeView widget. Now i have some questions and i hope someone can
give me a little help.

1. How is it working with freeing the resources of a widget?
I'm doing this:

store = >store = gtk_list_store_new (n_cols, G_TYPE_BOOLEAN);
view = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store));

is a simple gtk_widget_destroy (GTK_WIDGET (view)) enough to free the
store (with all it's content) and the view?


2. I would like to use the EGG_TREE_FILTER but i don't know how to do it
right. I get all the time just an empty list.

store = >store = gtk_list_store_new (n_cols, G_TYPE_BOOLEAN);
filter = egg_tree_model_filter_new (GTK_TREE_MODEL (gs->store),
gtk_tree_path_new_first ());

egg_tree_model_filter_set_visible_column (EGG_TREE_MODEL_FILTER
(filter), 1);
or 
egg_tree_model_filter_set_visible_func (EGG_TREE_MODEL_FILTER (filter),
filter_visible_all, NULL, NULL);

view = gtk_tree_view_new_with_model (GTK_TREE_MODEL (filter));

What ist wronge here?? 


Thank you.. 

yves
