I'd do (after having done the above):
g_list *node);
for(node=my_list; node; node=node->next) {
GtkTreeIter iter;
if(gtk_tree_model_get_iter(model, &iter, node->data)) {
/* now iter is a valid row iterator */
GValue val;
gint col;
for(col=0; col<gtk_tree_model_get_n_columns; col++) {
/* assume column 0 is a gchar* and column 1 is a gint.
See gtk_tree_model_get_value() and _type() for when you
don't know how the model is built */
gchar *name; /* col 0 */
gint age; /* col 1 */
gtk_tree_model_get(model, &iter,
0, &name,
1, &age,
-1 /* end */);
g_message("%s is %d years old", name, age);
g_free(name);
}
}
gtk_tree_path_free(node->data); /* if you don't need it anymore */
}
g_list_free(my_list);
See
<http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeModel.html#gtk-tree-model-get-iter>
for an explanation of how all this works. There is a slightly simpler
way if you just want to iterate throught the selection without modifying
the model:
selection = gtk_tree_view_get_selection(list_file_treeview);
model = gtk_tree_view_get_model(list_file_treeview);
gtk_tree_selection_selected_foreach(selection, selfun, NULL);
and then:
void selfun(GtkTreeModel *mo, GtkTreePath *path, GtkTreeIter *it, gpointer
data)
{
gchar *name; /* col 0 */
gint age; /* col 1 */
gtk_tree_model_get(model, &iter,
0, &name,
1, &age,
-1 /* end */);
g_message("%s is %d years old", name, age);
g_free(name);
}
