GtkComboBox

[Pramod Patangay <pramod patangay gmail com>]

Hi,

I was trying out GtkComboBox. I have Gtk-2.4. I have created a
GtkTreeModel and populated the corresponding GtkTreeStore. But when I
run the program, the entries are not shown. Why is this happening? I
am attaching the program here:

GtkTreeStore *ts = gtk_tree_store_new(1,G_TYPE_STRING);
	GtkWidget *tv = gtk_tree_view_new_with_model(GTK_TREE_MODEL(ts));
	GtkCellRenderer* cr = gtk_cell_renderer_text_new();
	GtkTreeViewColumn* tvc =
gtk_tree_view_column_new_with_attributes(NULL, cr, "text", 0, NULL);
	gtk_tree_view_append_column (GTK_TREE_VIEW(tv), tvc);
	gtk_tree_view_set_headers_visible(GTK_TREE_VIEW(tv), FALSE);
	GtkTreeSelection* TS = gtk_tree_view_get_selection(GTK_TREE_VIEW(tv));
	gtk_tree_selection_set_mode(TS, GTK_SELECTION_BROWSE);

	GtkTreeIter iter;

	gtk_tree_store_insert(ts, &iter, NULL, 0);
	gtk_tree_store_set(ts, &iter, 0, "FIRST",-1);

	gtk_tree_store_insert(ts, &iter, NULL, 0);
	gtk_tree_store_set(ts, &iter, 0,"SECOND",-1);
	
	GtkWidget* combo = gtk_combo_box_new_with_model(GTK_TREE_MODEL(ts));
	gtk_container_add(GTK_CONTAINER(dialog),combo);
	gtk_widget_show(combo);

Can anyone please point out, why the entries are now show n in the combo box?

Thanks
