hi;

       i creeated with glade like, window with button_simp_list_get_ent,
and treeview_ent_widget, when i press button_simp_list_get_ent, another
window with entry_simp_list_entry, and button_simp_entry, will pop up.
now when i enter data and press button_simp_entry, the entered text has
to append to the treeview_ent_widget(created with glade). window
displaying but i can't able to append data. i am not getting any error.

here is the developed one:

enum
{
  COL_TEXT = 0,
  NUM_COLS
};

void
on_button_simp_list_get_ent_pressed    (GtkButton       *button,
                                        gpointer         user_data)
{
   gtk_widget_show (create_window_simp_entry());/*-->displays window
with entry, button*/
        
}


void
on_entry_simp_list_entry_activate      (GtkEntry        *entry,
                                        gpointer         user_data)
{
        
GtkWidget *win_simp_entry, *win_simp_list, *win_simp_list1, *button;
        
        win_simp_list1 = create_window_simp_list ();
