hi santhosh;

          thanks for the reply, i am getting the warning like

GLib-GObject-WARNING **: invalid (NULL) pointer instance
 
GLib-GObject-CRITICAL **: g_signal_emit_by_name: assertion
`G_TYPE_CHECK_INSTANCE (instance)' failed

           the code i have in "on_text_entry_activate" call back is 

void
on_text_entry_activate         (GtkEntry        *entry,
                                gpointer         user_data)
{
        GtkWidget *sst_file_sel;
        
        sst_file_sel = create_window_ssnew2 ();
        
        const gchar *s = gtk_entry_get_text(GTK_ENTRY (entry));
                

        if (strlen(s)>0) 
        
        {
        printf ("Entry contents: %s \n", s);
        gtk_entry_set_text(GTK_ENTRY (entry),"");
        }

}

and in "on_button_next_clicked" callback i just added the one u given.

void
on_button_next_clicked     (GtkButton       *button,
                            gpointer         user_data)
{
        g_signal_emit_by_name (entry, "activate", NULL); 
     
}

what else i have to add to get my functionality;

thanks;

vasu.
