GtkWidget *create_interface(void)
    532 {
    533         static Hybrid *hybrid = NULL;
    534 
    535         GtkWidget *w, *main_box, *progress, *m_frame, *menu_table,
		*button, *opt, *menu, *quitbox, *label, *separator;
    536         
		GtkWidget *scrolled_window, *vbox, *table;
    537 
    538         hybrid = g_malloc( sizeof(Hybrid) );
    539         g_assert (hybrid != 0);

		/* some where I do this */
		hybrid->scrolled_window = create_scrolled_window();

GtkWidget *create_scrolled_window (void)
    513 {
    514 
    515                 GtkWidget *scrolled_window;
    516 
    517                 scrolled_window = gtk_scrolled_window_new (NULL,
								   NULL);
    518                 gtk_container_set_border_width (GTK_CONTAINER
						       (scrolled_window),
						       _TEN);
    519                 gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW
						      (scrolled_window),
						      GTK_POLICY_AUTOMATIC,
						    GTK_POLICY_AUTOMATIC);
    522                 gtk_widget_set_usize( GTK_WIDGET
					      (scrolled_window), XSIZE,
					      _FOURH);
    523 
    524 
    525                 return scrolled_window;
}
Then after time out, and the call to data base I do this:
 update_scrolled_window(hybrid);

gint update_scrolled_window (Hybrid *hybrid)
    103 {
    104                 GtkWidget *table;
    105 
    106                 if (hybrid->table == NULL)
    107                 {
    108                         create_table(hybrid);
    109 
    110                         /*gtk_widget_show(hybrid->table);*/
    111                         gtk_scrolled_window_add_with_viewport
						(GTK_SCROLLED_WINDOW (hybrid->scrolled_window), hybrid->table);
    112                         gtk_container_set_focus_hadjustment
						(GTK_CONTAINER (hybrid->table),
    113
				gtk_scrolled_window_get_hadjustment (GTK_SCROLLED_WINDOW
						(hybrid->scrolled_window)));
    114 
    115                         gtk_container_set_focus_vadjustment
						(GTK_CONTAINER (hybrid->table),
    116
				gtk_scrolled_window_get_vadjustment (GTK_SCROLLED_WINDOW
						(hybrid->scrolled_window)));
    117                 }
    118                 return FALSE;
    119 }

And here I build the table refered to on line# 108 above

gint create_table (Hybrid *hybrid)
     38 {
     39 
     40         GtkWidget *vrule, *lh, *lable, *table;
     41         int col, row;
     42 
     43         ServerData *current = NULL;
     44 
     45         current = g_malloc( sizeof(ServerData) );
     46         current = hybrid->sd;
     47 
     48         table = gtk_table_new(_TWO, hybrid->count, TRUE);
     49        
     50         vrule = gtk_vruler_new();
     51         gtk_ruler_set_metric( GTK_RULER(vrule), GTK_PIXELS );
     52         gtk_ruler_set_range( GTK_RULER(vrule),
				     ceil(hybrid->max_load) + _FIVE, _NON,
				     hybrid->max_load, _TWOH );
     53         gtk_table_attach_defaults( GTK_TABLE(table),
     54                                    vrule,
     55                                    _NON,
     56                                    _ONE,
     57                                    _NON,
     58                                    _ONE);
     59 
     60 
     61         gtk_table_set_col_spacings( GTK_TABLE (table),
     62                                     _FIVE);
     63 
     64         col = row = 1;
     65 
     66         while ( current != NULL )
     67         {
     68                 lh = gtk_level_hold_new( _TWOH,
     69                                          _TEN,
     70                                          GTK_LEVEL_HOLD_FADE,
     71                                          _EIGHT,
     72                                          _THREE,
     73                                          _TWO);
     74 
     75                 gtk_table_attach_defaults( GTK_TABLE(table),
     76                                            lh,
     77                                            col,
     78                                            col + _ONE,
     79                                            _NON,
     80                                            _ONE);
     81 
			lable = gtk_label_new (current->name);
     85                 gtk_table_attach_defaults( GTK_TABLE(table),
     86                                            lable,
     87                                            row,
     88                                            row + _ONE,
     89                                            _ONE,
     90                                            _TWO);
     91                  gtk_timeout_add(1000, update_bars,lh);
     92                  col++;
     93                  row++;
     94                  current = current->nextptr;
     95         }
     96         g_free(current);
     97         hybrid->table = table;
     98 
     99         return FALSE;
}
I am sorry for this thing being so big and nasty, but I thought if you saw
it, may be you may have a clue...
Thanks in advance
