gtk_clist_set_vadjustment()

[kai <tklam fieldtech com hk>]

Hi,

I am using GTK+1.2.10, I have some problem on "gtk_clist_set_vadjustment()".
Here is my code:

> >         if (GTK_IS_CLIST(l) && GTK_WIDGET_REALIZED(l) && g_list_length (GTK_CLIST(l)->selection) == 1){
> >                 GtkAdjustment *adj;
> >                 gint offset;
> >                 offset = GPOINTER_TO_INT(GTK_CLIST(l)->selection->data);
> >                 if ((GTK_CLIST(l) -> rows - offset)*GTK_CLIST(l) -> row_height <= GTK_CLIST(l) -> 
> > clist_window_height)
> >                         offset = GTK_CLIST(l) -> rows - (gint)(GTK_CLIST(l) -> clist_window_height/GTK_CLIST(l) 
> > -> row_height);
> >                 if ((adj = gtk_clist_get_vadjustment(GTK_CLIST(l)))!=NULL){
> >                         g_print("%f::%f::%f =>> %d\n", adj -> value, adj -> upper, adj -> lower, (offset * 
> > (GTK_CLIST(l) -> row_height + 1)));
> >                         gtk_adjustment_set_value(GTK_ADJUSTMENT(adj), (gfloat)( offset * (GTK_CLIST(l) -> 
> > row_height + 1)));
> >                         gtk_clist_set_vadjustment(GTK_CLIST(l), GTK_ADJUSTMENT(adj));
> >                 }
> >         }
I always can't set the expect adjustment.
Any simple example that illustrate the usage of 
"gtk_clist_set_vadjustment()"
Or any suggestion is also appreciate.
Thanks,

Kai
