GtkCList gtk_clist_move_to

[g zandini ml org]

hi, 
I am rather new to this gtk stuff, so please correct me if
I am way off the track.

I was created a gtk_clist and then I tried to connect two buttons 
to scroll up and down the list. but some how gtk_clist_move doesn't
do anything. Or is gtk_clist_move used for something else?
here is the code I wrote.


void scroll_down ( GtkWidget * widget, gpointer data ) {
    gtk_clist_moveto ( GTK_CLIST(data), pos_row+= 10, pos_col, 0.0,0.0 );
}

void scroll_up ( GtkWidget * widget, gpointer data ) {
    gtk_clist_moveto ( GTK_CLIST(data), --pos_row, pos_col, 0.0, 0.0);
}

... and in another function 

    panel = gtk_clist_new( 2 );

    gtk_clist_set_column_title ( GTK_CLIST (panel), 0, "line");
    gtk_clist_set_column_title ( GTK_CLIST (panel), 1, filename);
    gtk_clist_column_titles_show ( GTK_CLIST (panel));

    button = new_button_with_pix ( table, "up.xpm", "UP" );
    gtk_signal_connect ( GTK_OBJECT(button), "clicked",
            GTK_SIGNAL_FUNC ( scroll_up ), (gpointer) panel );
    gtk_widget_show ( button);
    button = new_button_with_pix ( table, "down.xpm", "DOWN" );
    gtk_signal_connect ( GTK_OBJECT(button), "clicked",
            GTK_SIGNAL_FUNC ( scroll_down ), (gpointer) panel );
    gtk_widget_show ( button);



I'll appreciate any help, comments.
Thanx =)
