Details:

In Matlab an uicontrol listbox always tries to show the selected entry. If a
listbox is made and a value is selected like in the example, the bottom of the
visible listbox will show the selected entry


h = uicontrol('style','listbox','string','','units','normalized','position',[0
0 1 1]);
set( h, 'string', strread(num2str(1:100),'%s'), 'value', 50 )


If an earlier selection is made, the visible area of the listbox will move to
show the top entry selected

set( h, 'value', 5 )


It seems it is not programatically possible yet to move the listbox visible
area.
