Hi, is there someone who can help ?

I have a list with 5 items, only 2 must be visible, so I add my JList in a
JScrollPane to have a
vertical scrollingbar.

When I resize my frame, I resize also my list and the scrollpane by asking :
- my_jlist.setSize(new_width, new_height);
I ask to fix also the height and width of all my items :
my_jlist.setFixedCellHeight(new_height);
my_jlist.setFixedCellWidth(new_width);

- my_jscrollpane.setSize(new_width, new_height);

The problem is that by the resizing, the vertical scrollingbar disappears, I
can see all the items
in the list by scrolling with the arrows ( that let me perhaps know that the
scrollbar is no more yet visible), but what
do I miss ?
Something strange, is that when I give my frame its initial size, the
scrolling bar is visible !

I think I do not perform to resize my scrollpane, any ideas, solutions or
suggestions ?

Thanks a lot, :) Anne
