发帖数: 493 | 2 Can you check the source code by yourslef? As I remember that even the data
model is null, the JList can be shown. (maybe I am wrong).
改变大小 will trigger the paintmanager to redraw the component. you can
always force to redraw compoenent in java swing. | h*****0

I didn't solve that problem coz when I add something else at the right of
the JList, the problem disappears.
I think I have to set the size of the JList(or outside JScrollPane), but i
don't know how to do it and not to interfere with the auto size according to
visible row count.
