Re: Forcing a JList to refresh one cell

I have a JList where each item in the list is rendered by a

repaint on the whole JList, I can't seem to make it repaint the cell that
changed.

Look in
javax.swing.AbstractListModel
and its method
protected void fireContentsChanged(Object, int, int)

Practically you'll need to create your own model extends AbstractListModel if you don't have one.
