Java Swing - JList custom cell rendering - capturing actions

Question

Any time I make a custom cell renderer for a JList, any elements I add to it don't ever respond to actions. For instance, If I have the cell renderer return a JPanel with elements on it, one of which has an ActionListener, it doesn't respond at all.

Why is this?

Answer 1

The item you return as a list cell renderer is intended for exactly that: rendering. Register listeners with the JList (generally, you'll want a ListSelectionListener).
