JList selected data from highlighted

Question

What I am trying to do with a JList is be able to select an index by either scrolling with the mouse or using the keyboard up or down buttons without requiring a key press or mouse click event. I have tried looking into listeners and I think that's the right direction to go but if someone could put it simply I would appreciate it so much.

//edit.

To add more detail here is an example of what i mean, see Halo 3 is high lighted but the stock item name etc is for halo 4

Answer 1

You need to add a ListSelectionListener to the ListModel of the JList . Then when the selection event is generated you invoke your logic to update the two text fields.

Read the section from the Swing tutorial on How to Write a List Selection Listener for more information and examples.
