I have a GUI consisting of a JList and JButton. The JList displays text items in black. When an item is selected the background color changes to red. I want to have the color of the selected text change to white when the user clicks on the JButton. In other words, the text color for the (already) selected item should change without requiring the user to click on the text item again. Can you show me how to accomplish this?
Thank you.

create a boolean flag (field)

button's actionListener: change flag to true and repaint

listSelectionListener: change flag to false

listRenderer: set foreground
if(isSelected && flag) white
else black

Is JList.setSelectionBackground() not working for you?
 
Don't get me started about those stupid light bulbs.
