UIManager color at a JFileChooser

Solution 1:

JFileChooser is compound JComponent, you can extract JButtons, JToggleButtons and JScrollPane with JViewPort that contains JList, please download Darryl's Swing Utils , read descriptions, then run (Darryl's) code, result is selection for JList or JTable (I voting for that)

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.*;
import javax.swing.plaf.metal.MetalButtonUI;

public class CrazyFileChooser {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new CrazyFileChooser().makeUI();
            }
        });
    }

    public void makeUI() {
        JFileChooser chooser = new JFileChooser();
        for (AbstractButton button : SwingUtils.getDescendantsOfType(AbstractButton.class, chooser)) {
            button.setUI(new XORButtonUI());
        }
        for (JList list : SwingUtils.getDescendantsOfType(JList.class, chooser)) {
            list.setBackground(Color.PINK);
        }
        chooser.showOpenDialog(null);
    }
}

class XORButtonUI extends MetalButtonUI {

    @Override
    public void paint(Graphics g, JComponent c) {
        g.setXORMode(Color.YELLOW);
        super.paint(g, c);
    }
} 

Solution 2:

Well, there is one way possible to do it. You can get the JList from your JFileChooser and modify it:

public boolean getJList(Container c)
{
    Component[] cmps = c.getComponents();
    for (Component cmp : cmps)
    {
        if (cmp instanceof JList)
        {
            modifyJList((JList)cmp);
            return true;
        }
        if (cmp instanceof Container)
        {
            if(getJList((Container) cmp)) return true;
        }
    }
    return false;
}
private void modifyJList(JList list)
{
    // Here you can modify your JList
}

and to use it, just call getJList():

JFileChooser chooser = new JFileChooser();
getJList(chooser);

Solution 3:

I really don't know, but have you tried setting this properties:

List.selectionForceground
List.selectionBackground

A FileChooser looks pretty much like a list...

Second try. Maybe settings these helps:

controlHighlight
controlLHighlight
