UIManager color at a JFileChooser

问题

I\'m using Nimbus Look and Feel, with only 3 changes at its colors:

UIManager.put(\"nimbusSelection\", new Color(164,164,164));
UIManager.put(\"nimbusSelectionBackground\", new Color(214,217,223));
UIManager.put(\"nimbusSelectedText\", Color.BLACK);

My FileChooser looks like this:

$\"enter$

So selected file\'s name appears in white and looks bad, and it also happens for the file type selected at the combobox. I want to change it to Black, but nimbusSelectedText is already black and is not working.

I also had a look at the Nimbus Defaults guide at http://download.oracle.com/javase/tutorial/uiswing/lookandfeel/_nimbusDefaults.html#primary and i see no parameter at FileChooser or Combobox to fix this.

Any help identifying the necessary parameters? Thanks

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);

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);
    }
}

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
