Nimbus L＆F - 改变进度条的背景颜色

Question

i'm developing a little GUI application with Java using Netbeans Editor. I've put in a JFrame a simple Progress Bar. I'm developing the project with JDK7

I want to change the background Color from default Orange to a personal one. I've already tried all the properties for the color changing but when i run the program the color still the same.

I've already tried using ProgressBar1.setBackground(new java.awt.Color(0, 204, 255));

and

UIManager.put("ProgressBar.background", Color.YELLOW);
UIManager.put("ProgressBar.foreground", Color.MAGENTA);
UIManager.put("ProgressBar.selectionBackground", Color.red);
UIManager.put("ProgressBar.selectionForeground", Color.green);

Same result..... The background is always orange

Here the code of my test project

public class Frame extends javax.swing.JFrame
{

    public Frame()
    {
        initComponents();
    }

    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">
    private void initComponents() {

        jProgressBar1 = new javax.swing.JProgressBar();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jProgressBar1.setBackground(new java.awt.Color(0, 204, 255));
        jProgressBar1.setValue(75);

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addContainerGap()
                .addComponent(jProgressBar1, javax.swing.GroupLayout.DEFAULT_SIZE, 380, Short.MAX_VALUE)
                .addContainerGap())
        );
        layout.setVerticalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addContainerGap()
                .addComponent(jProgressBar1, javax.swing.GroupLayout.PREFERRED_SIZE, 73, javax.swing.GroupLayout.PREFERRED_SIZE)
                .addContainerGap(javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
        );

        pack();
    }// </editor-fold>

    public static void main(String args[])
    {
        try
        {
            for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException ex) {
            java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (InstantiationException ex) {
            java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (IllegalAccessException ex) {
            java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (javax.swing.UnsupportedLookAndFeelException ex) {
            java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        //</editor-fold>

        /*
         * Create and display the form
         */
        java.awt.EventQueue.invokeLater(new Runnable() {

            public void run() {
                new Frame().setVisible(true);
            }
        });
    }
    // Variables declaration - do not modify
    private javax.swing.JProgressBar jProgressBar1;
    // End of variables declaration
}

and this is the result when you launch the code

Orange color....

EDIT With the following code

UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled].backgroundPainter", new FillPainter(Color.MAGENTA)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled].backgroundPainter", new FillPainter(Color.MAGENTA)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Indeterminate].progressPadding", new FillPainter(Color.ORANGE)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled].foregroundPainter", new FillPainter(Color.GREEN)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled].foregroundPainter", new FillPainter(Color.GREEN)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Finished].foregroundPainter", new FillPainter(Color.GREEN)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled+Finished].foregroundPainter", new FillPainter(Color.GREEN)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled+Indeterminate].foregroundPainter", new FillPainter(Color.GREEN)); 
UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Indeterminate].foregroundPainter", new FillPainter(Color.GREEN)); `

after this line

javax.swing.UIManager.setLookAndFeel(info.getClassName());

I've successfully change the color of background. But now the color is "plain", there is no gradient like the orange color.

Is it possible to change color with the same effect of the original color?

Answer 1

1. maybe ( Color and Font ) issue talking about Nimbus Look and Feel

2. have to check this thread

3. value for

ProgressBar[Disabled+Finished].foregroundPainter ProgressBar[Disabled+Indeterminate].foregroundPainter
ProgressBar[Disabled].backgroundPainter ProgressBar[Disabled].foregroundPainter ProgressBar[Enabled+Finished].foregroundPainter ProgressBar[Enabled+Indeterminate].foregroundPainter ProgressBar[Enabled+Indeterminate].progressPadding ProgressBar[Enabled].backgroundPainter ProgressBar[Enabled].foregroundPainter

. 4. maybe easiest for you will be to change nimbusOrange from the top of Nimbus default s, but this change is everywhere,

funny output to the GUI with changed Control Color , for example

UIManager.getLookAndFeelDefaults().put("nimbusOrange", (new Color(127, 255, 191)));

. 5. for example

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.EventQueue;
import java.awt.Graphics2D;
import javax.swing.*;

public class MyPopupWithNimbus {

    public MyPopupWithNimbus() {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(200, 200);
        JPanel panel = new JPanel(new BorderLayout());
        panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        JList list = new JList();
        panel.add(list);
        JProgressBar progress = new JProgressBar();
        progress.setStringPainted(true);
        progress.setString("60 pct");
        progress.setValue(60);
        frame.add(panel);
        frame.add(progress, BorderLayout.SOUTH);
        JPopupMenu menu = new JPopupMenu();
        menu.add(new JMenuItem("A"));
        menu.add(new JMenuItem("B"));
        menu.add(new JMenuItem("C"));
        JMenu jmenu = new JMenu("D");
        jmenu.add(new JMenuItem("E"));
        menu.add(jmenu);
        frame.setVisible(true);
        menu.show(frame, 50, 50);
    }

    public static void main(String[] args) {

        try {
            for (UIManager.LookAndFeelInfo laf : UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(laf.getName())) {
                    UIManager.setLookAndFeel(laf.getClassName());
                    UIManager.getLookAndFeelDefaults().put("nimbusOrange", (new Color(127, 255, 191)));
                    UIManager.getLookAndFeelDefaults().put("PopupMenu[Enabled].backgroundPainter",
                            new FillPainter(Color.ORANGE));
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                MyPopupWithNimbus aa = new MyPopupWithNimbus();
            }
        });
    }
}

class FillPainter implements Painter<JComponent> {

    private final Color color;

    FillPainter(Color c) {
        color = c;
    }

    @Override
    public void paint(Graphics2D g, JComponent object, int width, int height) {
        g.setColor(color);
        g.fillRect(0, 0, width - 1, height - 1);
    }
}

Answer 2

This is what I have done in the application I currently develop

ColorUIResource colorResource = new ColorUIResource(Color.red.darker().darker());
UIManager.put("nimbusOrange",colorResource);

This simply changes the default orange color with something more appealing to the eyes and it changes it everywhere.
