本文实例讲述了java Swing组件定制RadioButton。分享给大家供大家参考，具体如下：

先来看看效果图：

具体代码如下：

package themedemo;

import java.awt.BasicStroke;

import java.awt.BorderLayout;

import java.awt.Color;

import java.awt.Graphics2D;

import java.awt.GridLayout;

import java.awt.RenderingHints;

import java.util.Map;

import javax.swing.BorderFactory;

import javax.swing.JComponent;

import javax.swing.JFrame;

import javax.swing.JPanel;

import javax.swing.JRadioButton;

import javax.swing.Painter;

import javORWnlAax.swing.SwingUtilities;

import javax.swing.UIDefaults;

import javax.swing.UIManager;

import javax.swing.WindowConstants;

public class RadioButtonSkinDemo {

public static void main(String[] args) {

SwingUtilities.invokeLater(new Runnable() {

public void run() {

for (UIManager.LookAndFeelInfo laf : UIManager

.getInstalledLookAndFeels()) {

if ("Nimbus".equals(laf.getName())) {

try {

UIManager.setLookAndFeel(laf.getClassName());

} catch (Exception e) {

e.printStackTrace();

}

}

}

for (Map.Entry

.getLookAndFeelDefaults().entrySet()) {

if ((entry.getKey().toString()).startsWith("RadioButton")) {

System.out.println(entry.getKey() + " = "

+ entry.getValue());

}

}

JFrame frame = new JFrame(

"jb51.net - RadioButton Skining Demo");

frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

frame.getContentPane().setLayout(new BorderLayout());

JPanel panel = new JPanel(new GridLayout(0, 1, 20, 20));

panel.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));

panel.setBackground(Color.darkGray);

UIDefaults radioButtonDefaults = new UIDefaults();

radioButtonDefaults.put("RadioButton.iconPainter",

new Painter() {

public void paint(Graphics2D g, JComponent c,

int w, int h) {

g.setRenderingHint(

RenderingHints.KEY_ANTIALIASING,

RenderingHints.VALUE_ANTIALIAS_ON);

g.setStroke(new BasicStroke(2f));

g.setColor(Color.WHITE);

g.fillOval(1, 1, w - 4, h - 4);

g.setColor(Color.LIGHT_GRAY);

g.drawOval(1, 1, w - 4, h - 4);

}

});

radioButtonDefaults.put("RadioButton[Selected].iconPainter",

new Painter() {

public void paint(Graphics2D g, JComponent c,

int w, int h) {

g.setRenderingHint(

RenderingHints.KEY_ANTIALIASING,

RenderingHints.VALUE_ANTIALIAS_ON);

g.setStroke(new BasicStroke(2f));

g.setColor(Color.WHITE);

g.fillOval(1, 1, w - 4, h - 4);

g.setColor(Color.DARK_GRAY);

g.fillOval(5, 5, w - 11, h - 11);

g.setColor(Color.LIGHT_GRAY);

g.drawOval(1, 1, w - 4, h - 4);

}

});

JRadioButton radioButton = new JRadioButton("myRadioButton");

panel.add(radioButton);

radioButton.putClientProperty("Nimbus.Overrides",

radioButtonDefaults);

radioButton.putClientProperty(

"Nimbus.Overrides.InheritDefaults", false);

// Add a normal themed slider for comparison

JRadioButton normalRadionButton = new JRadioButton(

"normalRadionButton");

panel.add(normalRadionButton);

frame.getContentPane().add(panel, Borhttp://derLayout.CENTER);

frame.pack();

frame.setLocationRelativeTo(null);

frame.setVisible(true);

}

});

}

}
