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 javax.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<Object, Object> entry : UIManager .getLookAndFeelDefaults().entrySet()) { if ((entry.getKey().toString()).startsWith("RadioButton")) { System.out.println(entry.getKey() + " = " + entry.getValue()); } } JFrame frame = new JFrame( "www.VeVB.COm - 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<JComponent>() { 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<JComponent>() { 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, BorderLayout.CENTER); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); }}更多关于java算法相关内容感兴趣的读者可查看本站专题：《Java数据结构与算法教程》、《Java操作DOM节点技巧总结》、《Java文件与目录操作技巧汇总》和《Java缓存操作技巧汇总》
