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

先来看看运行效果图：

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.JButton;import javax.swing.JComponent;import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.Painter;import javax.swing.SwingUtilities;import javax.swing.UIDefaults;import javax.swing.UIManager;import javax.swing.WindowConstants;public class ButtonSkinDemo { 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("Button")) { System.out.println(entry.getKey() + " = " + entry.getValue()); } } JFrame frame = new JFrame(" - Button 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 buttonDefaults = new UIDefaults(); buttonDefaults.put("Button.backgroundPainter", 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.fillRoundRect(0, 0, w - 2, h - 2, 8, 8); g.setColor(Color.LIGHT_GRAY); g.drawRoundRect(0, 0, w - 2, h - 2, 8, 8); } }); buttonDefaults.put("Button[Pressed].backgroundPainter", 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.LIGHT_GRAY); g.fillRoundRect(0, 0, w - 2, h - 2, 8, 8); } }); JButton button = new JButton("myButton"); panel.add(button); button.putClientProperty("Nimbus.Overrides", buttonDefaults); button.putClientProperty("Nimbus.Overrides.InheritDefaults", false); // Add a normal themed slider for comparison JButton normalButton = new JButton("normalButton"); panel.add(normalButton); frame.getContentPane().add(panel, BorderLayout.CENTER); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); }}
