Java实现Swing组件定制Button示例

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("www.VeVB.COm - 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);   }  }); }}
