Swing最新特性：增加透明窗体及不规则窗体功能
最新的jdk-6u10版本已经在进行beta测试，对于swing来说，在此版本中增加了两个重要的功能：透明窗体和
不规则窗体。这两个功能使得swing也可以做出vista下的玻璃效果来了，
jdk-6u10可以在http://download.java.net/jdk6/binaries/进行下载
透明窗体：
public class TranslucentWindow extends JFrame {
public TranslucentWindow() {
super("透明窗体");
this.setLayout(new FlowLayout());
this.add(new JButton("按钮"));
this.add(new JCheckBox("复选按钮"));
this.add(new JRadioButton("单选按钮"));
this.add(new JProgressBar(20, 100));
this.setSize(new Dimension(400, 300));
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
JFrame.setDefaultLookAndFeelDecorated(true);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
Window w = new TranslucentWindow();
w.setVisible(true);
com.sun.awt.AWTUtilities.setWindowOpacity(w, 0.6f);
}
});
}
}
不规则窗体：
public class ShapedWindow extends JFrame {
public ShapedWindow() {
super("不规则窗体");
this.setLayout(new FlowLayout());
this.add(new JButton("按钮"));
this.add(new JCheckBox("复选按钮"));
this.add(new JRadioButton("单选按钮"));
this.add(new JProgressBar(0, 100));
this.setSize(new Dimension(400, 400));
this.setLocationRelativeTo(null);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
JFrame.setDefaultLookAndFeelDecorated(true);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
Window w = new ShapedWindow();
w.setVisible(true);
com.sun.awt.AWTUtilities.setWindowShape(w, new Ellipse2D.Double(0, 0, w.getWidth(), com.sun.awt.AWTUtilities.setWindowOpacity(w, 0.93f);
}
});
}
}
