java 使用苹果主题风格 窗口透明酷炫效果

 

 

import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;

import com.sun.awt.AWTUtilities;

public class MainFrame extends JFrame {
private JButton button;
private JPanel panel;

public MainFrame() {
panel = new JPanel();
panel.setBounds(0, 0, this.getWidth(), this.getHeight());
panel.setBackground(Color.RED);
button = new JButton("Click Me！");
button.setBounds(50, 50, 100, 25);
this.setSize(800, 600);
this.setLocation(0, 0);
this.setLayout(null);
this.add(panel);
this.add(button);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);

button.addActionListener(new ActionListener() {

@Override
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null,
"My name is '牟孟孟', Nice to meet you!");

}
});
}

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
JFrame.setDefaultLookAndFeelDecorated(true);
UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");
} catch (Exception e) {
e.printStackTrace();
}
JFrame w = new MainFrame();
w.setBackground(Color.BLACK);
AWTUtilities.setWindowOpacity(w, 0.5f);
}
});

}
}

关键部分：
main方法里面：
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
JFrame.setDefaultLookAndFeelDecorated(true);
UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");
} catch (Exception e) {
e.printStackTrace();
}
JFrame w = new MainFrame();
w.setBackground(Color.BLACK);
AWTUtilities.setWindowOpacity(w, 0.5f);
}
});

}
注意：UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");
之前一定要加上JFrame.setDefaultLookAndFeelDecorated(true);
