Swing中使用BeanBinding实例

最近在做一个java swing的小程序，试了一下Bean Binding，需要用到的lib有两个，appframework-1.03.jar和beanbind-1.2.1.jar. 完整代码如下：

Entrance.java

package main;

import swing.MainFrame;

public class Entrance {
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		MainFrame mf = new MainFrame();
		mf.setup();
	}
}

Entity.java

package bean;

import java.beans.PropertyChangeListener;
import java.beans.PropertyChangeSupport;

public class Entity {
	private String inputtext;

	private PropertyChangeSupport changeSupport=new PropertyChangeSupport(this);
	public String getInputtext() {
		return inputtext;
	}

	public void setInputtext(String inputtext) {
		String oldText=this.inputtext;
		this.inputtext = inputtext;
		changeSupport.firePropertyChange("inputtext", oldText, inputtext);
		
	}

	public void addPropertyChangeListener(PropertyChangeListener listener){
		changeSupport.addPropertyChangeListener(listener);
	}
	
	public void removePropertyChangeListener(PropertyChangeListener listener){
		changeSupport.removePropertyChangeListener(listener);
	}
}

MainFrame.java

package swing; 

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JFrame;


public class MainFrame {
       private JFrame frame;
       public void setup(){
    	   frame=new JFrame();
           frame.setPreferredSize(new Dimension(600,400));
           frame.getContentPane().add(new MainWindow().createPanel(),BorderLayout.CENTER);
           frame.setVisible(true);
           frame.addWindowListener(new windowEventHandler());
       }
       class windowEventHandler extends WindowAdapter{
     	   public void windowClosing(WindowEvent e){
     		   System.out.println("Exit");		
    			   System.exit(0);
     	   }
        }
}
 

MainWindow.java

package swing;

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JTextField;

import org.jdesktop.beansbinding.AutoBinding;
import org.jdesktop.beansbinding.BeanProperty;
import org.jdesktop.beansbinding.Bindings;
import org.jdesktop.beansbinding.AutoBinding.UpdateStrategy;

import bean.Entity;

public class MainWindow implements ActionListener {
	private JPanel mainPanel;
	private JTextField textField;
	private JButton button;
	public final static Entity entity = new Entity();

	public JPanel createPanel() {
		mainPanel = new JPanel();
		mainPanel.setLayout(new BorderLayout());
		mainPanel.setPreferredSize(new Dimension(300, 200));
		textField = new JTextField();

		BeanProperty inputtextProperty = BeanProperty
				.create("inputtext");
		BeanProperty textProperty = BeanProperty
				.create("text");

		/* From java bean to swing component */
		 AutoBinding
		 binding1=Bindings.createAutoBinding(UpdateStrategy.READ_WRITE,
		 entity, inputtextProperty, textField, textProperty);

		/* From swing component to java bean */
		//AutoBinding binding2 = Bindings
		//		.createAutoBinding(UpdateStrategy.READ_WRITE, textField,
		//				textProperty, entity, inputtextProperty);
		binding1.bind();
		//binding2.bind();
		mainPanel.add(textField, BorderLayout.CENTER);
		button = new JButton("Change Text");
		button.addActionListener(this);

		mainPanel.add(button, BorderLayout.SOUTH);
		return mainPanel;
	}

	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
		if (e.getSource() == button) {
			/* From java bean to swing component */
			 entity.setInputtext("Hello");
			 System.out.println("entity value: "+entity.getInputtext());
			 System.out.println("component value: "+textField.getText());
			 mainPanel.updateUI();

			/* From swing component to java bean */
			//System.out.println("component value: " + textField.getText());
			//System.out.println("entity value: " + entity.getInputtext());
		}
	}
}

说明：

上述代码只实现了修改java bean中attribute中的值能够自动在swing component中通过beanbinding显示出来，反过来并不成立，如果有大虾知道如何通过修改component的属性值从而自动修改bean中的属性值，还请指教。
