Swing中使用Bean Binding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.javapackage 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.javapackage 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.javapackage 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.javapackage 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<Entity, String> inputtextProperty = BeanProperty
.create（"inputtext"）;
BeanProperty<JTextField, String> textProperty = BeanProperty
.create（"text"）; /* From java bean to swing component */
AutoBinding<Entity, String, JTextField, String>
binding1=Bindings.createAutoBinding（UpdateStrategy.READ_WRITE,
entity, inputtextProperty, textField, textProperty）; /* From swing component to java bean */
//AutoBinding<MyTextField, String, Entity, String> 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。Java Swing中的透明窗体（Windows中消息提示框的制作） http://www.linuxidc.com/Linux/2014-04/99622.htm用Java Swing编写简单的测试小工具界面（源码） http://www.linuxidc.com/Linux/2012-11/73566.htmJava 学习之 Swing 编程 http://www.linuxidc.com/Linux/2014-05/101049.htm本文永久更新链接地址：http://www.linuxidc.com/Linux/2014-11/109187.htm
