摘要: 用过Flex的�h都知道有个基于MVC的puremvc框架�Q�这个框架因为小巧简单很受欢�q��?
PureMVC框架的目标很明确�Q�即把程序分��Z��耦合的三层：Model、View和Controller。降低模块间的耦合性，各模块如何结合在一起工作对于创建易扩展�Q�易�l�护的应用程序是非常重要的。在PureMVC实现的经典MVC元设计模式中�Q�这三部分由三个单例模式�cȝ��理，分别是Model、View和Controller。三者合�U�Cؓ核心层或核心角色。PureMVC中还有另外一个单例模式类—Facade�Q�Facade提供了与核心层通信的唯一接口�Q�以��化开发复杂度�?

Swing is Especially Effective If...

kissjava — Thu, 27 Nov 2008 03:57:00 GMT

You know your target domain or business logic, so that you are able to design expressive and concise domain objects.

You are thinking in "swing models", not the UI-components. If you understand your domain, you probably have an idea as well how to visualize the business concepts in object oriented way. The use of Swing models just becomes natural.

You are starting with the domain objects covered with unit tests, then develop the Swing models - after that the work is almost complete. You "only" have to create the view and pass the model to it.

You are NOT trying to work with the views directly and force them to behave in your way. This could become quite complex, cumbersome and very hard to maintain. E.g. if you are working with the JTable directly, instead of TableModel, even reordering the table columns can cause you some headaches. The are no issues with a custom model in this case.

The use of TableCellRenderers and TableCellEditors in JTables helps you to visualize you domain objects directly - without any overhead.

You are using visual designers like e.g. Matisse in pragmatic way and separate the generated, from your code.

You have a clear concept how to bind (e.g. with reflection+annotations or JSR-295) the UI-components to domain objects and how and where to validate the input (e.g. in controllers, domain objects or converters).

Try to leverage existing JavaBean patterns like PropertyChangeListener, PropertyChangeSupport and the already built-in listeners in the UI-components. There is lot of stuff which can be reused.

If you spend more than half hour to solve a specific "Swing-problem", just stop hacking and use google to find a solution for your problem. There are amazingly good tutorials, articles and posts out there.

If you lose your motivation. Just stop developing Swing, build a quick prototype with SWT/JFace for few hours (but use Tables and Trees). Your motivation should increase dramatically after this experiment :-)

JComboBox的下拉框向上

kissjava — Wed, 05 Mar 2008 03:21:00 GMT

csdn太慢啦，搬家��x��。。。�?br /> 最�q�学习SWING�Q�改变JComboBox的的昄��方式�Q�这里是��JComboBox的下拉框向上昄��Q�以下�ؓ详细代码�Q?

package kissJava.JComboBox;

import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.plaf.ComboBoxUI;
import javax.swing.plaf.ComponentUI;
import javax.swing.plaf.basic.BasicArrowButton;
import javax.swing.plaf.basic.BasicComboBoxUI;
import javax.swing.plaf.basic.BasicComboPopup;
import javax.swing.plaf.basic.ComboPopup;

public class PopupComboSample extends JFrame{
  String labels[] = { "Chardonnay", "Sauvignon", "Riesling", "Cabernet",
          "Zinfandel", "Merlot", "Pinot Noir", "Sauvignon Blanc",
          "Syrah", "Gewurztraminer" };
  JComboBox jcb = null;
public PopupComboSample(){
  this.setTitle("下拉框向�?/span>");
   this.setLayout(null);
    jcb = new JComboBox(labels);
    //setUI.......
    jcb.setUI((ComboBoxUI) MyComboBoxUI.createUI(jcb));
    jcb.setBounds(50, 150, 200, 20);
    this.add(jcb, null);
    setSize(300, 300);
    setVisible(true);
}

  public static void main(String args[]) {

     new PopupComboSample();

  }

  static class MyComboBoxUI extends BasicComboBoxUI {
   int newsBarTitleWidth = 0;

    public static ComponentUI createUI(JComponent c) {
      return new MyComboBoxUI();
    }
    //改变��头的方�?/span>
    protected JButton createArrowButton() {
      JButton button = new BasicArrowButton(BasicArrowButton.NORTH);
      return button;
    }
    //改变comboBox的弹出方�?/span>
    protected ComboPopup createPopup() {
     BasicComboPopup popup = new BasicComboPopup(comboBox){
      public void show() {
         //大小按需要更�?/span>
          Dimension popupSize = new Dimension(200 - newsBarTitleWidth - 5, 17 * 5);
          scroller.setMaximumSize(popupSize);
          scroller.setPreferredSize(popupSize);
          scroller.setMinimumSize(popupSize);
          show(comboBox, newsBarTitleWidth, -17 * 5);//getPopupHeightForRowCount(10));
    }
  };
  popup.getAccessibleContext().setAccessibleParent(comboBox);
  return popup;
}
  }
}

昄��效果为：

不过看图的效果jcb的输入框没有�U�条昄��Q�看来得再改改，学习中。。。。。。�?/p>
