将 MVC/MVP 用于 Swing UI? [英] Using MVC/MVP for Swing UI?

问题描述

到现在为止，我已经使用了一些 java swing 代码，并将所有内容都放在一个类中.我想要设计和开发更好的 UI 应用程序.尝试将 MVP/MVC 用于 Swing UI，在任何地方都没有找到任何具体示例.

Till now I have worked with some java swing code with everything in one class. I want design and develop better UI application. Trying to use MVP/MVC for swing UI, didn't found any concrete example anywhere.

我想开发带有提交按钮的 Swing UI 表单.即这个代表用户表单的主面板包含三个面板:- 带有组合框和文本字段的标题面板.- 带有表格窗格的中心面板.- 带有一些组合框和文本字段的结束面板.

I want to develop swing UI form with submit button. i.e. this main panel representing user form contains three panels: - Header panel with combo box and text fields. - Center panel with table pane. - End panel with some combo box and text fields.

所以基本上我已经编写了 4 个没有动作监听器的 UI 类，一个用于主面板，三个用于标题、中心和结束面板.执行主面板显示所有组件.

So basically I have written 4 UI classes with no action listeners, one for main and three for header,center and end panel. Executing Main panel show me all the components.

我想向组合框提供运行时数据，当用户提交时，我应该从组合框和其他字段中获取选定的值.我应该如何使用 MVP/MVC 进行设计.任何人都可以提供一些解释或给我任何参考或示例的链接吗?

I want to provide runtime data to combo box and when user submit I should get selected values from combo box and other fields. How should I design using MVP/MVC. Could any one provide some explanation or give me a link to any reference or example?

推荐答案

看这个:Java - Learning MVC

MVC 模式需要这 3 个类.

The MVC pattern requires these 3 classes.

• theModel:处理数据
• theView:处理 GUI
• theController:处理监听器.

您可能需要先了解观察者模式.

You may need some understanding of the Observer pattern first.

设计可能如下:

public class Test {

    public Test(){
       MyModel      model      = new MyModel();
       MyController controller = new MyController(model);
    }
}

控制器类

public class MyController implements ActionListener {
    private MyView view;
    private MyModel model;

    MyController(MyModel theModel){
        model = theModel;
        view = new MyView(this);
        model.register(view);
    }

    // implement actionPerformed here
}

查看类

public class View implements Observer {
    private MyController controller;

    public View(){
         // Swing Components here
         JButton button = new JButton();
         button.addActionListener(controller);
         add(button);
    }
    // notifyObserver method implementation
}

模型类

public class MyModel extends Observable {
    // handle state/data changes here

}
