设计模式第三周作业「架构师训练营第 1 期」

public abstract class Element {
    protected String id;
    protected String value;
    //渲染
    public abstract  void draw();
}
public class WinForm extends Element{
    List<Element> subNodes = new ArrayList<>();
    public WinForm(String value) {
        this.value = value;
    }
    public WinForm(){
    }
    public void addSub(Element element){
        subNodes.add(element);
    }
    @Override
    public void draw() {
        System.out.println("print winForm "+value);
        for (Element subNode : subNodes) {
            subNode.draw();
        }
    }
}
public class Frame extends Element{
    List<Element> subNodes = new ArrayList<>();
    public Frame(String value) {
        this.value = value;
    }
    public Frame(){
    }
    public void addSub(Element element){
        subNodes.add(element);
    }
    @Override
    public void draw() {
        System.out.println("print frame "+value);
        for (Element subNode : subNodes) {
            subNode.draw();
        }
    }
}
public class Button extends Element{
    public Button(String value) {
        this.value = value;
    }
    public Button(){
    }
    @Override
    public void draw() {
        System.out.println("print button "+value);
    }
}
其它label textbox等组件同button
public class Client {
    public static void main(String[] args) {
        WinForm winForm = new WinForm("window窗口");
        Picture picture = new Picture("logo图片");
        Button loginbtn = new Button("登录");
        Button regbtn = new Button("注册");
        Frame frame = new Frame("frame1");
        Label label = new Label("用户名");
        TextBox textBox = new TextBox("文本框");
        Label pwdlabel = new Label("密码");
        PasswordBox passwordBox = new PasswordBox("密码框");
        CheckBox checkBox = new CheckBox("复选框");
        Label remeberlabel = new Label("记住用户名");
        LinkLabel linkLabel = new LinkLabel("忘记密码");
        winForm.addSub(picture);
        winForm.addSub(loginbtn);
        winForm.addSub(regbtn);
        winForm.addSub(frame);
        frame.addSub(label);
        frame.addSub(textBox);
        frame.addSub(pwdlabel);
        frame.addSub(passwordBox);
        frame.addSub(checkBox);
        frame.addSub(remeberlabel);
        frame.addSub(linkLabel);
        winForm.draw();
    }
}
