Matisse Form使用：
一：new 界面
1)new – Matisse Form（如果没有，用2)）
2)new–Other–MyElipese–Swing– Matisse Form
二：必须有一个内容窗格（Application），往内容窗格内加面板（JPanel)
三：对面板格式的设置
1)点右键，会有设布局，一般选null空布局，在Add Form Palate–SwingControls会有添加各种组件，选中某一组件点右键可对组件进行（重命名，设文本，大小，添加监听等）操作
2)在Windows菜单中-show view–Matisse Palate–SwingControls可添加各种Swing组件
show view–Properties选中组件或者界面，在Properties中即可对其进行设置
四：组件可以被复制。注:原来的组件在上面，复制之后的组件在下面，使用组件的时候要把组件换一下

这里写图片描述

在内容窗格上添加listPanel（第一次运行），之后根据功能需要显示不同的面板，所以要把内容窗格this传给listPanel，并且每次换功能面板都要拿this

package cn.hncu.addr;

import cn.hncu.addr.ui.listPanel;

public class AddressApp extends javax.swing.JFrame {
   
   

    /** Creates new form AddressApp */
    public AddressApp() {
        this.setContentPane(new listPanel(this));//把this传给listPanel
        this.validate();//相当于刷新界面
        initComponents();//WARNING: Do NOT modify this code.The content of this method is always regenerated by the Form Editor.这里的代码不能修改，因为他每次都会根据Form Editor重新生成
    }
    /** This method is called from within the constructor to
     * initialize the form.
     * ***WARNING:*** Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
