VE设计#5 表现层delete界面

不想要这个联系人了怎么破？当然是删除啦。下面我们就来做删除界面。

还是同之前的方法，做一个如下如的deletePanel界面。因为我们是要删除，所以我们把传进来的元素设置为不可写的。

还是调用Myset（逻辑层）的delete方法。返回一个布尔值确定返回界面。返回按钮则是返回list界面。

实现代码如下：

/* * deleteJpanel.java * * Created on __DATE__, __TIME__ */package cn.hncu.ui;import javax.swing.Icon;import javax.swing.ImageIcon;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JOptionPane;import cn.hncu.busines.Myset;/** * * @author  __USER__ */public class deleteJpanel extends javax.swing.JPanel {private String deleteStr = null;private JFrame mainFrame = null;/** Creates new form deleteJpanel */public deleteJpanel(JFrame mainFrame, String deleteStr) {this.mainFrame = mainFrame;this.deleteStr = deleteStr;initComponents();myInit();setBack();}private void setBack() {this.setOpaque(false);Icon image=new ImageIcon("./image/delete.jpg");JLabel imageLbl=new JLabel(image);this.add(imageLbl);imageLbl.setBounds(0, 0, 800, 600);}private void myInit() {String strs[] = deleteStr.split(",");tfdName.setText(strs[0]);tfdAge.setText(strs[1]);tfdAddress.setText(strs[2]);tfdName.setEditable(false);tfdAge.setEditable(false);tfdAddress.setEditable(false);}/** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.
