JTable的问题

[panq]

想用两个JTable，都是列是一位的，中间有一个button，左边的JTable内已经有数据，且不能更改，右边的JTable各行为空，选中左边JTable中的一个record,点击中间的button,能够在右边JTable中出现该record。
各位大虾，这该如何做，给出思路和代码都好。

首先实现TableModelListener(其实什么事也不用做,但是只有这样 JTable的数据显示才会更新)
class UserTableModelListener implements TableModelListener {

public UserTableModelListener() {
}

public void tableChanged(TableModelEvent e) {
}
}

然后继承DefaultTableModel,让JTable不能编辑.
class UserTableModel extends DefaultTableModel {
public CustomTableModel(Object[][] data, Object[] colname) {
super(data, colname);
}

public boolean isCellEditable(int x, int y) {
return false;
}

public void addTableModelListener(UserTableModelListener l) {
super.addTableModelListener(l);
}


}

这是你的frame
public class YourApp extends JFrame
{
JTable ltable = null;
JTable rtable = null;
UserTableModel lmodel = null;
UserTableModel rmodel = null;

public YourApp() {
try {
yourInit();
}
catch(Exception e) {
e.printStackTrace();
}
}

private void yourInit() throws Exception {
Object[][] yourdata = yourdata;
Object[][] zerodata = new Object[0][0];
Object[] yourcolname = yourcolname;
lmodel = new UserTableModel(yourdata, yourcolname);
rmodel = new UserTableModel(zerodata, yourcolname);
ltable = new JTable(lmodel);
rtable = new JTable(rmmodel);

lmodel.addTableModelListener(new UserTableModelListener());
rmodel.addTableModelListener(new UserTableModelListener());

JButton add = new JButton("add");
add.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
actionPerformed(e);
}
});
}

void actionPerformed(ActionEvent e) {
int row = ltable.getSelectedRow();
String[] data = new String[1];
data[0] = (String)ltable.getValueAt(row, 0);
lmodel.removeRow(row);
rmodel.addRow(data);
}
}

实在抱歉,编译花了不少时间,实在是我蠢,怎么也不成功.请问DefaultTableModel是什么,我查javaAPI,查不到.

以下是出错的地点和内容:
class UserTableModel extends DefaultTableModel {

"YourApp.java": Error #: 300 : class DefaultTableModel not found in class dbdump.UserTableModel at line 26, column 32

代码没有办法写了。说说思路好了。
左边的jtable,当你选中的时候，你能得到所有被选中的行(所以可以几行一起到右边的jtable),
来个循环,取的所有的行号及值(不要怀疑，我都做过),同时右边的jtable插入行，行的值就是你从左边取出来的值。
呵呵，以你的功底一定很容易的。

[lovesnoopy]

我已经写得这么详细了(除了界面布局的代码),你还想要什么思路,代码?

[rinehart]

DefaultTableModel是java 的 api!

这一段有点问题：
然后继承DefaultTableModel,让JTable不能编辑.
class UserTableModel extends DefaultTableModel {
~~~~~~~~~~~~~~
public CustomTableModel(Object[][] data, Object[] colname) {
~~~~~~~~~~~~~~~~
super(data, colname);
}

public boolean isCellEditable(int x, int y) {
return false;
}

public void addTableModelListener(UserTableModelListener l) {
super.addTableModelListener(l);
}

}

类名和构造函数名不一样，是不是这个问题！？

支持一把

[lovesnoopy]

sorry,原来的class叫CustomTableModel,copy后只改名，构造函数忘了改了。不好意思。
to panq: import javax.swing.table.DefaultTableModel；

一切OK, 感谢lovesnoopy(洋葱头)　和rinehart(rinehart)　还有cming(白云蓝天)
也感谢一切gz的朋友,一概有分.
　
以下是我的调试程序.

import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;

class UserTableModelListener implements TableModelListener {

public UserTableModelListener() {
}

//然后继承DefaultTableModel,让JTable不能编辑.
class UserTableModel extends DefaultTableModel {

super(data, colname);
}

public boolean isCellEditable(int x, int y) {
return false;
}

public void addTableModelListener(UserTableModelListener l) {
super.addTableModelListener(l);
}


}

//这是你的frame
