仍然是这里的 Java 新手，试图为我自己的利益提供太先进的东西。不过，这就是我需要做的：JXTreeTable 中的一个复选框。我的主要课程：

public class TestFrame extends JFrame {
/**

TestFrame frame = new TestFrame();
frame.setVisible(true);

e.printStackTrace();

}
/**

*/
public TestFrame() {
setMinimumSize(new Dimension(600, 600));
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 546, 600);
JPanel contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(new MigLayout("", "[grow][grow][grow][100px:n,grow][grow][grow][grow]", "[][251.00,grow][]"));
List<Job> jobList = new ArrayList<Job>();

itemList.add(new ItemDetail("N10", "N10", 2, 1000, PrintType.PAD, true));

// create and add the first job with its list of ItemDetail objects

// we use a no root model

treeTable = new JXTreeTable(noRootTreeTableModel);
treeTable.setEditable(false);
treeTable.setRootVisible(false);
treeTable.setBorder(new EtchedBorder(EtchedBorder.LOWERED, null, null));
treeTable.getTableHeader().setReorderingAllowed(false);
treeTable.getColumn(0).setPreferredWidth(200);

JScrollPane scrollPane = new JScrollPane(treeTable);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);

}
}
Job 类（TreeTable 中的分支）：
package info.chrismcgee.sky.production;
import java.awt.Checkbox;
import java.util.List;
import org.joda.time.LocalDate;
public class Job {
private Checkbox cbJob;
private String idNumber;
private LocalDate shipDate;
private List<ItemDetail> itemList;
public Job(Checkbox cbJob, String idNumber, LocalDate shipDate, List<ItemDetail> itemList)
{
this.cbJob = cbJob;
this.idNumber = idNumber;
this.shipDate = shipDate;
this.itemList = itemList;
}
public List<ItemDetail> getItemList()
{
return itemList;
}
public void setItemList(List<ItemDetail> itemList)
{
this.itemList = itemList;
}
/**
* @return the cbJob
*/
public Checkbox getCbJob() {
return cbJob;
}
/**
* @param cbJob the cbJob to set
*/
public void setCbJob(Checkbox cbJob) {
this.cbJob = cbJob;
}
/**
* @return the idNumber
*/
public String getIdNumber() {
return idNumber;
}
/**
* @param idNumber the idNumber to set
*/
public void setIdNumber(String idNumber) {
this.idNumber = idNumber;
}
/**
* @return the shipDate
*/
public LocalDate getShipDate() {
return shipDate;
}
/**
* @param shipDate the shipDate to set
*/
public void setShipDate(LocalDate shipDate) {
this.shipDate = shipDate;
}
}
OrderDetail 类（TreeTable 中的叶子）：
package info.chrismcgee.sky.production;
public class ItemDetail {
private String productId;
private String detail;
private long numColors;
private long numQuantity;
private PrintType printType;
private boolean active;
public ItemDetail(String productId, String detail, long numColors, long numQuantity, PrintType printType, boolean active)
{
this.productId = productId;
this.detail = detail;
this.numColors = numColors;
this.numQuantity = numQuantity;
this.printType = printType;
this.active = active;
}
/**
* @return the productId
*/
public String getProductId() {
return productId;
}
/**
* @param productId the productId to set
*/
public void setProductId(String productId) {
this.productId = productId;
}
/**
* @return the detail
*/
public String getDetail() {
return detail;
}
/**
* @param detail the detail to set
*/
public void setDetail(String detail) {
this.detail = detail;
}
/**
* @return the numColors
*/
public long getNumColors() {
return numColors;
}
/**
* @param numColors the numColors to set
*/
public void setNumColors(long numColors) {
this.numColors = numColors;
}
/**
* @return the numQuantity
*/
public long getNumQuantity() {
return numQuantity;
}
/**
* @param numQuantity the numQuantity to set
*/
public void setNumQuantity(long numQuantity) {
this.numQuantity = numQuantity;
}
/**
* @return the printType
*/
public PrintType getPrintType() {
return printType;
}
/**
* @param printType the printType to set
*/
public void setPrintType(PrintType printType) {
this.printType = printType;
}
/**
* @return the active
*/
public boolean isActive() {
return active;
}
/**
* @param active the active to set
*/
public void setActive(boolean active) {
this.active = active;
}
}
最后是 NoRootTreeTableModel 类，它扩展了 AbstractTreeTableModel 类，因此树的根不显示：
package info.chrismcgee.sky.production.treetable;
import info.chrismcgee.sky.production.ItemDetail;
import info.chrismcgee.sky.production.Job;
import java.util.List;
import org.jdesktop.swingx.treetable.AbstractTreeTableModel;
public class NoRootTreeTableModel extends AbstractTreeTableModel {
private final static String[] COLUMN_NAMES = {"Name/Product", "Job # / Detail", "T",
"Colors", "Quantity", "Total"};
private List<Job> jobList;
public NoRootTreeTableModel(List<Job> jobList)
{
super(new Object());
this.jobList = jobList;
}
@Override
public int getColumnCount() {
return COLUMN_NAMES.length;
}
@Override
public String getColumnName(int column)
{
return COLUMN_NAMES[column];
}
@Override
public boolean isCellEditable(Object node, int column)
{
return false;
}
@Override
public boolean isLeaf(Object node)
{
return node instanceof ItemDetail;
}
@Override
public int getChildCount(Object parent) {
if (parent instanceof Job) {
Job job = (Job) parent;
return job.getItemList().size();
}
return jobList.size();
}
@Override
public Object getChild(Object parent, int index) {
if (parent instanceof Job) {
Job job = (Job) parent;
return job.getItemList().get(index);
}
return jobList.get(index);
}
@Override
public int getIndexOfChild(Object parent, Object child) {
Job job = (Job) parent;
ItemDetail item = (ItemDetail) child;
return job.getItemList().indexOf(item);
}
@Override
public Object getValueAt(Object node, int column) {
if (node instanceof Job) {
Job job = (Job) node;
switch (column) {
case 0:
return job.getCbJob();
case 1:
return job.getIdNumber();
}
} else if (node instanceof ItemDetail) {
ItemDetail item = (ItemDetail) node;
switch (column) {
case 0:
return item.getProductId();
case 1:
return item.getDetail();
case 2:
return item.getPrintType();
case 3:
return item.getNumColors();
case 4:
return item.getNumQuantity();
case 5:
return item.getNumColors() * item.getNumQuantity();
}
}
return null;
}
}
我知道这是很多代码，但我想不出一种快速的方法来减少它并让它按照我需要的方式工作。实际上，它已经减少了很多。（我遗漏了一些通常也在那个 JFrame 中的东西。）
运行代码时，我没有得到分支的复选框；相反，我得到了似乎是复选框代码的字符串表示形式：
嗯？这是怎么发生的，更重要的是，我怎样才能让复选框显示出来？
