我用JTable创建了一个窗口，其中包含有关某些用户的文本文件中的值。 另外，还有用于创建，编辑和删除用户的按钮。 我想使用并打开相同的“创建和编辑”按钮窗口，但是如果单击“编辑”按钮，则应使用JTable中的高亮（单击）用户的值填充窗口。
//PatientWindow.java
private void initActions() {
btnCreate.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
CreateEditPatientWindow createEditPatientWindow = new CreateEditPatientWindow();
createEditPatientWindow.setVisible(true);
}
});
btnUpdate.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
int row = tblPatients.getSelectedRow();
if(row == -1)
{
JOptionPane.showMessageDialog(null, "You must select row for update", "Info", JOptionPane.WARNING_MESSAGE);
}
else
{
DefaultTableModel model = (DefaultTableModel)tblPatients.getModel();
String username = model.getValueAt(row, 6).toString();
UserModel userSearch = UsersClass.findUser(username);
if(userSearch != null)
{
//System.out.println("USER FOUND!!!" + username);
//PatientModel patientModel = patient;
//patientModel.setUsername(username);
CreateEditPatientWindow createEditPatientWindow = new CreateEditPatientWindow(USE VALUES OF SELECTED USER);
createEditPatientWindow.setVisible(true);
}
else
{
JOptionPane.showMessageDialog(null, "User not found", "Info", JOptionPane.ERROR_MESSAGE);
}
}
}
});
}
private void initGUI() {
tbToolBar = new JToolBar();
btnCreate = new JButton("Create");
btnUpdate = new JButton("Update");
btnDelete = new JButton("Delete");
tbToolBar.add(btnCreate);
tbToolBar.add(btnUpdate);
tbToolBar.add(btnDelete);
spScroll = new JScrollPane();
ArrayList<PatientModel> patientsList = UsersClass.getPatients();
String[] header = new String[] {
"Name",
"Lastname",
"UMCN",
"Gender",
"Adress",
"Phone number",

//"User type",
"Insurance number",
"Insurance category",
"Expiry date"};
Object[][] body = new Object[patientsList.size()][header.length];
int a = 0;
for(int i = 0; i < patientsList.size(); i++)
{
PatientModel patientsData = patientsList.get(i);
body[i][0] = patientsData.getName();
body[i][1] = patientsData.getLastname();
body[i][2] = patientsData.getUmcn();

这里还有UsersClass，其中包含用于用各种类型的用户（患者，护士，医生等）填充Array的方法。

答案 0 :(得分：0)
我建议您：
为“用户”对象创建自定义TableModel。有关如何执行此操作的分步示例，请参见Row Table Model。
然后，当您创建弹出对话框时，将“用户”对象传递给对话框。如果单击“新建”按钮，则会传入一个空的“用户”对象。如果单击“编辑”按钮，则会从自定义TableModel中获得“用户”对象
对话框类中的代码，然后简单地显示“ User”对象中的数据。
然后，当对话框关闭时，您需要使用在对话框文本字段中输入的数据来更新“用户”对象。如果单击“编辑”，则只需重新绘制表以查看新数据。如果单击“新建”，则将用户对象添加到TableModel。
