java - 获取更新的 JTable 值

Question

我正在尝试使用 JTable 来更新 Java SWING 应用程序中的用户，目前当我编辑一个单元格时，只有当我单击另一个单元格从而触发 tableModelListener 时才能获得编辑结果。我希望能够在不单击其他单元格的情况下在按钮事件中获取这些更改的值。

我的表格定义:

DefaultTableModel tableModel = new DefaultTableModel();

table = new JTable(tableModel);

tableModel.addColumn("Key");
tableModel.addColumn("Value");

if (PatientView.getSelected() != null){
    tableModel.addRow(new Object[]{"Name", PatientView.getSelected().getName()});
    tableModel.addRow(new Object[]{"Age", PatientView.getSelected().getAge()});
    tableModel.addRow(new Object[]{"Height", PatientView.getSelected().getHeight()});
    tableModel.addRow(new Object[]{"Weight", PatientView.getSelected().getWeight()});
    tableModel.addRow(new Object[]{"BMI", PatientView.getSelected().getCalculatedBMI()});

}

表监听器

tableModel.addTableModelListener(new TableModelListener(){
            @Override
            public void tableChanged(TableModelEvent arg0) {
                int row = arg0.getFirstRow();
                int column = arg0.getColumn();
                Object data = tableModel.getValueAt(0, 1);
                System.out.println(data);
            }
        });

按钮 Action 监听器

okButton.addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent arg0) {
                        Vector data = tableModel.getDataVector();
                        System.out.println(table.getValueAt(0, 1));
                        System.out.println(data);
                    }
                });

I want to be able to get these changed values on a button event without clicking other cells.
