get edited value of cell in JTable after a button clicked

Question

当我点击名为“save”的按钮时，如何在我的JTable中获取单元格的编辑值？

Answer 1

New value can be get from the DefaultCellEditor .

    button.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {

            if (table.getCellEditor() != null) {
                DefaultCellEditor cellEditor = (DefaultCellEditor) table.getCellEditor();
                String value = ((JTextField) cellEditor.getComponent()).getText();
            }

        }
    });

Answer 2

Maybe this solution will be sufficient for you:

table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);

It saves all table data not only when "save" button is clicked, but also in other cases of focus change.
