How can i add an UndoableEditListener to JTable cells?

Question

Can i add an UndoableEditListener to a JTable? For example with a JTextField we do this :

textField = new JTextField();
      Document doc = textField.getDocument();
      doc.addUndoableEditListener(new MyUndoableEditListener());

Answer 1

You can do that for CellEditor of the JTabel in next way:

use DefaultCellEditor with JTextField :

JTextField field = new JTextField();
field.getDocument().addUndoableEditListener(new UndoableEditListener() {

    @Override
    public void undoableEditHappened(UndoableEditEvent arg0) {
        System.out.println("profit");
    }
});
DefaultCellEditor editor = new DefaultCellEditor(field);
table.getColumnModel().getColumn(COLUMN_INDEX).setCellEditor(editor);

table is your JTable and COLUMN_INDEX index of needed column.

Answer 2

No one stop use to assign this listener to the Document of of Text Field cell editor of JTable :) For your table use a custom cell editor, implement the UndoableEditListener to the editor's text component's Document.
