java - How to remove a row in JTable via pressing on DELETE on the keyboard

Question

I know that I can use KeyListener to check if DELETE (char) 127 is pressed or not, but how can I add keyListener to the selectedRow in JTable?

EDIT:

I have tried this but it doesn't work:

myTable.addKeyListener(this);
...
public void keyPressed(KeyEvent e)
{
    if(e.getKeyCode() == 127 && myTable.GetSelectedRow() != -1)
    {
        btnRemove.doClick(); // this will remove the selected row in JTable
    }
}

One issue with KeyListeners is that the component being listened to must have the focus. One way to get around this is to use Key Bindings.

e.g.,

  // assume JTable is named "table"
  int condition = JComponent.WHEN_IN_FOCUSED_WINDOW;
  InputMap inputMap = table.getInputMap(condition);
  ActionMap actionMap = table.getActionMap();

  // DELETE is a String constant that for me was defined as "Delete"
  inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0), DELETE);
  actionMap.put(DELETE, new AbstractAction() {
     public void actionPerformed(ActionEvent e) {
        // TODO: do deletion action here
     }
  });
