Class DefaultCellEditor.EditorDelegate

protected class DefaultCellEditor.EditorDelegate extends Object implements ActionListener, ItemListener, Serializable

This changeable module access the editor component in the component specific way. For instance, to set the value for JTextField, we need to call setText(String), and for JCheckBox we need to call setSelected(boolean). Each default editor has the component specific derivative of this class. These derivatives are private inner classes of the DefaultCellEditor. The editor delegate is also set for the editor component as the action listener. It listens for the events that indicate that editing has stopped.
