public class TableModelEvent extends EventObject
TableModelEvent(source); // The data, ie. all rows changed TableModelEvent(source, HEADER_ROW); // Structure change, reallocate TableColumns TableModelEvent(source, 1); // Row 1 changed TableModelEvent(source, 3, 6); // Rows 3 to 6 inclusive changed TableModelEvent(source, 2, 2, 6); // Cell at (2, 6) changed TableModelEvent(source, 3, 6, ALL_COLUMNS, INSERT); // Rows (3, 6) were inserted TableModelEvent(source, 3, 6, ALL_COLUMNS, DELETE); // Rows (3, 6) were deletedIt is possible to use other combinations of the parameters, not all of them are meaningful. By subclassing, you can add other information, for example: whether the event WILL happen or DID happen. This makes the specification of rows in DELETE events more useful but has not been included in the swing package as the JTable only needs post-event notification.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeans™
has been added to the java.beans package.
