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. Please see XMLEncoder

will repaint the entire visible region on receiving this event, querying the model for the cell values that are visible. The structure of the table ie, the column names, types and order have not changed.source

HEADER_ROW
as the value for the row
. When the JTable
receives this event and its autoCreateColumnsFromModel
flag is set it discards any TableColumns that it had and reallocates default ones in the order they appear in the model. This is the same as calling setModel(TableModel)
on the JTable
