public class TableModelEvent
extends EventObject
TableModelEvent is used to notify listeners that a table model has changed. The model event describes changes to a TableModel and all references to rows and columns are in the co-ordinate system of the model. Depending on the parameters used in the constructors, the TableModelevent can be used to specify the following types of changes: 

 TableModelEvent(source);              //  The data, ie. all rows changed 
 TableModelEvent(source, HEADER_ROW);  //  Structure change, reallcoate 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 deleted
It 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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

Constructor Index

o TableModelEvent(TableModel)
All row data in the table has changed, listeners should discard any state that was based on the rows and requery the TableModel to get the new row count and all the appropriate values.
o TableModelEvent(TableModel, int)
This row of data has been updated.
o TableModelEvent(TableModel, int, int)
The data in rows [firstRow, lastRow] have been updated.
o TableModelEvent(TableModel, int, int, int)
The cells in column column in the range [firstRow, lastRow] have been updated.
o TableModelEvent(TableModel, int, int, int, int)
The cells from (firstRow, column) to (lastRow, column) have been changed.

Constructors

o TableModelEvent 
 public TableModelEvent(TableModel source)
All row data in the table has changed, listeners should discard any state that was based on the rows and requery the TableModel to get the new row count and all the appropriate values. The JTable will repaint the entire visible region on recieving this event, querying the model for the cell values that are visble. The structure of the table ie, the column names, types and order have not changed.

o TableModelEvent 
 public TableModelEvent(TableModel source,
                        int row)
This row of data has been updated. To denote the arrival of a completely new table with a different structure use HEADER_ROW as the value for the row. When the JTable recieves 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.

o TableModelEvent 
 public TableModelEvent(TableModel source,
                        int firstRow,
                        int lastRow)
The data in rows [firstRow, lastRow] have been updated.

o TableModelEvent 
 public TableModelEvent(TableModel source,
                        int firstRow,
                        int lastRow,
                        int column)
The cells in column column in the range [firstRow, lastRow] have been updated.

o TableModelEvent 
 public TableModelEvent(TableModel source,
                        int firstRow,
                        int lastRow,
                        int column,
                        int type)
The cells from (firstRow, column) to (lastRow, column) have been changed. The column refers to the column index of the cell in the model's co-ordinate system. When column is ALL_COLUMNS, all cells in the specified range of rows are considered changed.

The type should be one of: INSERT, UPDATE and DELETE.

Methods

o getFirstRow 
 public int getFirstRow()
Returns the first row that changed. HEADER_ROW means the meta data, ie. names, types and order of the columns.

o getLastRow 
 public int getLastRow()
Returns the last row that changed.

o getColumn 
 public int getColumn()
Returns the column for the event. If the return value is ALL_COLUMNS; it means every column in the specified rows changed.

o getType 
 public int getType()
Returns the type of event - one of: INSERT, UPDATE and DELETE.
