Constructor Detail

TableModelEvent

public TableModelEvent(javax.swing.table.TableModel source)

Suppressed: 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 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.

TableModelEvent

public TableModelEvent(javax.swing.table.TableModel source,
                       int row)

Suppressed: 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 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.

TableModelEvent

public TableModelEvent(javax.swing.table.TableModel source,
                       int firstRow,
                       int lastRow)

Suppressed: The data in rows [firstRow, lastRow] have been updated.

TableModelEvent

public TableModelEvent(javax.swing.table.TableModel source,
                       int firstRow,
                       int lastRow,
                       int column)

Suppressed: The cells in column column in the range [firstRow, lastRow] have been updated.

TableModelEvent

public TableModelEvent(javax.swing.table.TableModel source,
                       int firstRow,
                       int lastRow,
                       int column,
                       int type)

Suppressed: 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.

Method Detail

getFirstRow

public int getFirstRow()

Enabled: Returns the first row that changed. HEADER_ROW means the meta data, ie. names, types and order of the columns.

getLastRow

public int getLastRow()

Enabled: Returns the last row that changed.

getColumn

public int getColumn()

Enabled: Returns the column for the event. If the return value is ALL_COLUMNS; it means every column in the specified rows changed.
