Constructor Detail

IlvTableModelEvent

public IlvTableModelEvent(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 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.

IlvTableModelEvent

public IlvTableModelEvent(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 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.

IlvTableModelEvent

public IlvTableModelEvent(TableModel source,
                          int firstRow,
                          int lastRow)

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

IlvTableModelEvent

public IlvTableModelEvent(TableModel source,
                          int firstRow,
                          int lastRow,
                          int column)

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

IlvTableModelEvent

public IlvTableModelEvent(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, BEFORE_UPDATE, UPDATE, BEFORE_DELETE and DELETE.

Method Detail

fireBeforeTableRowsDeleted

public static void fireBeforeTableRowsDeleted(AbstractTableModel model,
                                              int firstRow,
                                              int lastRow)

Notifies all listeners of the given AbstractTableModel that rows in the range [firstRow, lastRow], inclusive, are about to be deleted.

Parameters:

model - the table model

firstRow - the first row

lastRow - the last row

fireBeforeTableStructureChanged

public static void fireBeforeTableStructureChanged(AbstractTableModel model)

Notifies all listeners of the given AbstractTableModel that the table's structure is about to changed. The number of columns in the table, and the names and types of the new columns may be different from the previous state. If the JTable receives this event and its autoCreateColumnsFromModel flag is set it discards any table columns that it had and reallocates default columns in the order they appear in the model. This is the same as calling setModel(TableModel) on the JTable.

fireBeforeTableDataChanged

public static void fireBeforeTableDataChanged(AbstractTableModel model)

Notifies all listeners of the given AbstractTableModel that all cell values in the table's rows are about to changed. The number of rows may also be about to changed. The structure of the table (as in the order of the columns) is assumed to stay the same.
