Package	org.aswing.event
Class	public class TableModelEvent
Inheritance	TableModelEvent ModelEvent

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, 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 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.

Constructor detail

TableModelEvent

()

constructor

public function TableModelEvent(source:TableModel, firstRow:int = -2, lastRow:int = -2, column:int, type:String)

     TableModelEvent(source:TableModel, firstRow:int, lastRow:int, column:int, type:String)
     TableModelEvent(source:TableModel, firstRow:int, lastRow:int, column:int)
     TableModelEvent(source:TableModel, firstRow:int, lastRow:int)
     TableModelEvent(source:TableModel, row:int)
     TableModelEvent(source:TableModel)

TableModelEvent(source:TableModel, firstRow:int, lastRow:int, column:int, type:String)
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.
TableModelEvent(source:TableModel, firstRow:int, lastRow:int, column:int)
The cells in column column in the range [firstRow, lastRow] have been updated.
TableModelEvent(source:TableModel, firstRow:int, lastRow:int)
The data in rows [firstRow, lastRow] have been updated.
TableModelEvent(source:TableModel, row:int)
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(source: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. 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.

Parameters

	`source:TableModel`

	`firstRow:int` (default = `-2`)

	`lastRow:int` (default = `-2`)

	`column:int`

	`type:String`

Method detail

getColumn

()

method

public function getColumn():int

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

Returns

int

getFirstRow

()

method

public function getFirstRow():int

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

Returns

int

getLastRow

()

method

public function getLastRow():int

Returns the last row that changed.

Returns

int

getType

()

method

public function getType():String

Returns

String

Constant detail

HEADER_ROW

constant

public static const HEADER_ROW:int = -1

Identifies the header row.
