Moves one or more rows from the inclusive range start to end to the to position in the model. After the move, the row that was at index start will be at index to. This method will send a tableChanged notification message to all the listeners.

   Examples of moves:
   
   1. moveRow(1,3,5);
     a|B|C|D|e|f|g|h|i|j|k   - before
     a|e|f|g|h|B|C|D|i|j|k   - after

newDataAvailable

()

method

public function newDataAvailable(event:TableModelEvent):void

Equivalent to fireTableChanged.

Parameters

event:TableModelEvent — the change event

newRowsAdded

public function rowsRemoved(e:TableModelEvent):void

Equivalent to fireTableChanged.

Parameters

e:TableModelEvent — the change event

Parameters

editable:Boolean — editable or not

setColumnCount

()

method

public function setColumnCount(columnCount:int):void

Sets the number of columns in the model. If the new size is greater than the current size, new columns are added to the end of the model with null cell values. If the new size is less than the current size, all columns at index columnCount and greater are discarded.

If the number of columnNamess is less than the current number of columns, all the extra columns at the end of a row are discarded.

Parameters

columnNames:Array — columnNames array of column names. If null, set the model to zero columns

See also

setNumRows()

setData

()

method

public function setData(dataArray:Array):void

Replaces the current dataArray instance variable with the new Vector of rows, dataArray. Each row is represented in dataArray as a Vector of Object values.

Note that passing in a null value for dataArray results in unspecified behavior, an possibly an exception. Parameters

dataArray:Array — dataArray the new data vector

See also

getData()

setDataNames

()

method

public function setDataNames(dataArray:Array, columnNames:Array):void

Replaces the current dataArray instance variable with the new Vector of rows, dataArray. Each row is represented in dataArray as a Vector of Object values.

columnNames are the names of the new columns. The first name in columnNames is mapped to column 0 in dataArray. Each row in dataArray is adjusted to match the number of columns in columnNames either by truncating the Vector if it is too long, or adding null values if it is too short.

Note that passing in a null value for dataArray results in unspecified behavior, an possibly an exception. Parameters

	`dataArray:Array` — dataArray the new data vector

	`columnNames:Array` — columnNames the names of the columns

See also

getData()

setNumRows

()

method

public function setNumRows(rowCount:int):void

Obsolete as of Java 2 platform v1.3. Please use setRowCount instead.

Parameters

rowCount:int

setRowCount

()

method

public function setRowCount(rowCount:int):void

Sets the number of rows in the model. If the new size is greater than the current size, new rows are added to the end of the model If the new size is less than the current size, all rows at index rowCount and greater are discarded.

Parameters

rowCount:int

setColumnCount()

setValueAt

()

method

public override function setValueAt(aValue:*, row:int, column:int):void

Sets the object value for the cell at column and row. aValue is the new value. This method will generate a tableChanged notification.
