Method Detail

addColumn

public void addColumn(TableColumn aColumn)

Appends aColumn to the end of the receiver's tableColumns array. This method also posts the columnAdded() event to its listeners.

Parameters:

aColumn - The TableColumn to be added

removeColumn(javax.swing.table.TableColumn)

removeColumn

public void removeColumn(TableColumn column)

Deletes the TableColumn column from the receiver's table columns array. This method will do nothing if column is not in the table's columns list. This method also posts the columnRemoved() event to its listeners.

Parameters:

column - The TableColumn to be removed

See Also:

addColumn(javax.swing.table.TableColumn)

moveColumn

public void moveColumn(int columnIndex,
                       int newIndex)

Moves the column and heading at columnIndex to newIndex. The old column at columnIndex will now be found at newIndex, The column that used to be at newIndex is shifted left or right to make room. This will not move any columns if columnIndex equals newIndex. This method also posts the columnMoved() event to its listeners.

Parameters:

columnIndex - the index of column to be moved

newIndex - New index to move the column

Throws:

IllegalArgumentException - if column or newIndex are not in the valid range

setColumnMargin

public void setColumnMargin(int newMargin)

Sets the TableColumn's column margin to newMargin. This method also posts the columnMarginChanged() event to its listeners.

Parameters:

newMargin - the width margin of the column

See Also:

getColumnMargin()

getColumnCount

public int getColumnCount()

Returns the number of columns in the model

getColumns

public Enumeration getColumns()

Returns an Enumeration of all the columns in the model

getColumnIndex

public int getColumnIndex(Object columnIdentifier)

Returns the index of the first column in the receiver's columns array whose identifier is equal to identifier, when compared using equals().

Parameters:

identifier - the identifier object

Returns:

the index of the first table column in the receiver's tableColumns array whose identifier is equal to identifier, when compared using equals().

Throws:

IllegalArgumentException - if identifier is null or no TableColumn has this identifier
