public class XTableColumnModel
extends DefaultTableColumnModel

XTableColumnModel extends the DefaultTableColumnModel . It provides a comfortable way to hide/show columns. Columns keep their positions when hidden and shown again. In order to work with JTable it cannot add any events to TableColumnModelListener. Therefore hiding a column will result in columnRemoved event and showing it again will notify listeners of a columnAdded, and possibly a columnMoved event. For the same reason the following methods still deal with visible columns only: getColumnCount(), getColumns(), getColumnIndex(), getColumn() There are overloaded versions of these methods that take a parameter onlyVisible which let's you specify wether you want invisible columns taken into account.

Field Detail

allTableColumns

protected Vector<TableColumn> allTableColumns

Array of TableColumn objects in this model. Holds all column objects, regardless of their visibility

Method Detail

setColumnVisible

public void setColumnVisible(TableColumn column,
                             boolean visible)

Sets the visibility of the specified TableColumn. The call is ignored if the TableColumn is not found in this column model or its visibility status did not change.

Parameters:

column - the column to show/hide

visible - its new visibility status

setAllColumnsVisible

public void setAllColumnsVisible()

Makes all columns in this model visible

getColumnByModelIndex

public TableColumn getColumnByModelIndex(int modelColumnIndex)

Maps the index of the column in the table model at modelColumnIndex to the TableColumn object. There may me multiple TableColumn objects showing the same model column, though this is uncommon. This method will always return the first visible or else the first invisible column with the specified index.

Parameters:

modelColumnIndex - index of column in table model

Returns:

table column object or null if no such column in this column model

isColumnVisible

public boolean isColumnVisible(TableColumn aColumn)

Checks wether the specified column is currently visible.

Parameters:

aColumn - column to check

Returns:

visibility of specified column (false if there is no such column at all. [It's not visible, right?])

addColumn

public void addColumn(TableColumn column)

Append column to the right of exisiting columns. Posts columnAdded event.

Specified by:

addColumn in interface TableColumnModel

Overrides:

addColumn in class DefaultTableColumnModel

Parameters:

column - The column to be added

Throws:

IllegalArgumentException - if column is null

See Also:

removeColumn(javax.swing.table.TableColumn)

removeColumn

public void removeColumn(TableColumn column)

Removes column from this column model. Posts columnRemoved event. Will do nothing if the column is not in this model.

Specified by:

removeColumn in interface TableColumnModel

Overrides:

removeColumn in class DefaultTableColumnModel

Parameters:

column - the column to be added

See Also:

addColumn(javax.swing.table.TableColumn)

moveColumn

public void moveColumn(int oldIndex,
                       int newIndex)

Moves the column from oldIndex to newIndex. Posts columnMoved event. Will not move any columns if oldIndex equals newIndex.

Specified by:

moveColumn in interface TableColumnModel

Overrides:

moveColumn in class DefaultTableColumnModel

Parameters:

oldIndex - index of column to be moved

newIndex - new index of the column

Throws:

IllegalArgumentException - if either oldIndex or newIndex are not in [0, getColumnCount() - 1]

getColumnCount

public int getColumnCount(boolean onlyVisible)

Returns the total number of columns in this model.

Parameters:

onlyVisible - if set only visible columns will be counted

Returns:

the number of columns in the tableColumns array

See Also:

getColumns(boolean)

getColumns

public Enumeration<TableColumn> getColumns(boolean onlyVisible)

Returns an Enumeration of all the columns in the model.

Parameters:

onlyVisible - if set all invisible columns will be missing from the enumeration.

Returns:

an Enumeration of the columns in the model

getColumnIndex

public int getColumnIndex(Object identifier,
                          boolean onlyVisible)

Returns the position of the first column whose identifier equals identifier. Position is the the index in all visible columns if onlyVisible is true or else the index in all columns.

Parameters:

identifier - the identifier object to search for

onlyVisible - if set searches only visible columns

Returns:

the index of the first column whose identifier equals identifier

Throws:

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

See Also:

getColumn(int, boolean)

getColumn

public TableColumn getColumn(int columnIndex,
                             boolean onlyVisible)

Returns the TableColumn object for the column at columnIndex.

Parameters:

columnIndex - the index of the column desired

onlyVisible - if set columnIndex is meant to be relative to all visible columns only else it is the index in all columns

Returns:

the TableColumn object for the column at columnIndex
