Class HidableTableColumnModel

  • All Implemented Interfaces:
    PropertyChangeListener, Serializable, EventListener, ListSelectionListener, TableModelListener, TableColumnModel
    public class HidableTableColumnModel
extends DefaultTableColumnModel
implements TableModelListener
    HidableTableColumnModel 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 whether you want invisible columns taken into account.
