Class ColumnComboBoxModel

java.lang.Object

javax.swing.AbstractListModel<TableColumn>

uk.ac.starlink.topcat.ColumnComboBoxModel

All Implemented Interfaces:

Serializable, EventListener, ComboBoxModel<TableColumn>, TableColumnModelListener, ListModel<TableColumn>

Direct Known Subclasses:

RestrictedColumnComboBoxModel

public class ColumnComboBoxModel
extends AbstractListModel<TableColumn>
implements TableColumnModelListener, ComboBoxModel<TableColumn>

Adaptor class which turns a TableColumnModel into a ComboBoxModel. This model is designed to reflect the contents of a column model rather than the other way around, so in general you wouldn't want to add a ListDataListener to this model, you'd add it to the underlying column model.

Selections in the column model are not reflected by selections in this model, but columns added/moved/removed are.
