Class ColumnList

  • All Implemented Interfaces:
    java.util.EventListener, javax.swing.event.TableColumnModelListener

    public class ColumnList
    extends java.lang.Object
    implements javax.swing.event.TableColumnModelListener
    List reflecting the TableColumn objects in a TableColumnModel. Unlike a TableColumnModel, this never throws away any columns, it just maintains an array of flags to indicate which columns are currently in the model and which are not. On construction it registers itself as a listener on its ColumnModel so that it automatically keeps up to date with its state.
