Package uk.ac.starlink.topcat

Class RestrictedColumnComboBoxModel

  • All Implemented Interfaces:
    java.io.Serializable, java.util.EventListener, javax.swing.ComboBoxModel, javax.swing.event.TableColumnModelListener, javax.swing.ListModel
    public abstract class RestrictedColumnComboBoxModel
extends ColumnComboBoxModel
    Does a similar job as for ColumnComboBoxModel, but when only a subset of the available columns should show up in the combobox. Use it in the same way as ColumnComboBoxModel, but implement the acceptColumn(uk.ac.starlink.table.ColumnInfo) method appropriately. In the case that acceptColumn accepts everything, this will behave just the same as a ColumnComboBoxModel (though perhaps less efficiently).

        Returns a column combo box model which checks for compatibility with a given class. Class matching is not strict in the following sense: any numeric class (Number) is considered assignable to any other numeric class.
        Parameters:
        colModel - the column model
        hasNone - true if you want a NO_COLUMN entry
        clazz - the class that available columns have to have data assignable to
