Class RestrictedColumnComboBoxModel

java.lang.Object

javax.swing.AbstractListModel<TableColumn>

uk.ac.starlink.topcat.ColumnComboBoxModel

uk.ac.starlink.topcat.RestrictedColumnComboBoxModel

All Implemented Interfaces:

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

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).

Method Detail

acceptColumn

public abstract boolean acceptColumn(uk.ac.starlink.table.ColumnInfo cinfo)

Determines whether a column with given metadata in the column model should show up in the combobox.

Parameters:

cinfo - column metadata to assess

Returns:

true iff the column is to be used

getElementAt

public TableColumn getElementAt(int index)

Specified by:

getElementAt in interface ListModel<TableColumn>

Overrides:

getElementAt in class ColumnComboBoxModel

getSize

public int getSize()

Specified by:

getSize in interface ListModel<TableColumn>

Overrides:

getSize in class ColumnComboBoxModel

columnAdded

public void columnAdded(TableColumnModelEvent evt)

Specified by:

columnAdded in interface TableColumnModelListener

Overrides:

columnAdded in class ColumnComboBoxModel

columnRemoved

public void columnRemoved(TableColumnModelEvent evt)

Specified by:

columnRemoved in interface TableColumnModelListener

Overrides:

columnRemoved in class ColumnComboBoxModel

columnMoved

public void columnMoved(TableColumnModelEvent evt)

Specified by:

columnMoved in interface TableColumnModelListener

Overrides:

columnMoved in class ColumnComboBoxModel

makeClassColumnComboBoxModel

public static RestrictedColumnComboBoxModel makeClassColumnComboBoxModel(TableColumnModel colModel,
                                                                         boolean hasNone,

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
