All Implemented Interfaces:

Serializable, CellEditor, TableCellEditor

public class ValueModelTableCellEditor
extends AbstractCellEditor
implements TableCellEditor

TableCellEditor that uses a backing FormModel to determine the editing capabilities and committing of the value.

NOTE: the CellEditor will get the first event, only afterwards the row selection changes. This has the effect that editing a cell will switch values upon entering. Additionally the cell should always be marked editable and the binding that acts as the editor should disable itself if needed. If we were to rely on FieldMetadata.isReadOnly(), the previous value would determine if the cell is editable because the underlying form object isn't changed yet.

Constructor Detail

ValueModelTableCellEditor

public ValueModelTableCellEditor(FormModel formModel,
                                 String propertyName,
                                 JComponent editor)

Creates a TableCellEditor. The property will be used to retrieve the ValueModel and FieldMetadata. The first is used while getting the initial value, the latter is used to determine if the cell is editable. Note that the given editor should be bound already.

Parameters:

formModel - model to use when committing/reverting.

propertyName - name of the property.

editor - JComponent bound to that property used in the editable state.

                                 FieldMetadata fieldMetadata,
                                 ValueModel valueModel,
                                 JComponent editor,
                                 ActionCommand commitCommand)

Creates a TableCellEditor. The ValueModel is used while getting the initial value, the FieldMetadata is used to determine if the cell is editable. Note that the given editor should be bound already.

Parameters:

formModel - model to use when committing/reverting.

valueModel - valueModel to retrieve the initial value.

fieldMetadata - metaData to determine if the cell is editable.

editor - JComponent bound to that property used in the editable state.

Method Detail

getTableCellEditorComponent

public Component getTableCellEditorComponent(JTable table,
                                             Object value,
                                             boolean isSelected,
                                             int row,
                                             int column)

Specified by:

getTableCellEditorComponent in interface TableCellEditor

cancelCellEditing

public void cancelCellEditing()

Specified by:

cancelCellEditing in interface CellEditor

Overrides:

cancelCellEditing in class AbstractCellEditor

getCellEditorValue

public Object getCellEditorValue()

Specified by:

getCellEditorValue in interface CellEditor

isCellEditable

public boolean isCellEditable(EventObject anEvent)

We cannot rely on the FieldMetadata because the form object is replaced AFTER this method is queried. We would be returning the previous value instead of the current one. Instead rely on the binding's component to set the editor read-only.

Specified by:

isCellEditable in interface CellEditor

Overrides:

isCellEditable in class AbstractCellEditor

stopCellEditing

public boolean stopCellEditing()

Specified by:

stopCellEditing in interface CellEditor

Overrides:

stopCellEditing in class AbstractCellEditor
