 class SwingTableCellEditor
extends javax.swing.AbstractCellEditor
implements javax.swing.table.TableCellEditor

A specialized cell editor class for Swing tables.

This class is used as editor class for table columns that define a custom editor. The component that is used as editor is obtained from the TableTag defining the table. Together with the special table model and the Form instance constructed for the table the current values are transfered into the editor component and input validation can be performed.

An instance of this class is responsible for a complete table. The editor component to be used is obtained from the table definition based on the given column index. Setting and retrieving the editor's values is of less importance because this is handled by the table's editor form object.

Constructor Detail

SwingTableCellEditor

public SwingTableCellEditor(SwingTableModel tabModel)

Creates a new instance of SwingTableCellEditor and sets the associated table model.

Parameters:

tabModel - the table model

Method Detail

getModel

public SwingTableModel getModel()

Returns a reference to the associated table model.

Returns:

the table model

getTableCellEditorComponent

public java.awt.Component getTableCellEditorComponent(javax.swing.JTable table,
                                                      java.lang.Object value,
                                                      boolean selected,
                                                      int row,
                                                      int col)

Returns the editor component for the specified cell. This implementation will return the editor component that was specified in the table definition.

Specified by:

getTableCellEditorComponent in interface javax.swing.table.TableCellEditor

Parameters:

table - the affected table

value - the current value of this cell

selected - a flag if the cell is highlighted

row - the row index

col - the column index

Returns:

the editor component to be used

getCellEditorValue

public java.lang.Object getCellEditorValue()

Returns the current value of this editor. This implementation just returns null. The value will be processed by the table's editor form and directly written into the table model.

Specified by:

getCellEditorValue in interface javax.swing.CellEditor

Returns:

the editor's current value

stopCellEditing

public boolean stopCellEditing()

Tests whether editing can be stopped. This implementation performs validation of the user input.

Specified by:

stopCellEditing in interface javax.swing.CellEditor

Overrides:

stopCellEditing in class javax.swing.AbstractCellEditor

Returns:

a flag if editing can be stopped (this is the case if the input is valid)
