Class DefaultCellEditor

java.lang.Object

javax.swing.AbstractCellEditor

vaadinx.swing.DefaultCellEditor

All Implemented Interfaces:

Serializable, CellEditor, TableCellEditor, TreeCellEditor

public class DefaultCellEditor
extends AbstractCellEditor
implements TableCellEditor, TreeCellEditor

Port of DefaultCellEditor — the stock cell editor over a JTextField, JComboBox, or JCheckBox. Body ported faithfully (R_swing_is_truth) from the JDK class: same three ctors, same EditorDelegate shape, same clickCountToStart defaults (2 for text field, 1 for combo and check box).

Layering: this is an emulator-only type (confirmed 2026-07-07, see D_jtable_cell_editing in emulators/decisions.md). It is inherently stage-2 / Swing-shaped — its ctors take emulator components and getTableCellEditorComponent(JTable, Object, boolean, int, int) returns Component. Stage-3 (pure-surrogate) code edits via the Vaadin Grid.Editor that SJTable inherits, not through this class.

Reuse boundary: extends the JDK AbstractCellEditor (which references no java.awt.Component, so it is reused unchanged per D_whitelist_porting — it carries the CellEditorListener list + fireEditingStopped/fireEditingCanceled plumbing) and implements the ported TableCellEditor + TreeCellEditor.

The EditorDelegate registers itself as an ActionListener on the editor component; because the emulator JTextField/JComboBox/JCheckBox fire real Swing ActionEvents via their R_swing_is_truth peer bridges, a commit on the editor component (JTextField Enter, combo selection) fans out to the CellEditorListeners with no Grid involved — which is what lets this class be unit-tested in isolation ahead of the JTable Grid.Editor bridge.

Field Details

editorComponent

protected JComponent editorComponent

The editing component; set by one of the three type-specific ctors.

delegate

protected DefaultCellEditor.EditorDelegate delegate

Bridges the editor component's value in/out and translates its action/item events into stopCellEditing calls. A type-specific subclass instance is created by each ctor.

clickCountToStart

protected int clickCountToStart

Clicks needed to start editing: 2 for a text field, 1 for combo/check box.

getTableCellEditorComponent

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

Description copied from interface: TableCellEditor

Returns the component to use for editing the cell at row/column, seeded with value. Called by the JTable editing bridge when a cell enters edit mode; the returned component's peer is what the underlying Vaadin Grid.Editor shows.

Specified by:

getTableCellEditorComponent in interface TableCellEditor

getTreeCellEditorComponent

public Component getTreeCellEditorComponent(JTree tree,
 Object value,
 boolean isSelected,
 boolean expanded,
 boolean leaf,
 int row)

Description copied from interface: TreeCellEditor

Never invoked — in-cell editing is deferred (D_gap_severity_triage sub-bucket (b)).

Specified by:

getTreeCellEditorComponent in interface TreeCellEditor
