• java.lang.Object
  • javax.swing.AbstractCellEditor

Fields Summary
protected JComponent	editorComponent The Swing component being edited.
protected EditorDelegate	delegate The delegate class which handles all methods sent from the CellEditor.
protected int	clickCountToStart An integer specifying the number of clicks needed to start editing. Even if clickCountToStart is defined as zero, it will not initiate until a click occurs.

Constructors Summary
public DefaultCellEditor(JTextField textField) Constructs a DefaultCellEditor that uses a text field. param textField a JTextField object // // Constructors // editorComponent = textField; this.clickCountToStart = 2; delegate = new EditorDelegate() { public void setValue(Object value) { textField.setText((value != null) ? value.toString() : ""); } public Object getCellEditorValue() { return textField.getText(); } }; textField.addActionListener(delegate);
public DefaultCellEditor(JCheckBox checkBox) Constructs a DefaultCellEditor object that uses a check box. param checkBox a JCheckBox object editorComponent = checkBox; delegate = new EditorDelegate() { public void setValue(Object value) { boolean selected = false; if (value instanceof Boolean) { selected = ((Boolean)value).booleanValue(); } else if (value instanceof String) { selected = value.equals("true"); } checkBox.setSelected(selected); } public Object getCellEditorValue() { return Boolean.valueOf(checkBox.isSelected()); } }; checkBox.addActionListener(delegate); checkBox.setRequestFocusEnabled(false);
public DefaultCellEditor(JComboBox comboBox) Constructs a DefaultCellEditor object that uses a combo box. param comboBox a JComboBox object editorComponent = comboBox; comboBox.putClientProperty("JComboBox.isTableCellEditor", Boolean.TRUE); delegate = new EditorDelegate() { public void setValue(Object value) { comboBox.setSelectedItem(value); } public Object getCellEditorValue() { return comboBox.getSelectedItem(); } public boolean shouldSelectCell(EventObject anEvent) { if (anEvent instanceof MouseEvent) { MouseEvent e = (MouseEvent)anEvent; return e.getID() != MouseEvent.MOUSE_DRAGGED; } return true; } public boolean stopCellEditing() { if (comboBox.isEditable()) { // Commit edited value. comboBox.actionPerformed(new ActionEvent( DefaultCellEditor.this, 0, "")); } return super.stopCellEditing(); } }; comboBox.addActionListener(delegate);
