copied!<p>I would recreate your DS once the user is finised editing the table.</p> <p>You can always create a custom editor to display a popup dialog where you have two separate text fields for each value of the range. Then you can edit each field as a double value within your specified range and recreate the formatted string before saving it to the model. Here's an old example I have lying around to get you started:</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.table.*; /* * The editor button that brings up the dialog. */ //public class TablePopupEditor extends AbstractCellEditor public class TablePopupEditor extends DefaultCellEditor implements TableCellEditor { private PopupDialog popup; private String currentText = ""; private JButton editorComponent; public TablePopupEditor() { super(new JTextField()); setClickCountToStart(2); // Use a JButton as the editor component editorComponent = new JButton(); editorComponent.setBackground(Color.white); editorComponent.setBorderPainted(false); editorComponent.setContentAreaFilled( false ); // Set up the dialog where we do the actual editing popup = new PopupDialog(); } public Object getCellEditorValue() { return currentText; } public Component getTableCellEditorComponent( JTable table, Object value, boolean isSelected, int row, int column) { SwingUtilities.invokeLater(new Runnable() { public void run() { System.out.println("run"); popup.setText( currentText ); // popup.setLocationRelativeTo( editorComponent ); Point p = editorComponent.getLocationOnScreen(); popup.setLocation(p.x, p.y + editorComponent.getSize().height); popup.show(); fireEditingStopped(); } }); currentText = value.toString(); editorComponent.setText( currentText ); return editorComponent; } /* * Simple dialog containing the actual editing component */ class PopupDialog extends JDialog implements ActionListener { private JTextArea textArea; public PopupDialog() { super((Frame)null, "Change Description", true); textArea = new JTextArea(5, 20); textArea.setLineWrap( true ); textArea.setWrapStyleWord( true ); KeyStroke keyStroke = KeyStroke.getKeyStroke("ENTER"); textArea.getInputMap().put(keyStroke, "none"); JScrollPane scrollPane = new JScrollPane( textArea ); getContentPane().add( scrollPane ); JButton cancel = new JButton("Cancel"); cancel.addActionListener( this ); JButton ok = new JButton("Ok"); ok.setPreferredSize( cancel.getPreferredSize() ); ok.addActionListener( this ); JPanel buttons = new JPanel(); buttons.add( ok ); buttons.add( cancel ); getContentPane().add(buttons, BorderLayout.SOUTH); pack(); getRootPane().setDefaultButton( ok ); } public void setText(String text) { textArea.setText( text ); } /* * Save the changed text before hiding the popup */ public void actionPerformed(ActionEvent e) { if ("Ok".equals( e.getActionCommand() ) ) { currentText = textArea.getText(); } textArea.requestFocusInWindow(); setVisible( false ); } } public static void main(String[] args) { String[] columnNames = {"Item", "Description"}; Object[][] data = { {"Item 1", "Description of Item 1"}, {"Item 2", "Description of Item 2"}, {"Item 3", "Description of Item 3"} }; JTable table = new JTable(data, columnNames); table.getColumnModel().getColumn(1).setPreferredWidth(300); table.setPreferredScrollableViewportSize(table.getPreferredSize()); JScrollPane scrollPane = new JScrollPane(table); // Use the popup editor on the second column TablePopupEditor popupEditor = new TablePopupEditor(); table.getColumnModel().getColumn(1).setCellEditor( popupEditor ); JFrame frame = new JFrame("Popup Editor Test"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add( scrollPane ); frame.pack(); frame.setLocationRelativeTo( null ); frame.setVisible(true); } } </code></pre>
