* <tr><th>Element type</th><th>Swing component</th></tr>
* <tr><td>input, button</td><td>JButton</td></tr>
* <tr><td>input, checkbox</td><td>JButton</td></tr>
* <tr><td>input, image</td><td>JButton</td></tr>

* <tr><td>input, reset</td><td>JButton</td></tr>
* <tr><td>input, submit</td><td>JButton</td></tr>
* <tr><td>input, text</td><td>JButton</td></tr>
* <tr><td>select, size > 1 or with multiple attribute</td>
* <td>JList in JScrollPane</td></tr>
* <tr><td>select, size unspecified or == 1</td><td>JComboBox</td></tr>
* <tr><td>textarea, text</td><td>JTextArea in JScrollPane</td></tr>
* <tr><td>input, file</td><td>JTextField</td></tr>
