Class FormView


public class FormView
extends ComponentView
implements ActionListener

Component decorator that implements the view interface for form elements, <input>, <textarea>, and <select>. The model for the component is stored as an attribute of the the element (using StyleConstants.ModelAttribute), and is used to build the component of the view. The type of the model is assumed to of the type that would be set by HTMLDocument.HTMLReader.FormAction. If there are multiple views mapped over the document, they will share the embedded component models.

The components produced get their opaque property set to false. The following table shows what components get built by this view.
Element Type Component built
input, type button JButton
input, type checkbox JCheckBox
input, type image JButton
input, type password JPasswordField
input, type radio JRadioButton

input, type text JTextField
select, size > 1 or multiple attribute defined JList in a JScrollPane
