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 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 reset	JButton
input, type submit	JButton
input, type text	JTextField
select, size > 1 or multiple attribute defined	JList in a JScrollPane
select, size unspecified or 1	JComboBox
textarea	JTextArea in a JScrollPane
