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.

input, type button JButton
