- All Implemented Interfaces:
ActionListener
,EventListener
,SwingConstants
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 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 |
