- All Implemented Interfaces:
- SwingConstants
public class ObjectView - extends ComponentView
Component decorator that implements the view interface
for <object> elements.
This view will try to load the class specified by the
classid attribute. If possible, the Classloader
used to load the associated Document is used.
This would typically be the same as the ClassLoader
used to load the EditorKit. If the document's
ClassLoader is null, Class.forName is used.
If the class can successfully be loaded, an attempt will
be made to create an instance of it by calling
Class.newInstance . An attempt will be made
to narrow the instance to type java.awt.Component
to display the object.
This view can also manage a set of parameters with limitations.
The parameters to the <object> element are expected to
be present on the associated elements attribute set as simple
strings. Each bean property will be queried as a key on
the AttributeSet, with the expectation that a non-null value
(of type String) will be present if there was a parameter
specification for the property. Reflection is used to
set the parameter. Currently, this is limited to a very
simple single parameter of type String.
A simple example HTML invocation is:
<object classid="javax.swing.JLabel">
<param name="text" value="sample text">
</object>
