public Class ObjectView

extends ComponentView
Class Inheritance
Imports
java.awt.*, javax.swing.*, javax.swing.text.*, java.beans.*, java.lang.reflect.*, sun.reflect.misc.MethodUtil
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>
