|
* A view for HTML <code><object></code> tags.
|
|
*
|
|
* This is a {@link ComponentView} that creates special components depending
|
|
* on the object specification. If the object tag has a classid attribute, then
|
|
* this view will try to load the class specified by this attribute using the
|
|
* classloader that loaded the associated document. If the class could be
|
|
* loaded, an instance is created and the type narrowed to {@link Component}.
|
|
*
|
|
* It is also possible to set bean properties on the created component using
|
|
* nested <code><param></code> tags. For example:
|
|
* <pre>
|
|
* <object classid="javax.swing.JLabel">
|
|
* <param name="text" value="sample text">
|
|
* </object>
|

* </pre>
