| * 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> |
