Extensibility

The following topic relate to extensibility in XWT. There are two types of extensibility: Support of new kind of user-defined UI element and Support register IMetaclass factory via API or EP.

• User-defined UI element: The user-defined UI element can be used directly in XWT when the customer respects the SWT standard signature with two arguments: Composite/Widget parent and Style.
• IMetaclass factory: The IMetaclass factory is used to create some special IMetaclass, which takes care of the UI creation.

Please see the example below to show you the User-defined UI element. The customized UI "UserControl" contains a Button with a selection event.

Now integrate the above example into a new XWT component directly. See the screenshot below.
