The Descendant component contains a property that allows selecting an ancestor component from a predefined list of templates. The component is created after selection of an appropriate template name (or component name) from the list of the templates fitting the specified interface. Any previously used ancestor component is discarded.
Processor Expert allows you to select from ancestors that implement the required interface and are registered by the descendant component.
The ancestor component is displayed under its descendant in the project structure tree in the Components view.
An ancestor component requires a list of methods and events ( interface ), which must be implemented by an ancestor component. The error is shown if the ancestor component does not implement any of them. For example, if the settings of the descendant component do not allow it to generate this method.
