Interface IMetaclassSelector

public interface IMetaclassSelector

IMetaclassSelector is a reusable component wrapping an SWT Text widget that can be used to select a single metaclass.
The proposal menu is popped whenever one of the following conditions is fulfilled:

• the user enters any upper case letter character (as metaclass names always starts with a Capital letter)
• the user enters CTRL+SPACE which is the standard completion activation sequence

The metaclasses proposed for completion are those defined in the metamodel filtered by setMetaclassFilter(Predicate) if such a filter is set.

Note: the getControl() method is available to reach the inner Text field, typically for layout purposes.
