I have some parts which are neither Visual nor Non-visual parts (i.e. they
are just normal Smalltalk classes with a part public interface).

I would like the attribute 'self' to appear in the preferred list - so
'self' will appear in the 'Connect' menu of these parts in the composition
editor.  Does anyone know how I might do this?

Cheers,

Matt,

        MyClass>>preferredConnectionFeatures

                ^#( self )

In 4.0 or higher specialize abtSelfReferenceAttributeFeatureBuilder

        MyClass>>abtSelfReferenceAttributeBuilder

                ^super abtSelfReferenceAttributeFeatureBuilder
                        attributeSettingNamed: #isPreferred put: true.

Best regards,
