Tear-Off Attribute
Select Tear-Off Attribute to work with an attribute as if it were a standalone part. The tear-off attribute is not actually a separate part. It is a variable representing the attribute.
When you select Tear-Off Attribute, VA Smalltalk displays the list of attributes for the part you are tearing from. After you select an attribute from the list, you can drop the tear-off attribute on the free-form surface. VA Smalltalk creates a connection (represented by a blue double-headed arrow) between the original part and the tear-off attribute. You can then form other connections to or from the tear-off attribute.
Tearing off is useful when attributes are nested. It allows direct access to an attribute nested inside another attribute. It also allows direct access to an attribute's events and actions.
