How Do I...
Parameter connections enable you to provide a parameter value to
another connection. If a connection is shown as a dotted line, it
requires one or more parameters.
There are three types of Parameter connections:
- Parameter-from-attribute
- Parameter-from-attribute connections use the value of an attribute as the
parameter to a connection.
- Parameter-from-script
- Parameter-from-script connections run a script whenever a parameter to a
connection is required. This connection is much the same as a
parameter-from-attribute connection except that the value supplied to the
connection is returned from a Smalltalk script instead of a part attribute
value.
- Parameter-from-action
- Parameter-from-action connections use the result of an action as a
parameter to a connection.
The connection is, by default, a purple line with a large dot at one end
and a hollow dot with a square in it at the other end.
