When you
create components using the SAS Component Object Model (SCOM) framework,
you can take advantage of four distinct processes that enable components
to communicate with each other.
enabling a component
to change one of its attributes when the value of another attribute
is changed.
enabling a viewer (typically
a control) to communicate with a model, based on a set of common methods
that are defined in an interface.
enabling information
to be transferred from one component to another by defining “drag”
attributes on one component and “drop” attributes on
the other.
enabling a component
to send an event that another component can respond to by using an
associated event handler.
This section describes
how you can add these communication processes to your components.
