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.
Attribute linking
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.
Drag and drop operations
enabling information to be transferred from one component to another by defining “drag”
attributes on one component and “drop” attributes on
the other.
Event handling
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.
