DESCRIPTION ^

This role may be implemented by a control feature that needs to access a control and do something with it immediately after the control has been completely constructed.

The feature must implement the initialize_control method.

ROLE METHODS ^

initialize_control

This method is called on the feature immediately after the control has been completely constructed. This method is called with no arguments and the return value is ignored.
