Container SmartLink
The Container SmartLink’s Source object can create and destroy its Target objects. During creation, the Source can tell its Targets to set their positions relative to the Source (provided that the Targets have visualizations).
The Source can also tell its Targets to parent themselves to the Source. If the Source is hidden, viewed, or deleted, then all of its Targets are also hidden, viewed, or deleted (this is standard Progress behavior.)
To maintain a Container SmartLink, the ADM requires the Source and Target objects to SUBSCRIBE to and implement the events shown in Table 3–2. Specifically:
- The Container–Target SUBSCRIBEs to the source events in the Container–Source procedure handle, and must implement the corresponding internal procedure names.
- The Container–Source SUBSCRIBEs to target events in the Container–Target procedure handle, and must implement the corresponding internal procedures.
A Container SmartLink typically connects the following types of SmartObjects:
