When connecting objects using links, we refer to the objects as SOURCE and TARGET objects.
A regular link connects a SOURCE directly to a TARGET.
A passthrough link connects a SOURCE to a TARGET through intermediate frames rather than directly. This allows objects contained in different Frame objects to be connected.
In the diagram above, Frame1 contains both Object1 and Frame2. When Object1 connects to Frame2 through a DATA link, and Frame2 connects to Object2, a passthrough link is automatically created between Object1 and Object2. This occurs because Frame2 acts as both a TARGET for Object1 and a SOURCE for Object2.
You can find an example of a simple passthrough link in the sample screen "SamplePassThroughLinkScreen". This screen also demonstrates a multilevel nested Frame example with connections through two levels of Frame nesting.
Currently, DATA is the only supported link type for passthrough links.
