void FlowCanvas::Item::set_partner | ( | boost::shared_ptr< Item > | partner | ) | [inline] |
Set the partner of this node.
Partner nodes are nodes that should be visually aligned to correspond to each other, even if they are not necessarily connected (e.g. for separate modules representing the inputs and outputs of a single interface). The partner is invisibly connected as if it had an input that is connected to this item, e.g. foo.set_partner(bar) will arrange like: [foo] [bar] with a left-to-right flow direction.
