Node callback for handling link insertion and swapping of occupied inputs. Nodes have a feature for moving existing links to unoccupied sockets when connecting to an already used input. This is based on the standard legacy socket types (value/float, vector, color/rgba) and works reasonably well for shader, compositor and texture nodes. For new pynode systems, however, the hardcoded nature of that feature has major drawbacks: * It does not take different type systems into account, leading to meaningless connections when sockets are swapped and making the feature useless or outright debilitating. * Advanced socket behaviors would be possible with a registerable callback, e.g. creating extensible input lists that move existing connections down to make room for a new link. Now any handling of new links is done via the 'insert_links' callback, which can also be registered through the RNA API. For the legacy shader/compo/tex nodes the behavior is the same, using a C callback. Note on the 'use_swap' flag: this has been removed because it was meaningless anyway: It was disabled only for the insert-node-on-link feature, which works only for completely unconnected nodes anyway, so there would be nothing to swap in the first place. |
