Prevent link creation from specific port ? #154

Closed Morphexe closed 4 years ago

Morphexe commented 4 years ago

After digging around the source I cant seem to find a way to do this.

My use case is, I have nodes that can only be connected to (link order matters), so I am trying to find a way to prevent the drag that gets initialized from the port, is there a way to do this that I am missing?

From my experiments, it seems PortWrapper is the way to go about this, but there is no easy way to hook into it sadly.

Essentially for someone wanting to do this, you can hook into onLinkStart action, and just do any kind of validation there instead! I missed this onto my pass through the source code.
