Disable dragging of specific nodes

[SciManJD]

Hi, I would like to disable the dragging of the specific nodes. Actually I would like to decide this at runtime. I mean, when I catch a node, I want to check some conditions and to decide if this node can be dragged. Is this possible somehow? Maybe I can do this somehow with the dropValidator, but it is not clear how.

Hi, I'll have a look, I can't quite remember if a disabled node isn't draggable.

But no the dropValidator is only called when the drop has happened. I am guessing your use case will require a "beforeDragEvent" or equivalent.
