RESOLVED: Drag and drop callback system

does it not define ‘dragitems’ ?
I have repleced it with ‘info’ will be good.

Btw, its TouchDesigner 2020.46540

Info is usually a dict, so try info[„dragItems“]

Ah, yeah that was a bad callbacks version in experimental. Fixed in new official, but Achim is correct. You can just put dragItems = info['dragItems'] at the top of your callback and everything should work.
