As a first note, OpenedImageIndex and OpenedImageKey don’t exist on WindowsForms. I understood the documentation so no issue here.
Anyway, according to the referred documentation I should be able to set those values but I get a SystemReferenceNullException when I try do set it.
See attachements.
Hi Tiago,
This is fixed in the current update. The node editor now is able to show the image thumbnails as well.
Thanks,
Luca
