Note that I have asked this question before but I got no answer. So I am asking again to try to get a clear answer.
What data do I need to pass into GeUserArea::HandleMouseDrag so that I can allow dragging and dropping my own gradients onto a Gradient?
I have a list of GradientKnots. I want to allow dragging and dropping of this data into a Gradient.
What should the DRAGTYPE be? And what should the data be?
