I want to be able to drag text from a ListIconGadget and drop it into an EditorGadget at the point where the cursor was before I moved it from the EditorGadget to the ListIconGadget.

How do I do that? I can't even seem to get the line number I was editing never mind the cursor position within that line

Thanks.

Thanks KCC (and Danilo)

Unfortunately I think that's only going to work on Windows and I'd really like a way that will work on Linux too.
