Is it possible to place widgets at arbitrary positions inside a canvas? Apparently that can be done in Java, but I haven't come across any examples in seesaw. I tried a paint function like
(fn [c g]
(.add c button '(x y))
and although it didn't produce an error, it also didn't display the button.
I can't find anything about this in the seesaw.graphics api (not surprising perhaps since it's out of date). Could someone give me a pointer?
