c.
There's no "special" objects or anything. add_child() returns the first
parameter given to it strictly as a convenience so you can code in the
above (quoted) form. So:
img = kaa.canvas.Image("foo.png")
container.add_child(img)
is semantically identical to:
img = container.add_child(kaa.canvas.Image("foo.png"))
Also this works, but I'm not sure if I'm going to keep this API:
img = container.add_image("foo.png")
It's another convenience function but it requires methods to be
explicitly added to kaa.canvas.Container for each object type, so it's
not very elegant. I'll probably end up removing that style of call, so
don't use it. :)
Cheers,
Jason.
