I had a bit of trouble tracking down where the ImageStream object is
handled, and I think I've worked it out, but it's quite odd, even for
a demo.
As far as I can tell, an Image is created from the provided file name
and held in a pointer. That image is cast to an imagestream for some
housework. A texture is created and the image is set as it's source -
this is all a pointer, as far as I can tell, not the refPtr I expected
to see.
Then, the main thread seems to forget about the image/s, and moves on.
It then goes into a visitor, which finds any images and makes a ref
pointer list to them. Is that about right? So there's a ref pointer
and a raw pointer floating around at once? And for a while, only a
pointer? Isn't that a pretty nasty situation? Am I missing some C++
kung-fu to make refPtrs in the texture or earlier?
Is there an example with a 'better' management of image/stream objects?
Regards,
Bruce Wheaton
