Hi list,
I'm playing around with layers and there are some subtleties I don't
quite get when using layer backed views. I did some animations using
"pure" CALayers as a proof of concept for a view. Along the way I
figured I'd like to have subviews (NSViews) embedded in it and so I
went back to do everything using NSViews that have setWantsLayer set
to yes.
I noticed that if I change the zPosition of the view's layer it does
not animate while it used to when using CALayers only. The position
changes correctly, I'm only missing the animation. Changing the view's
frame using the animator works fine. I'm wondering, is it safe to
change attributes of the layer when the view is in layer backed mode?
If it is not safe, is there a way to change transform of the view ?
Thanks.
