Right, that indeed is precisely the solution I ended up using for JACTVocab
2.0. My implementation is very similar to what the OP described: I'm
covering my window with a "glass" child window where I can use layers, and
calling setContent on a layer with an animated transition. (The app gives
the user a choice of transitions, and one of them is a push transition.) I
discussed my thinking in an earlier thread here as I was developing the
animation.
At the time, Uli Kusterer suggested it might have been better to swap views
and animate *that*. And I might still rewrite it that way. m.
