For a bit of background, I've got a window, and I'll be swapping its
content view's subview between some other views. One (and more in the
future) of the other views has a subview with "wants layer" set so it
can use some CALayer stuff for fading and such. Now, when I switch
between views for the window, I want the window to resize, and a nice
animated transition (like a cube).
For resizing, the logical method is -[NSWindow
setFrame:display:animate:]. This all works fine... until a descendant
subview has a layer. Then I get a pause, and the window resizes
without animating. If I remove the layer from the subview, the
animation works. (The subview is a descendant of the view which I am
*removing* from the window *before* changing the size. Why does it
make a difference anyway?)
For the animated transition, it appears that IB has a setting for some
predefined transitions. I set the window's "subviews" transition to
Rotating Cube... and yet, I don't get a rotating cube effect when
removing a subview and adding another. If I use the content view's
animator ([[window contentView] animator]) to add the subview, nothing
seems to change... If I do the same, only addSubview:[newView
animator] as well, it seems to try, but it doesn't work all that well.
Can anyone give me some advice here? What am I doing that's ruining
the NSWindow resize animation? How can I get the view transitions
working? Thanks in advance.
