Hi again,
Does anyone happen to know how one could set the opacity of an
NSImageView object? I am looking for a way to simply fade in an image
on within my app's window-- but neither of the NSImageView nor
IKImageView list anything about opacity...
Thank you.

NSView and subclasses have a setAlphaValue: that might do what you
want. It requires a backing Core Animation layer (CALayer) and
therefore is Leopard only. You can have IB setup the layer backing by
setting the view's Wants Core Animation Layer under Effects of the
Inspector window; I
Hi. I've tryed this code and it works. The problem is that with some
machines it causes a kernel panic. They are PPC machines. Isn't this
code compatible?

Hi,
How far back is this compatible? is it only 10.5?

In which case I believe you do want to actually release the window,
and store those factors somewhere in the control layer of your
application. So, when you reopen the window, you can reset those
factors appropriately.

Hi,
I am implementing something like a coverflow. So I have many visual elements
in the background and one which is closer to the user and in focus.
I put a transparent layer on top of the background elements, which makes
them darker. This is very good to make the user focus more on the element

Hi Julius,
Not sure how much help I'll be, but I looked at the screencast and

It almost looks like what happens when you blur a finite, fully opaque
image. The blur filter includes the background, naturally, but

It depends. Does the code take a real C string (char array), or does
