Hi Greg,
I mistakenly posted to this list first, when I should have posted to
the sdk list.

Constraints are immutable objects, once you create them, you cannot
change them. This is a limitation of the constraint layout manager. If
you need more fine-grain control, use a custom layout manager.

I derived the constants by performing the calculation, and printing

oooh, damn... I was afraid someone was going to say that. I just hoped
there might be some way to force a float to conform to what NSLog %f
prints... That seems like it might be a useful function - something
like pround(aFloat), for "print-round", to force any float number to
round as the p
If what you really want is to see whether the result is the same as %f
previously printed, then you could always make your array of constants
an array of constant _strings_ and then compare the strings. Not
terribly efficient, maybe, but straightforward.

Now, when I run the calculation "live" and try to compare to my

because the result of the calculation *isn't* actually what I

NSLog. So,
I'm not seeing exactly how to go about running my screen save on both
of my displays.
At least I'm not seeing an accessor that allows me to add the rendered
screen saver to more than one display. How would I go about doing that?
Thanks

ScreenSaverEngine will always create one instance of your saver view
class per screen.

hmm... Well, this all sounds like a sledge-hammer approach to my
immediate problem.
The actual explanation of what I'm doing is kind of long-winded, so
I'll spare you that. For now, I know the calculated values will always

One thing I love about this list; I *always* get useful info.
I'll find a better way to do this soon. In this particular case, the
"match" could be specified as broadly as any value falling within a
sort of "bin." The "bottoms" of each of these

Sigh. Hit shift-cmd-D a bit too soon. :)
It does not seem I can invoke this on the main thread.

Cocoa has always been lacking in the RegEx department (at least the
'built-in' Cocoa classes, there's a bunch of third-party regex
frameworks), especially when compared to languages like Python. Since
your situation isn't very complex, I would just use the bread-n-butter
string APIs:

That did it, adding
[[ self openGLContext ] flushBuffer ];
To the end of getFrameForTime: did the trick.
