LightTable Sample CoreAnimation Code

Hello all, I've been attempting to make sense of Apple's "LightTable" sample code for Core Animation, and I'm completely lost. Specifically, a couple of calls appear to be assigning an NSImage to the contents of a CALayer, which, as I previously understood, (and according to the documentation)

NSTextField: Change Text Color at Insertion Point?

Hello Cocoa-devs, I've a got an out-of-the box NSTextField that I'm trying to apply various string attributes to, including colors. I'm not using the standard color panel, since the application I'm writing can only support a very limited set of colors, so I just have a menu with a list of color

Tutorial for writing a bindings-compliant NSView subclass?

Hello fellow Cocoa-devs, Does anyone know where to find a good tutorial or more information about writing a bindings-compatible subclass of NSView? I've seen Apple's example code on the subject, but it looks like it's a lot more complicated than it should be. I don't need Interface Builder supp

You could try calling NSWindow's setBorderThickness:forEdge: on NSMaxYEdge. Don't know if it will work, but that would be where I would start. HTH, Alex On Jan 3, 2010, at 11:41 AM, PCWiz wrote: I have a window that looks like this right now: http://img22.imageshack.us/img22/2953/screensho

I'm sorry, I misread; you're talking about NSColorPanel. You might try sending setContinous:NO to the color panel. Hope that helps, Alex Heinz On May 26, 2009, at 8:54 PM, Alexander Heinz wrote: NSColorWell is a subclass of NSControl. It should respond to setTarget:. Just use t
