Namaste! Thank you for the replies. I originally attempted to get this going through an array controller but failed, so I figured it couldn't be done that way and went to a routine to do it. However, your previous reply sparked something and I got the array controller partially working. It now

RE: Creating an ordered list for combo-box content from a Core Data entity attribute

Namaste! I answered my own question: @"" This sorts properly. Now, for a follow-on, is there anything wrong with using that and binding the content/content values in the combo box to solely "arrangedObjects" ? Thanks!!! Peace, Love, and Light, /s/ Jon C. Munson II > -Original Message---

RE: Creating an ordered list for combo-box content from a Core Data entity attribute

Namaste! OK, for the sake of the discussion: 1. I have an entity called Item. 2. Item has many attributes, the one of interest is Color. It is a string attribute. 3. Assume acItem, an array controller is bound to Item. 4. Assume acItemColors is bound to Item (but not editable), and has the

Re: how to load an NSMenu out of a nib?

Making a class with an outlet, and passing an instance of that class as the nib's owner, is one way. You can also use the NSNibTopLevelObjects key as described at the bottom of http://developer.apple.com/DOCUMENTATION/Cocoa/Reference/ApplicationKit/Classes/NSNib_Class/Reference/Reference.html

Transparent NSButtonCell highlight

Hi, I'm building a transparent interface, and I'm stuck at NSButtonCell. An NSGradient with transparency is drawn in the cell. It overrides - isOpaque to return NO. The gradient is drawn nicely from drawWithFrame:, but if it's called from -highlight:withFrame:inView:, the gradient is drawn
