It would be easier to test if each one is in the array controller’s “selectedObjects”. However, I wouldn’t do that either. Given that the selection status of an object affects its appearance, I’d say it’s better to make it an explicit property of each selectable object. Otherwise, you’re forced to drag the array controller’s API into all of your drawing code. As far as I’m concerned, an array controller is a piece of glue code, a necessary evil. Any reference to it in code is at best a disappointment, at worst a design failure. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
