Where can I find a discussion of what Tags are, and how to use
them? TIA
I'll assume that you're referring to tags in the context of
cells and controls in Cocoa ;-)
A tag is an integer value that you can assign to a cell such as
a menu item, or a text cell. You can set tag values
programmatically, or using the interface builder inspector.
I tend to use tags on popup menu items, so that when I want to
know what option a user has picked, I can send the -tag message
instead of trying to figure it out from the position of the menu
item (which might change), or even worse, the title of the menu
item (which *will* change when the app is localized).
