Re: How does an instance variable in the ObjC code get connected to an interface element in the NIB file? BACK ON TRACK
Well, Erik, you know that sometimes we inherit working code without knowing much about its history. I don't want to break something that already works (and ships), and re-factoring the whole codebase is not part of my charter. I am trying to add my stuff without disturbing the working app. I think I will be moving a lot of the outlets that concern my module, but as for the rest ... If it ain't broke, don't fix it. (The message thread you mention looks like a rich source. I will have to read the whole thing. I have only been on the forum a couple of weeks, and I am running to catch up.)

Over 130 outlets! Holy Sassafras Tea! That is ten to fifteen times more outlets than I have ever seen in a single class in 20 years of Objective-C programming! I suspect you are doing something very wrong. First, use the Model-View-Controller pattern. Dont store application state or Model data in the View. Second, use patterns like data source and objects like NSTableView and NSMatrix and NSColectionView to structure user interfaces that require lots of objects. Regarding the original question: How does an instance variable in the ObjC code get connected to an interface element in the NIB file? I was hoping someone would point out the answer that was provided in this forum one month before this question was asked (again): http://www.cocoabuilder.com/archive/message/cocoa/2008/5/15/206771 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Okay, I see them now. I was missing them in the rather long list of outlets (over 130!) for the main controller. I wanted to understand this better because I want to re-factor the code so that there are NOT 135 outlets for one controller. Currently we have two windows that handle different tasks, but share the controller. I want separate controllers for each window/task. Thanks, Ken.

I see the connections for the buttons on the interface, and I hit the breakpoints I expect, but I don't see any connections between the member variables and the popup items. It happens when the nib is loaded. As the objects in the nib get created, their instance variables are set up to point to each other as described in the nib. This even applies to your controller object (the one that "owns" the nib), which exists before the nib is loaded — AppKit uses Obj-C introspection to look up its instance variables dynamically and change them to point to the objects from the nib. —Jens smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
