How does one wire up the challenge on 119 ?? (The resize delegate?)

I can't seem to figure out how to set the outlet for this.

Any shoves in the right direction would be useful. Thanks.

Yeah, I never figured this one out either.

It's frustrating because the challenge comes just when you feel like you have a handle on things.

If you want to see what others have done about the challenge you can go here and put in the page number:

But if you want to figure it out on your own...just make sure you've set the outlet to the window and also the delegate, then simply implement the windowWillResize:toSize delegate method.

Thanks ... this might be helpful. (Seriously ... the link may be invaluable!)

Unfortunately I have to fly out tonight to Anaheim. As soon as I return I'll give these a try!

Pointed question: How do you set the outlet to the window? I've added the outlet in the header (.h) file, but where do I drag/drop in IB? I've tried all obvious possibilities.

To set the outlet to the Window, CTRL-drag from your controller object to the window's titlebar. Then highlight the proper outlet and click the Connect button.

Also, in order for your controller object to receive notifications from your window, you have to set your controller object as the window's delegate. Do this by CTRL-dragging from the window's titlebar to your controller object. <-- This piece is what wasted a few hours of my time in a project of my own.

[techtrucker]

PBG4 User is correct...or you could alternatively ctrl-drag from your controller object to the window object in the Instances window. Only difference really is the distance the mouse travels...
So start by ctrl-dragging from your controller object to the window and set the window outlet. Then for the delegate you can drag from the window object to the controller object and connect the delegate, or set the delegate programmatically.

One other thing I forgot in my earlier post; you will need to add the new outlet to the object in IB. Just double-click on the object in IB, then change the dropdown to Connections in the Inspector window. Outlets & Actions will be shown here. Just click the Outlets tab, then click the add button to add the outlet to the object in IB.

Once you've done this, the outlet will be available for connection in IB.

Of course, you can only do this the first time or else you'll overwrite your code. After that you have to manually code your outlets.

(I really wish I could avoid this drag & drop stuff and just code the same thing ... it seems simplier ... but I'm coming from a Windows programming perspective where I very rarely do drag/drop anything ... even when it's available.)

I didn't say to generate the class files, I just said to add the outlet to your object in IB. If you add an action or outlet once you've generated the class files in IB you'll have to manually add them to both your object in IB and your .h file in XCode. You most definitely don't want to regenerate the class files once you've started coding in IB or you'll be playing with the horror that is File Merge.

I just reimport my .h files into IB after I make the change. It has never dropped an existing connection yet.

That's the way that the book recommends doing it. I wasn't even aware that there was another way.

(That's why I love this forum .... learn something new every 10 minutes really.)

I didn't realize you could import .h files into IB! *flies off bridge* I just added the outlet in the .h file in XCode then added to the object in IB. Guess I should get this Hillegass book at some point.

Yep, it's "read class.h" file in the menu, or just drag it from XCode into the IB window.

[techtrucker]

Yeah, I too use the "read bla.h" all the time, in some pretty complicated apps, so far so good. Sometimes I hate having to manually add outlets and actions for new controls in the header, but I've gotten used to it.
Let us know when you get the challenge figured out!

Wow! I never saw that menu item. I just assumed I always had to be in drag!

Is this challenge in the first edition of the book? If I already own the first edition would it be worth it to get a copy of the 2nd edition?

I believe that there are a lot of changes in the 2nd edition. I am not sure what they are. ( I do distinctly remember one chapter where he said "Folks in edition 1 did this differently.) ... but I can't remember which chapter.

Personally I'm hoping for an edition 3 that covers XCode 2.0. <smile> (And maybe Coredata)

[techtrucker]

Yeah, and maybe more on Bindings too, still haven't fully got a handle on them yet...
