Sorting a NSTableView:
See pg 132-134 on how to select (or implement) a comparison method

UNDO!:
iThermostat.app is an example
*NOTE: Undo / REdo stack is, by default, grouped per action. If hitting a
button puts 15 things on the undo stack, those 15 undo actions are called
when hitting undo.
TEXTVIEWS!:
Undo is automatic iff you set undo allowed in the attributes inspector
Hillegass p. 150
NSArrayController:
TURN OFF the Preserves selection!!!!!!!!!!!!!!! box
NSCoder (read/write obj to disk)
**The advanced book has DO (Distributed Objects) !!**
See Chapter 8 for simple serialized-to-disk doc files.
Multiple Nibs:
**See the extra chapters in the handout book on view swapping**
Make things that won't necessarily appear on the screen not load until
they're needed.
Good for things like preferences
User Defaults (NSUserDefaults):
There is a controller for this = sharedDefaultsController
CoreData:
weeeee!
See the app with coredata on it

--------------------------------------------------------------------------------------------

Custom Views (OvalView.app, Hillegass chp. 14):
in IB
Subclass NSView
Make Files
Drag Custom View (say, OvalView)
Make Custom Class of Custom View in inspector point to OvalView
NSView Methods covered
drawRect (within custom view boundaries)
mouseDown (event within the window's boundaries)
mouseDragged (event within the window's boundaries)
Add printing (Quartz 2D)
Just connect the print menu to the custom view's print action
IB Tricks:
Option-Drag most anything in IB and you make a matrix of (say) buttons
Layout:
Make subview of... lets you make something an inner view
of something else
(Aside)
Quartz Debug (performance tool)
Tools:
Show user interface resolution (change to say 1.5)
Allows you to check your application for resolution independence
(end Aside)
NSRect:
Origin: NSPoint
NSRect: width, height
NSBezierPath:
Draws lines, rectangles, curves (<--the usual Bezier)
Toys:
TO change Scale of an image (There are other toys in a file on the Dav server):

- (IBAction)changeScale:(id)sender

{

	float scale = (float)[[sended selectedItem] tag] / 100.0;

	NSLog(@"new scale = %f", scale);

	NSClipView *cv = [[stretchView enclosinScrollView] contentView];

	NSSize unscaledSize = [cv frame].size;

	NSSize scaledSize;

	scaledSize.height = unscaledSize.height / scale;

	scaledSize.width = unscaledSize.width / scale;

	[cv setboundsSize:scaledSize]

}

NSImage
holds imageReps of various kinds (image representations)

Notification Centers:
NSNotification center as per usual
Post to the center
Observe an object
Observer is notified when my object posts
Observers are not retained by the notification center
- SO! we have to remove an object from any Notifying objs for which
it is registered on in it's own dealloc method.
- in Objc 2.0, garbage collector automatically removes me from objc
on collection
Delegates are automatically registered

Localization:
Ick - It's hard

Keyboard Events
(AM will like this)
Chp 16 - Catch the keyboard input

BigBang Chess from freeverse - Check it out. The guy who wrote it is
doing an OpenGL bootcamp in (november?)
