Hey Clint,
here's some pseudo code. and im currently only posting a notification
when i drag a mouse.....just testing to see if tis would actually
work the way i want it to.
my3DObject class: (poster of notification)
static NSString *NSObjectDidChange;
//called when object is changed to post a notification
-(void)objectDidChange
{
[[NSNotificationCenter defaultCenter]
postNotificationName:NSObjectDidChange object:self];
}
myView classes (each view is observer classes):
- (id)initWithFrame:(NSRect)frameRect
{
.
.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(viewNeedsUpdate:)
name:NSObjectDidChange
object:mySuperModel];
.
.
}
- (void)mouseDragged:(NSEvent *)theEvent
{
// change object accoridingly
.
.
[myObject objectDidChange];
}
i'm not even posting a notification in the mouseUp method. but it
only seems to be refreshing the views when i life the mouse button
(ive commented out all the "[view setNeedsDisplay:YES]" in the code.
Out of curiosity i put a debugging statement in the
"objectDidiChange" method...a "printf"...and it just keep coming into
this method no matter what..weter or not the mouse is pressed or not.
Thanks.

Aaron-
could you be more specific (code snippets) as to where you are
sending notifications.
it sounds like your posting the notification with mouseUp:(NSEvent
*)event
instead you would want mouseDragged:(NSEvent *)event
without code i can't really tell if my suggestion is relevant or at
least not completely stupid, so i could be way off.
