Hi Seth,
I have a subclass of NSColorWell that broadcasts a
ColorWellDidBecomeActive notification on activate:.
Objects using the color panel listen for the notification and set some
internal flag so that they can either ignore the changeColor message
or not depending on which color well

Hi Tom,
Setting the view controller as the nib's 'file's owner' won't create
the problem. The problem described in the documentation occurs when
you have set up bindings between objects in that nib file and the
'file's owner' (your view controller).
If you have done this, it could,
Hi Tom,
The design from the posts is identical to the one I use for the non-
NSViewController based view controllers that I have to use (for the
same reason as you) - so it can still work for you :) The concepts are
the same. You just have to deal with the extra issues that you're
?
Also, in your snippet, where does anIndex come from?

I haven't yet come across a situation in which it would be desirable
for an NSTableView and its associated NSArrayController to be in
separate nibs. I guess Apple haven't, either ;)
Actually, I would think that it's quite common in apps that use
NSViewController. Imagine a view managed by

Hi Wayne,
One way you could do this is to connect the control to the First
Responder object in Interface Builder, instead of to the File's
Owner. This means that when the action is triggered, it will go to
the window's first responder (probably the view at that point), and
then move
NSArrayController isn't an NSResponder, so you can't add your
subclasses to the responder chain. I think the problem is that you
should be using NSWindowController and NSViewControllers to handle
menu actions, not NSArrayController. Those objects can be added to
the responder chain so
Hi,
I'm hoping that one of the Cocoa engineers out there can answer a
question about NSViewController for me.
In the documentation, it states that the view controller will handle
memory management for the objects in its nib file. Does this only
apply to nib files that are loaded by
Does your window know about the window controller and vice-versa?
It's not clear how you're setting this up from your post, but you
might need to tell the window about your window controller subclass:
[window setWindowController:windowController];
Or the other way around?
Hi Nick,
When you return your item to the table column, I believe this is
setting the cell's object value to this item. The object value of an
NSCell needs to conform to the NSCopyingProtocol.
If you implement the method:
- (id)copyWithZone:(NSZone *)zone
in HDIR to return a copy of the
Hi Peter,
NSScroller has the following methods that might help:
- (void)trackKnob:(NSEvent *)theEvent
- (void)trackScrollButtons:(NSEvent *)theEvent
I've never subclassed NSScroller, so can't comment on the havoc that
may ensue if you go down this path.
NSClipView also receives a
Hi Hendrik,
It seems that you're using the correct mask. The documentation
states that NSViewMinYMargin would make the bottom margin flexible,
which is what you want.
I notice that you originally set the frame for the subview at (0,
0). Is this because the subview is originally the

Hi,
Have you tried using the FirstResponder for this?
Add an action to the preferences window's nib's FirstResponder
called setWindowBackgroundColor. Then connect the color well to
the first responder and connect to that action.

Seriously?
You aren't going to be able to distort your bitmap like this with
NSImage and there is no ready-made CIFilter to do this distortion
that I'm aware of. If I'm wrong about that, then that's the way to
go. But, I think you've gotta do your own pixel pushing for this one.

Noone's going to answer your question. A general rule of thumb to
follow (at least until CocoaTouch SDK is out of beta) - don't ask
about any classes whose names don't start with the letters NS or
CA on this list. I'm sure that there are exceptions - maybe QT,
but generally this list is
Yeah, this is something I ran into dealing with the fact that I have
several key value observations set up. The way I deal with it is to
give my view controller's abstract superclass a -(void)
removeObservations method. I set it up to work similarly to how you
use the -(void)dealloc
If you need to support 10.4, you've gotta do it yourself the way you
described. You don't have to use an OpenGLView, but the animation
will suffer if you use Quartz for drawing. It won't have that really
snappy, responsive feel that I'm guessing you want. OpenGl's going
to give you
in a certain way, but it would be
easier for us to help each other if we were using the same architecture.
Still, pretty interesting :)

I just wanted to say one more thing. I was re-reading what you had

for that first split view.
The problem isn't just the set up of your view controllers and the
order of creating/adding views, you're also
Yeah, the document. The window controller and document have a
relationship, but this isn't true for the view controllers and the
document. Again, this is part of NSViewController's ambiguous role
in this whole architecture. I don't really know how this *should* be
dealt with.
