The typical idiom is to try to dequeue a reusable cell. If that returns nil,
create a new cell. No matter whether it was dequeued or created, configure the
cell (i.e., assign values to labels, configure decorations, etc.). Dequeuing
saves you the overhead of creating new views but you still need

Hi,
For my iPad app, I'm using a UIViewController subclass called
SidebarViewController to display some stuff in a sidebar. In the sidebar I have
a calendar control. I'm using the open source Kal component from
http://github.com/klazuka/Kal. In the -viewDidLoad method of
SidebarViewController,
When initializing an NSPersistentDocument with sqlite store in a Mac app, I
insert what I call a "singleton" managed object, like the "Department" in
DepartmentAndEmployees. It's simply a container which has a to-many
relationship to its containees (i.e., employees). Delete Rule is Nullify.

It isn't the width that I'm so much worried about, rather, it's the
height. You can see how the white fill runs up into the gray that is

Thanks. I wasn't aware of child windows. Can they be made document-modal?

Try changing that.

I don't think toolbars on sheets are supported. As you said yourself,
the user might get confused if there a two toolbars in a single window.
I haven't found anything specific in the HIG about this, so I'd be interested
in some opinions...
I have an modal editor sheet that attaches to a document window to allow
certain document contents to be manipulated. The sheet is somewhat complex, and
toolbar items are definitely helpful to have

heh... yeah, that's true. But the thing is I haven't done anything different

Hello,
I need to simulate a mouse movement defined in physical/logical units rather
than pixels, in OS X 10.6.
Is it possible to do that?
Thank you!

Yeah, using "Real Mem" in Activity Monitor is
Hi,
Thanks for the reply.
I used matrix to display data inside a sector years ago, when I had just
started learning cocoa.
I know its a crude and inefficient way to make a hex viewer, but currently its
not required to be sophisticated at all and I didn't have the time to make any
big changes.

This is a really terrible way to make a hex viewer. Consider using NSTextView
or just use a custom view (I think I've seen a 3rd party open source

I have three matrices (all same sub class of NSMatrix, having prototype as a

instead of complex custom views for display.
