Hello all,
I'm porting my project from XCode 2.5 to 3.0 and have a big trouble
with custom controls. I have some custom controls (subclassed from
NSControl), that I use in Interface Builder to create GUI. When I
used IB 2.5, I placed Custom View object to the window, changed it's
class and then
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
I have a custom view in a NSPredicateEditorRowTemplate. It seems like
the NSPredicateEditor isn't aware when I change the state of the
custom view, because when I ask it for the predicate it just returns
the old one without even calling predicateWithSubPredicates on my
template. I'm

Funny thing is, although I've used the style he advocates for a very long
time (15 years???), I don't agree with his reasoning.
Indentation of *code* should be consistent, an object comes into scope where
it's declared, not at an opening
If you've already parsed the text, just use NSNumber's class method
+numberWithDouble (or whichever other method is appropriate for your
needs). If you don't want to use your own parser, you can use NSScanner
on your text, but make sure you've set the locale to correctly interpret
the comma.

Hi to all,
I am programming a sort of game purely in Quartz 2D API, but i want to
accelerate the blitting process with Quartz GL, but i can´t find any
information in the developer docs. Anyone with experience in Quartz GL
can help me how to implement this in my code. Thanks in advance.

I have found stuff on the internet about issues with throwing C++
exceptions, and I've run into something which I think is what these
articles are talking about but I'm not 100% sure so I thought I'd ask.
I have some C+ code that is being called as a result of the AppKit
framework updating a view
In the 32 bit [legacy] Mac OS X runtime, C++ and Objective-C
exceptions Do Not Mix. Oil water. C++ exceptions are ignored by
@try/@catch and vice-versa.
In the modern runtime (64 bit Mac OS X elsewhere), the exception
model has been unified. Not only are C++ and Objective-C
Another way to do this is to implement the NSMenu delegate methods:
- menuWillOpen:
- menuDidClose:
You would then set the highlighted variable there. I think it'll make
the code easier to read. You need to set the menu's delegate for this
to work (obviously).

64-bit is the sticking point. If you build for 64-bit, they're

64-bit is the sticking point. If you build for 64-bit, they're unified, but
Apple can't change the 32-bit runtime on the Mac for compatibility reasons.
So the switch would be setting the architecture to 64-bit and removing the
32-bit architecture. But of course then your app won't run on Macs

You'll need to set some sort of flag that prevents any other actions
from happening for the period of time the animation takes.
you an do this using a timer to 'shut off' the flag, or you can use
explicit animations rather than implicit ones and then implement the
delegate method
