The autosizing mask doesn't seem to help. To clarify the problem, the device is
in landscape mode, the title bar is shown in landscape. The view is not drawing
from left to right (480 pixels across), but rather from top to bottom (480
pixels down causing the rendering to go off screen). It's as
Ian,
Are you saying that the view is drawing in the proper orientation but it isn't
filling the width of the landscape display? If this is the case, I would have
a look at the autoresizing mask settings for the problematic view(s).

I need to draw a cross-hair on top of a QTCaptureView with a video preview from
a USB camera.
For this app, I am starting from the sample project QTRecorder.
I create the cross-hair line in the Interface Builder.
Problem is that the video is always on top, overwriting the cross-hair lines.

In my braille app, the font "Apple Braille" looks kind of wimpy when
printed. Some people say it's hard to read. I thought I'd try making it
bold, but for some reason, Apple Braille does not go bold in any app I've
tried.
Okay, so maybe there isn't a bold variant of the braille font installed. So

No - you haven't allocated/inited the paragraphStyle object, nor initialised
the variable. Most probably this will crash. Also, there's

Load your data into memory, create an NSBitmapImageRep from that pile of

Hi all,
If it is true that the ONLY safe thing you can do in dealloc is release
instance variables, then where else/how else are you supposed to implement a
method that is guaranteed to be called upon an object's termination, so that
you can do final cleanups, such as removing it as an observer

Thanks, there is no immediate need to override so I will try calling it.
So would this work?…
CGFloat spacing = 5.0f;
NSMutablePargagraphStyle *paragraphStyle;

I remember reading that the only safe thing to do in your dealloc method is to
release instance variables. If you look at lines #23 - #25 in the call stack
below, it appears that NSDocument's -dealloc is doing more, sending
-removeAllActions to its undo manager. Similarly, lines #7 and #8 say

I want to present the menu after a dt has passed with the mouse pressed, so the
