Ian:
The same theory applies. I adapted that exact example for my own
purposes. It was a bit of a learning experience, but then again you
get nowhere by having code handed to you. ;-) Just take a look at the
docs (the text system overview, I think) and see how an NSTextView is
constructed. That'll clue you in on what to adapt in the example you
were pointed to.

Thanks Ryan,
Unfortunately, my original subject line was wrong and misleading. I
meant to say NSTextView (as it is now), not NSTextField. So I
tried out your link, but it wasn't what I was looking for. Any
other clues?
Ian.

Hi,
I've been looking around for a solution to this problem, and
there certainly seem to be people who can make this work, but
after gathering together everything I understand about the text
architecture, it just doesn't work. So with an NSView in a
window, this was my attempt to make the simplest possible
application to figure it out.
- (void)drawRect:(NSRect)rect
{
[self setAutoresizesSubviews:YES];
textStorage = [[NSTextStorage alloc] init];
NSLayoutManager *layoutManager;
layoutManager = [[NSLayoutManager alloc] init];
[textStorage addLayoutManager:layoutManager];
[layoutManager release];
NSRect cFrame = [[[self window] contentView] frame];
NSTextContainer *container;
container = [[NSTextContainer alloc]
initWithContainerSize:cFrame.size];
[container setWidthTracksTextView:NO];
[layoutManager addTextContainer:container];
[container release];
NSRect tvRect;
tvRect.origin.x = 150;
tvRect.origin.y = 150;
tvRect.size.width = 100;
tvRect.size.height = 100;
NSTextView *theTextView = [[NSTextView alloc]
initWithFrame:tvRect textContainer:container];
[theTextView setPostsFrameChangedNotifications:YES];
[theTextView setHorizontallyResizable:YES];
[theTextView setAutoresizingMask:NSViewNotSizable];
[self addSubview:theTextView];
[theTextView release];
}
So this should be a fairly standard implementation of
NSTextStorage, NSLayoutManager, etc. What I hope to happen is
that as I type in the NSTextView the rect initially described by
tvRect should grow and display text. But what actually happens is
that the text continues on, but doesn't display till it gets to
the edge of the container rect, when it starts on the next line
of the NSTextView. I think there are only a few superfluous lines
(e.g. setAutoresizesSubviews) but I really want to know what the
key thing is that I'm missing. Thank you.
