Yes, they are. Sorry, I was over selective in my first post in an attempt to
just show the salient points. Here's a more complete excerpt from the code that
sets up the text storage etc:
// Get the string from the File entity
NSError *error = nil;
NSString *str = [[NSString alloc] initWithData:[file
valueForKey:@"content"]
encoding:NSUTF8StringEncoding];
if (error) {
[NSApp presentError:error];
return nil;
}
// Setup undo manager for this file
undoManager = [[NSUndoManager alloc] init];
// Setup a text storage to hold this string
NSMutableAttributedString *attStr =
[[[NSMutableAttributedString alloc] initWithString:str] autorelease];
textStorage = [[NSTextStorage alloc]
initWithAttributedString:attStr];
// Add a main layout manager
NSLayoutManager *layoutManager = [[NSLayoutManager alloc] init];
[layoutManager setAllowsNonContiguousLayout:NO];
[textStorage addLayoutManager:layoutManager];
// Now add the container to the layout manager
NSTextContainer *textContainer = [[NSTextContainer alloc] init];
[layoutManager addTextContainer:textContainer];
// Clean up
[textContainer release];
[layoutManager release];
[str release];
I think that's all ok, but I could be wrong. Again, the main point seems to be
that this works as long as "str" is not empty. If it is, then I get those
exceptions when the first character is typed in the text view.
Thanks again,
Martin
