Well, I was going to argue with you, but your post triggered further
investigation. I realized that in the past, I had constructed my own.
Somehow, in this case, I got it in my head that the bindings would make the
text view use my NSTextStorage. Duh. So I changed to the following in the
test app:
@interface MyDocument : NSDocument
{
IBOutlet NSTextView* tv;
NSAttributedString* ts;
}
@property(copy) NSAttributedString* ts;
- (IBAction)insertSomething:(id)sender;
@end
- (IBAction)insertSomething:(id)sender {
NSUInteger index = [tv selectedRange].location;
NSTextStorage* vtc = [tv textStorage];
[vtc beginEditing];
[vtc insertAttributedString:[[NSAttributedString alloc]
initWithString:@"XYZ"] atIndex:index];
[vtc endEditing];
}
At least now, I'm dinging the right text storage and the insertion works.
However, it does confirm my original problem, i.e., that the programmatic
edit does not show up in the bound NSAttributedString unless there is an
additional text-entry edit. Now I'm thinking bug report, unless there is
something else I can do to trigger the KVO for programmatic edits.
I suppose a workaround could be to set up a dummy ivar and a dependency to
make it update.
