Grrr, seems like I should know this, or at least be able to find out, but so far, no good.

What is the trick to triggering the controlTextDidChange: delegate method/notification when you set the text of a NSTextField (for instance) *programmatically*?

You can just do this manually, like this: (warning - written in Mail, untested, use at your own risk, and all that)


[someTextField setStringValue:@"Hello world"];
[[NSNotificationCenter defaultCenter] postNotificationName:NSControlTextDidChangeNotification object:someTextField userInfo:[NSDictionary dictionaryWithObject: [[someTextField window] fieldEditor:YES forObject:someTextField] forKey:@"NSFieldEditor"]];

Thanks; I had figured I could do this, and was actually in the process of writing this when you replied. I was thinking Cocoa had a more "elegant" manner to do this, rather than having to do it manually, but it works, so I'm happy.
