Yes, sorry, the superview is really the NSClipView.

The problem is that I don't know how.
I am actually trying to update the whole window at any key pressed,
unsuccessfully. I made this in the NSTextView subclass:


- (void)textViewDidChangeTypingAttributes:(NSNotification *)aNotification
{
    // I have tried all the 3 ways here, unsuccessfully.

    [self setNeedsDisplay:YES];
    [[[self window] contentView] setNeedsDisplay:YES];
    [[self window] update];
}


Also, what's IIRC?


Best Regards
