Disable NSTextField without changing color of multi-colored text

问题

Whenever I disable an NSTextField the text loses its color and changes to gray. How can I disable the text field and keep the text color? In my particular situation some words are colored red. I'd like those words to stay red when I disable.

You need to subclass NSTextField to do that. See this CocoaBuilder thread:

- (void)setEnabled:(BOOL)flag
{
    [super setEnabled:flag];

    if (!flag) {
        [self setTextColor:[NSColor secondarySelectedControlColor]];
    } else {
        [self setTextColor:[NSColor controlTextColor]];
    }
}

I discovered that while I was editing the text I could set colors and everything, but the problem of the text losing color was happening even when I didn't disable the text box. I had neglected to allow my NSTextField to allow rich text. Now the textfield keeps all colors even when I setEditable:NO.
