问题描述

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.

推荐答案

您需要将NSTextField子类化.参见 CocoaBuilder线程:

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]];
    }
}
