custom NSView drawing not working

Question

I'm trying to write a custom NSView that supports adding a background colour. I override drawRect

- (void)drawRect:(NSRect)rect {

    [[NSColor blackColor] set];  
    //[NSBezierPath fillRect:rect]; //I tried this too  
    NSRectFill([self bounds]);

}

And I set my custom view type to replace the content view NSView of my main window. But when I run it, the background does not turn black as expected - but some contained subviews do.

What I am doing wrong? My draw method is definitely getting called, but background does not change.

Do not replace the content view of your window as it is treated specially. Add your custom view to the content view, and set the autoresize flags instead.
