Grayed out buttons. Best approach?

[milktooth]

How do you gray-out buttons, particularly segmented controls?

I've tried setting alpha to .5, but with segmented controls the left and right parts overlap leaving an opaque strip in the center. Is there a preferred approach?

The best I've come up with is putting a half-transparent quad on top with the same colour/texture as the background on which the controls appear. It's fiddly though, so I'd say recommended only if someone doesn't have a better idea...

button.enabled = NO;

is the usual way. Not sure for segmented controls though.

Have you tried using setEnabled:forSegmentAtIndex: ?

I have now.

Thanks. Just the ticket.
