Visibility of Cocoa objects

[Eric VERGNAUD]

Hi there,

I'm just switching to cocoa, so maybe I'm missing something easy there.

I'm looking for a way to show/hide a NSControl or a NSView. I've ran into
the setTransparent method of NSCell, but it does not remove the view from
the hierarchy, it's still there and active.

What I'm looking for is the equivalent of SetControlVisibility and
HIViewSetVisible.

Hope I'm just blind.

Thanks

Eric

You have two choices. (1) Wait for Panther. (2) Rip the control right
out of the window with removeFromSuperview. Remember to retain it first
or you'll lose it. m.

Thanks. So I'm not blind. But now I wonder why this wasn't implemented in
Cocoa from the beginning...

What's the Panther way?

You know I can't tell you that. m.

Whatever, dude. I don't see how giving me a method name would break the NDA but
telling me that the method exists wouldn't. OTOH, it's not worth my time to
argue with you about this, I can find plenty of people who can just tell me the
answer.
