I'm porting an app from Carbon to Cocoa. I notice that when I use the
carbon function PickColor to get a color dialog, the dialog has OK and

those buttons. Is there a way to get OK and Cancel buttons in the
Cocoa version of my code?
NSColorPanel is very much a self-contained class that offers little
customisation in itself (though you can add custom pickers to it). Its
design is quite different from the old modal color picker in Carbon.
Where possible, at those places in your interfaces that you need to
pick a colour (e.g. a "Color..." button in a dialog, say), replace
those with NSColorWells which will interact with the floating modeless
color panel automatically. This will make your app much more standard
as a Cocoa app rather than trying to emulate the old way of doing
things.
If you really have no option, note that NSColorPanel subclasses
NSPanel, so it might be possible to run it modally or as a document
modal sheet though I've never tried it so I don't know if it's
possible. I see no built-in way to add OK/Cancel buttons but if you
can persuade it to run modally in some fashion you'll probably be able
to add these programatically to the panel.
