Inside my .xib, I've placed an NSColorWell inside an NSView, and connected an IBAction in the controller to the NSColorWell's Sent Actions (via File's Owner). I figured I would respond to a click in my controller and send activate to bring up the NSColorPanel.
But unlike other my controls, I'm not getting the IBAction called. Clicking invokes a drag action on the color. I noticed this control doesn't derive from NSActionCell (like all my other controls). What's the proper control that is supposed to be used to both display a color and invoke the NSColorWell when clicked?
(note: this is Xcode/IB 3.2.x)
You listed both osx and ios in the tags, but I'm guessing this is an OS X problem.
There is a "Bordered" checkbox in IB's Attributes Inspector for NSColorWell. This toggles between a button-style color well, which is what you're asking for, and a color well which you can only drag a color swatch from. Make sure that's checked and you'll get the action like you're expecting.
