Cocoa Interface Builder's 'Attributes Inspector' like window

Answer 1

There's no built-in Cocoa controls to do this. You're going to have to write some custom views which replicate the functionality.

There some good advice for creating custom controls in the answers to this question: http://stackoverflow.com/questions/380875/looking-for-info-on-custom-drawing-of-interface-components-cocoa

If you need additional help, I recommend you ask smaller, more specific questions explaining what you've tried and what hasn't worked.

Answer 2

InspectorKit is FOSS on github.
