What Controls/Objects Does iTunes Use?

I'm trying to create a Mac OS app with a simialar layout to iTunes. In my iTunes configuraton, I have a column of selectors (Artists, Albums, etc.) on the left hand side of the window that control what appears on the right hand side. I'm guessing the right hand side is made up of various views. Artists looks like a vertical split view. Songs looks like a table view. Is that correct?


I'm not at all sure about the left side. Are the selectors a type of button or are they just text that accepts click events? Also, is there anything special about their contraner? Is it just a generic view?
