Newbie - CoCoa - need a Dial/knob/NSSlider

[StephenT]

Hello,

I am new to most things MAC and now new to Programming and Cocoa. I have managed to get a NSSlider (Circular with dimple) to move and give its reading in a text field. however I can't get it to be larger in diameter. - I want various knobs/dials in my application and they will range in size from 1/2inch to 1.5inch in diameter.

The project is to mimic my radio facia - see pic here - Kenwood TS-2000, TS-2000X, TS-B2000 TS2000

While I am at it I will want to make small circles and small ovals in red/green/amber.

So question is how do I add picture/dawn elements to the window before I create classes and do the methods etc.

Cheers

Stephen
