cocoa - Using multiple NSSliderCell in a single NSSlider -

-

i'd create nsslider has 3 knobs, not one. i'm thinking can subclass nsslidercell , override tracking methods ensure 1 slider cell doesn't pass 1 next it.

that's easy enough do, i'm not sure how tell nsslider should have 3 cells show up, instead of one.

why not use 3 sliders? remove text , tick marks make them small , put them closely each other. using single slider 3 knobs give problems retrieving slider values.
