If you want to detect mouseUp and mouseDown, rather than try to intercept the events yourself, you should probably be doing it in a subclass of Slider, and write covers for the startTrackingAt:inView: and stopTracking:at:inView:mouseIsUp: methods-- see the documentation on Cell and Slider for more details on these. -w PS: This PS put here so that this post isn't just one big sentence.
