Off the top of my head, I would simply fence the NSSlider to zero when its value is within a given range from that value: on a change event, if (say) -5 ≤ 0 ≤ 5, you can force the value to zero. You can then allow for finer tuning of the value by implementing the fencing only when the user moves the slides with the mouse, and instead allow any value when the user uses the arrow keys to reposition the slider's knob. —Mt. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
