prefersTrackingUntilMouseUp
Returns a Boolean value indicating whether the NSSliderCell continues to track the pointer until the next mouse up.
Declaration
class var prefersTrackingUntilMouseUp: Bool { get }Return Value
true if the NSSliderCell continues to track the pointer even after it leaves the cell’s tracking rectangle; otherwise, false. By default, this method returns true.
Discussion
If this method returns true, users retain control of the knob until they release the mouse button, even if they drag the pointer to the other side of the screen.
You should not call this method explicitly. Override it if you create a subclass of NSSliderCell that should track the mouse differently.
