Declaration
func knobRect(flipped: Bool) -> NSRectParameters
Return Value
The rectangle in which the knob is drawn, specified in the coordinate system of the NSSlider or NSMatrix with which the receiver is associated.
Discussion
The knob rectangle depends on where in the slider the knob belongs—that is, it depends on the receiver’s minimum and maximum values and on the value the position of the knob will represent.
