positioningRect
The rectangle within the positioning view relative to which the popover should be positioned.
Declaration
var positioningRect: NSRect { get set }Discussion
Popovers are positioned relative to a positioning view and are automatically moved when the location or size of the positioning view changes.
Sometimes it is desirable to position popovers relative to a rectangle within the positioning view. In this case, you must update the positioningRect property whenever this rectangle changes.
This property is exposed as a read-only binding.
