Instance Property


The flags in effect at the mouse-down event that started the current tracking session.


var mouseDownFlags: Int { get }


The NSMatrix mouseDown(with:) method obtains these flags by sending a modifierFlags message to the event passed into mouseDown(with:). Use this property if you want to access these flags. This property is valid only during tracking; it isn’t useful if the target of the receiver initiates another tracking loop as part of its action method (as a cell that pops up a pop-up list does, for example).
