I'm trying something that I thought very easy. No chance.

I have a view, with a button. I want to set the cursor to pointing hand when move mouse over.

I tried the following, but no cursor change at all:

class ViewController: NSViewController {

    @IBOutlet weak var modalButton: NSButton!

    override func viewDidLoad() {
        super.viewDidLoad()
        let aCursor = NSCursor.pointingHandCursor()
        modalButton.addCursorRect(modalButton.bounds, cursor: aCursor)
        aCursor.setOnMouseEntered(true)
    }
}

In the documentation, they say to to invoke

invalidateCursorRectsForView:

.

but I get an unresolved identifier error when trying to do so.

I looked at Cursor doc, but very limited info.

It was in fact quite easy :

class ViewController: NSViewController {
    @IBOutlet weak var nameField: NSTextField!   
    @IBOutlet weak var modalButton: NSButton!
   
    private var pointingHand: NSCursor?
    private var openHand : NSCursor?
   
    override func viewDidLoad() {
        super.viewDidLoad()
       
        pointingHand = NSCursor.pointingHandCursor()
        modalButton.addCursorRect(modalButton.bounds, cursor: pointingHand!)
        pointingHand!.setOnMouseEntered(true)
        modalButton.addTrackingRect(modalButton.bounds, owner: pointingHand!, userData: nil, assumeInside: true)
       
        openHand = NSCursor.openHandCursor()
        modalButton.addCursorRect(modalButton.bounds, cursor: openHand!)
        openHand!.setOnMouseExited(true)
        modalButton.addTrackingRect(modalButton.bounds, owner: openHand!, userData: nil, assumeInside: true)
}

You need to call addCursorRect inside an override of resetCursorRects(). If the cursor never changes you probably won't need to call invalidateCursorRectsForView but if that still gives you problems you should post the actual code making the call.

When I try

override func resetCursorRects()

in the ViewController class,

class ViewController: NSViewController

I get an error message :

Method does not override any method from its superclass

So, where should I override this method ?

PS: I use a storyboard for this OS X project.
