Detect left and right mouse click on NSView


In Swift: I created a simple NSView and now want to execute different functions, depending on which mouseButton is pressed (left or right). how can I detect this?


Solution

  • You trap the corresponding mouseDown events

    import Cocoa
    
    class MyView : NSView {
        override func mouseDown(theEvent : NSEvent) {
            println("left mouse")
        }
    
        override func rightMouseDown(theEvent : NSEvent) {
            println("right mouse")
        }
    }
    

    See NSResponder for more magic.

    Swift 4

    import Cocoa
    
    class MyView : NSView {
        override func mouseDown(with theEvent: NSEvent) {
            print("left mouse")
        }
    
        override func rightMouseDown(with theEvent: NSEvent) {
            print("right mouse")
        }
    }
