macos - 右键单击 NSStatusBarButton 时调用 Action

Question

我正在寻找一种方法来检测 NSStatusBarButton右键单击(使用 Swift)并调用一个操作。

我目前是这样设置的:

let statusItem = NSStatusBar.systemStatusBar().statusItemWithLength(-1)

func applicationDidFinishLaunching(aNotification: NSNotification) {
    // Insert code here to initialize your application
    if let button = statusItem.button {
        button.image = NSImage(named: "myImage")
        button.alternateImage = NSImage(named: "myImage")
        button.action = Selector("myAction")
    }
}

我想到了使用 button.rightMouseDown(<#theEvent: NSEvent#>) (因为没有这样的“alternateAction”)但不幸的是，由于我刚刚开始编写 Mac 应用程序，所以我没有想出一些办法。

Update:

While searching for a way to do this I saw some threads telling to subclass a NSView but I don't se how this should work (This could be because I am really new to programming and don't even know how to "subclass"). Still I thought there was some easier way to use this since nearly every statusBar App that I know rects on right-clicks.

您可以子类化和重写mouseDown 方法，但是从 Mac OS X 10.10 (Yosemite) 开始，有一种更简单的方法:NSGestureRecognizer及其子类:

func applicationDidFinishLaunching(aNotification: NSNotification) {
    // Insert code here to initialize your application
    if let button = statusItem.button {
        button.image = NSImage(named: "myImage")
        button.alternateImage = NSImage(named: "myImage")
        button.action = Selector("myAction")

        // Add right click functionality
        let gesture = NSClickGestureRecognizer()
        gesture.buttonMask = 0x2 // right mouse
        gesture.target = self
        gesture.action = "myRightClickAction:"
        button.addGestureRecognizer(gesture)
    }
}

func myRightClickAction(sender: NSGestureRecognizer) {
    if let button = sender.view as? NSButton {
        // Handle your right click event here
    }
}
