检测 NSStatusItem 上的左键和右键单击事件 (Swift)

Question

我正在构建一个状态栏应用程序，并希望根据用户是向左还是向右单击来调用不同的操作。这是我目前所拥有的：

var statusItem = NSStatusBar.system().statusItem(withLength: -1)
statusItem.action = #selector(AppDelegate.doSomeAction(sender:))

let leftClick = NSEventMask.leftMouseDown
let rightClick = NSEventMask.rightMouseDown

statusItem.button?.sendAction(on: leftClick)
statusItem.button?.sendAction(on: rightClick)

func doSomeAction(sender: NSStatusItem) {
    print("hello world")
}

我的函数没有被调用，我找不到原因。感谢您的帮助！

Answer 1

你试过了吗：

button.sendAction(on: [.leftMouseUp, .rightMouseUp])

然后查看doSomeAction()函数中按下了哪个鼠标按钮？

所以它看起来像...

let statusItem = NSStatusBar.system().statusItem(withLength: NSSquareStatusItemLength)

func applicationDidFinishLaunching(_ aNotification: Notification) {

    if let button = statusItem.button {
        button.action = #selector(self.doSomeAction(sender:))
        button.sendAction(on: [.leftMouseUp, .rightMouseUp])
    }

}

func doSomeAction(sender: NSStatusItem) {

    let event = NSApp.currentEvent!

    if event.type == NSEvent.EventType.rightMouseUp {
        // Right button click
    } else {
        // Left button click
    }

}

感谢@dbrownjave 注意到 Swift 4 从 NSEventType.rightMouseUp 到 NSEvent.EventType.rightMouseUp 的变化。

更新：SWIFT 4

我更新了（Craig Francis）的回答

func doSomeAction(sender: NSStatusItem) {

    let event = NSApp.currentEvent!

    if event.type == NSEvent.EventType.rightMouseUp{
        // Right button click
    } else {
        // Left button click
    }
