是否仅在NSStatusBarButton上显示NSMenu右击？

原学程将引见能否仅在NSStatusBarButton上显示NSMenu右打？的处置办法，这篇学程是从其余处所瞅到的，而后减了1些海外法式员的疑问与解问，愿望能对于您有所赞助，佳了，上面开端进修吧。

成绩描写

我有以下代码：(不妨复制粘贴到新的MacOS项目)

import Cocoa
import SwiftUI

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
 var statusBarItem: NSStatusItem!

 func applicationDidFinishLaunching(_ aNotification: Notification) {

  let statusBar = NSStatusBar.system
  statusBarItem = statusBar.statusItem(
withLength: NSStatusItem.squareLength)
  statusBarItem.button?.title = "?"

  // Setting action
  statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
  statusBarItem.button?.sendAction(on: [.leftMouseUp])

  let statusBarMenu = NSMenu(title: "Status Bar Menu")
  statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")

  statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")

  // Setting menu
  statusBarItem.menu = statusBarMenu
 }

 @objc func statusBarButtonClicked(sender: NSStatusBarButton) {
  let event = NSApp.currentEvent!

  if event.type ==  NSEvent.EventType.rightMouseUp {
print("Right click!")
  } else {
print("Left click!")
  }
 }

 @objc func orderAnApple() {
  print("Ordering a apple!")
 }


 @objc func cancelAppleOrder() {
  print("Canceling your order :(")
 }

}

增除此言后：

statusBarItem.menu = statusBarMenu

所需行动：右打菜单翻开，左打菜单未翻开，操纵被触收。
怎样完成？

编纂

我在@red_menace批评的赞助下胜利完成了预期的行动：

import Cocoa
import SwiftUI

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
 var statusBarItem: NSStatusItem!
 var menu: NSMenu!

 func applicationDidFinishLaunching(_ aNotification: Notification) {

  let statusBar = NSStatusBar.system
  statusBarItem = statusBar.statusItem(
withLength: NSStatusItem.squareLength)
  statusBarItem.button?.title = "?"

  // Setting action
  statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
  statusBarItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp])

  let statusBarMenu = NSMenu(title: "Status Bar Menu")
  statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")

  statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")

  // Setting menu
  menu = statusBarMenu
 }

 @objc func statusBarButtonClicked(sender: NSStatusBarButton) {
  let event = NSApp.currentEvent!

  if event.type ==  NSEvent.EventType.rightMouseUp {
statusBarItem.popUpMenu(menu)
  } else {
print("Left click!")
  }
 }

 @objc func orderAnApple() {
  print("Ordering a apple!")
 }


 @objc func cancelAppleOrder() {
  print("Canceling your order :(")
 }

}

有甚么方法经由过程新的API完成所需的行动？

推举谜底

显示菜单的平日方法是将菜单分派给状况项，在单打状况项按钮时将在个中显示该菜单。因为popUpMenu已弃用，是以须要另外一种方法去显示分歧前提下的菜单。假如愿望右打应用现实的状况项菜单，而没有是仅在状况项地位显示高低文菜单，则状况项菜单属性不妨坚持为空，直到您想要显示它。

我对于您的代码停止了修正，使statusBarItem以及statusBarMenu援用坚持分别，仅将菜单添减到单打的操纵办法中的状况项。在操纵办法中，1旦添减了菜单，便会在状况按钮上履行正常的单打以增除菜单。因为在单打按钮时状况项将一直显示其菜单，是以添减了NSMenuDelegate办法，以就在菜单封闭时将Menu属性树立为nil，进而复原原初操纵：

import Cocoa

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate, NSMenuDelegate {
 // keep status item and menu separate
 var statusBarItem: NSStatusItem!
 var statusBarMenu: NSMenu!

 func applicationDidFinishLaunching(_ aNotification: Notification) {
  let statusBar = NSStatusBar.system
  statusBarItem = statusBar.statusItem(withLength: NSStatusItem.squareLength)
  statusBarItem.button?.title = "?"

  statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
  statusBarItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp])

  statusBarMenu = NSMenu(title: "Status Bar Menu")
  statusBarMenu.delegate = self
  statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")
  statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")
 }

 @objc func statusBarButtonClicked(sender: NSStatusBarButton) {
  let event = NSApp.currentEvent!
  if event.type ==  NSEvent.EventType.rightMouseUp {
print("Right click!")
statusBarItem.menu = statusBarMenu // add menu to button...
statusBarItem.button?.performClick(nil) // ...and click
  } else {
print("Left click!")
  }
 }

 @objc func menuDidClose(_ menu: NSMenu) {
  statusBarItem.menu = nil // remove menu so button works as before
 }

 @objc func orderAnApple() {
  print("Ordering a apple!")
 }

 @objc func cancelAppleOrder() {
  print("Canceling your order :(")
 }

}
