The application is background only
This is a timer app
A dialog box(NSAlert) pops up after a specified time to prompt the user. How to ensure NSAlert on window top?
StatusBarMenu
class StatusBarMenu: NSObject {
private let statusItem: NSStatusItem!
init(statusItem: NSStatusItem) {
self.statusItem = statusItem
}
private func createMenu() {
selft.addMenuItem()
}
func refresh() {
self.statusItem.menu?.removeAllItems()
self.createMenu()
}
func addMenuItem() {
let item = NSMenuItem(title: "show alert", action: #selector(self.showAlert), keyEquivalent: "")
item.target = self
self.statusItem.menu?.addItem(item)
}
#objc func showAlert() {
DispatchQueue.main.sync {
let alert = NSAlert()
alert.icon = NSImage(named: "Alert")
alert.messageText = title
alert.informativeText = text
alert.alertStyle = .informational
alert.addButton(withTitle: "ok")
alert.runModal()
}
}
}
I found an answer to my own question:
alert.window.level = .floating
This works.
This is an example of how to keep NSAlert window on top
alert = NSAlert.alertWithMessageText_defaultButton_alternateButton_otherButton_informativeTextWithFormat_(
title, ok, cancel, other, message)
alert.setAlertStyle_(0) # informational style
# customize# floating window
alert.window().setLevel_(3)

The first and second level menus are matched one by one through the NSmenuItem's title invocation array, and the first level menu also works properly to display data.
But once the secondary menu into NSView, only the first item will be show the data, the rest are blank, tried a lot of methods, did not succeed, please guide me, how to deal with?
update method:
func updateData() {
for city in cites {
let airQualityApi = AirQualityApi()
airQualityApi.fetchData(query: city, success: {airQuality in
if let airQualityMenyItem = self.statusMenu.item(withTitle: city){
airQualityMenyItem.title = airQuality.description
self.airQualityDetailView.update(airQuality: airQuality)
}
})
}
}
Sec level NSView update method:
func update(airQuality: AirQuality) {
DispatchQueue.main.sync {
self.cityName.stringValue = airQuality.city
self.airQuality.intValue = Int32(airQuality.aqi)
}
}
add NSMenuItem:
override func awakeFromNib() {
updateData()
let icon = NSImage(named: "icon")
icon?.isTemplate = true
if let button = statusItem.button {
button.image = icon
}
statusItem.menu = statusMenu
//let editMenuItem = NSMenuItem()
//editMenuItem.title = "showAqi"
for i in 0 ... cites.count - 1 {
let mainMenu = NSMenuItem(title: cites[i], action: .none, keyEquivalent: "")
statusMenu.insertItem(mainMenu, at: i)
let sub = NSMenu()
let subMenu = NSMenuItem(title: mainMenu.title, action: .none, keyEquivalent: "")
subMenu.view = airQualityDetailView
//print(subMenu.title)
statusMenu.setSubmenu(sub, for: mainMenu)
sub.addItem(subMenu)
//sub.insertItem(subMenu, at: 0)
}
}

I have the following code: (can be copy-pasted to New macOS project)
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 :(")
}
}
Actual behaviour: Menu opens on both left and right click, statusBarButtonClicked is not triggered.
After removing this line:
statusBarItem.menu = statusBarMenu
statusBarButtonClicked triggers on left click, menu doesn't show up (as expected)
Desired behaviour: Menu opens on right click, on left click menu doesn't open, action is triggered. How do I achieve it?
EDIT
I managed to achieve desired behavior with help of #red_menace comment:
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 :(")
}
}
But Xcode says that openMenu func is deprecated in 10.14 and tells me to Use the menu property instead. Is there I way to achieve desired behaviour with new API?
The usual way a to show a menu is to assign a menu to the status item, where it will be shown when the status item button is clicked. Since popUpMenu is deprecated, another way is needed to show the menu under different conditions. If you want the right click to use an actual status item menu instead of just showing a contextual menu at the status item location, the status item menu property can be kept nil until you want to show it.
I've adapted your code to keep the statusBarItem and statusBarMenu references separate, only adding the menu to the status item in the clicked action method. In the action method, once the menu is added, a normal click is performed on the status button to drop the menu. Since the status item will then always show its menu when the button is clicked, an NSMenuDelegate method is added to set the menu property to nil when the menu is closed, restoring the original operation:
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 :(")
}
}
Here is possible approach. There might be more accurate calculations for menu position, including taking into account possible differences of userInterfaceLayoutDirection, but the idea remains the same - take possible events under manual control and make own decision about what to do on each event.

Learning from the great answers already given in here I came up with an alternative.
The advantage of this approach is that you only set the NSMenu once and don't have to juggle with setting it or removing it anymore.
Setting up the NSStatusBarButton
let status = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
status.button!.image = NSImage(named: "status")
status.button!.target = self
status.button!.action = #selector(triggerStatus)
status.button!.menu = /* your NSMenu */
status.button!.sendAction(on: [.leftMouseUp, .rightMouseUp])
Receiving the action
#objc private func triggerStatus(_ button: NSStatusBarButton) {
guard let event = NSApp.currentEvent else { return }
switch event.type {
case .rightMouseUp:
NSMenu.popUpContextMenu(button.menu!, with: event, for: button)
case .leftMouseUp:
/* show your Popup or any other action */
default:
break
}
}
I’m building a status bar app and want to call different actions depending on if the user clicked left or right. Here’s what I have so far:
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")
}
My function is not called and I couldn’t find our why. I appreciate any help!
Have you tried:
button.sendAction(on: [.leftMouseUp, .rightMouseUp])
Then seeing which mouse button was pressed in the doSomeAction() function?
So it will look something like...
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
}
}
Thanks to #dbrownjave for noticing the change in Swift 4 from NSEventType.rightMouseUp to NSEvent.EventType.rightMouseUp.

I need to show an alert box when the user quits the application by clicking on the x button.How can I hook on to the exit event of the application and show an alert or view controller via a segue
performSegue(withIdentifier: "segue", sender: nil)
Please advice..
I know you want to use a segue to do this because they're just so convenient, but segues can't be done in a storyboard going from app delegate events like "applicationWillResignActive" (going to background) or "applicationWillBecomeActive" (becoming foreground again).
The correct way to do this would be via an alert. And you'd likely want to do this in applicationShouldTerminate, since you probably want to A) be able to abort quitting if you have a good reason not to quit just yet or B) give the user a choice whether or not to really quit.
Here's how it would look in swift 4:
var licenseWindowController : LicenseWindowController?
func dialogOKCancel(question: String, text: String) -> Bool {
let alert = NSAlert()
alert.messageText = question
alert.informativeText = text
alert.alertStyle = .warning
alert.addButton(withTitle: "OK")
alert.addButton(withTitle: "Cancel")
return alert.runModal() == .alertFirstButtonReturn
}
func applicationShouldTerminate(_ sender: NSApplication) -> NSApplication.TerminateReply {
let answer = dialogOKCancel(question: "Ok?", text: "Should we really quit?")
if answer == true
{
return .terminateNow
} else {
func applicationShouldTerminate(_ sender: NSApplication) -> NSApplication.TerminateReply {
let answer = dialogOKCancel(question: "Ok?", text: "Should we really quit?")
if answer == true
{
return .terminateNow
} else {
// to bring up a window from your storyboard...
let mainStoryboard = NSStoryboard.init(name: NSStoryboard.Name(rawValue: "Main"), bundle: nil)
self.licenseWindowController = mainStoryboard.instantiateController(withIdentifier: NSStoryboard.SceneIdentifier(rawValue: "LicenseWindowController")) as? LicenseWindowController
if let actualLicenseWC = self.licenseWindowController
{
actualLicenseWC.showWindow(self)
}
return .terminateCancel
}
}
Swift 3
var licenseWindowController : LicenseWindowController?
func dialogOKCancel(question: String, text: String) -> Bool {
let alert = NSAlert()
alert.messageText = question
alert.informativeText = text
alert.alertStyle = .warning
alert.addButton(withTitle: "OK")
alert.addButton(withTitle: "Cancel")
return alert.runModal() == NSAlertFirstButtonReturn
}
func applicationShouldTerminate(_ sender: NSApplication) -> NSApplicationTerminateReply {
let answer = dialogOKCancel(question: "Ok?", text: "Should we really quit?")
if answer == true
{
return .terminateNow
} else {
let mainStoryboard = NSStoryboard.init(name: "Main", bundle: nil)
self.licenseWindowController = mainStoryboard.instantiateController(withIdentifier: "LicenseWindowController") as? LicenseWindowController
if let actualLicenseWC = self.licenseWindowController
{
actualLicenseWC.showWindow(self)
}
return .terminateCancel
}
}
In your appdelegate you should be able to put your code into applicationWillTerminate and make the message appear there.
Edit: You would probably be better off using a modal alert instead of a segue.
