func applicationDidFinishLaunching(_ aNotification: Notification) { statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength) statusItem.button?.action = #selector(onClick) statusItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp]) menu = NSMenu() menu.addItem(NSMenuItem(title: "Quit", action: #selector(NSApplication.terminate(_:)), keyEquivalent: "q")) menu.delegate = self } @objc func onClick(sender: NSStatusItem) { let event = NSApp.currentEvent! if event.type == NSEvent.EventType.rightMouseUp { // right click, show quit menu statusItem.menu = menu; menu.popUp(positioning: nil, at: NSPoint(x: 0, y: statusItem.statusBar!.thickness), in: statusItem.button) } else { // main click } } @objc func menuDidClose(_ menu: NSMenu) { // remove menu when closed so we can override left click behavior statusItem.menu = nil }
OK Got exercise working but status bar truncates length of time. Setting a length of 53 seems to be th e max - any larger an the display fails. Have not worked out how to user a smaller font so it will not overflow the space available.
Mouse Location
From 2015...
If you would like to monitor events on any window when your app is active, you can add a LocalMonitorForEvents matching mouseMoved mask and if it is not active a GlobalMonitorForEvents. Note that you need set to your window property acceptsMouseMovedEvents to true
import Cocoa
class ViewController: NSViewController {
lazy var window: NSWindow = self.view.window! var mouseLocation: NSPoint { NSEvent.mouseLocation } var location: NSPoint { window.mouseLocationOutsideOfEventStream } override func viewDidLoad() { super.viewDidLoad() NSEvent.addLocalMonitorForEvents(matching: [.mouseMoved]) { print("mouseLocation:", String(format: "%.1f, %.1f", self.mouseLocation.x, self.mouseLocation.y)) print("windowLocation:", String(format: "%.1f, %.1f", self.location.x, self.location.y)) return $0 } NSEvent.addGlobalMonitorForEvents(matching: [.mouseMoved]) { _ in print(String(format: "%.0f, %.0f", self.mouseLocation.x, self.mouseLocation.y)) } } override func viewWillAppear() { super.viewWillAppear() window.acceptsMouseMovedEvents = true }
}
You can get the current mouse location in this way:
Declare this in your view controller class:
var mouseLocation: NSPoint? { self.view.window?.mouseLocationOutsideOfEventStream }
Then, you can get the current mouse location and convert in your desired view coordinates:
if let currentMouseLocation = self.mouseLocation{ let pointInTargetView = self.**targetView**.convert(currentMouseLocation, from: self.view) }
Get Coordinates of TextField or any View in SwiftUI
Here is a demo of how specific view coordinates can be read (see helpful comments inline)
struct DemoReadViewOrigin: View { @State private var someNumber1 = "1000" @State private var someNumber2 = "2000" //bunch more @State private var enteredNumber = "Some Text at the Top" @State var value: CGFloat = 0 var body: some View { ScrollView { VStack { Spacer() Text("\(enteredNumber)") Spacer() Group { //1 TextField("Placeholder", text: $someNumber1) .keyboardType(.default) .textFieldStyle(RoundedBorderTextFieldStyle()) .background(GeometryReader { gp -> Color in let rect = gp.frame(in: .named("OuterV")) // < in specific container // let rect = gp.frame(in: .global) // < in window // let rect = gp.frame(in: .local) // < own bounds print("Origin: \(rect.origin)") return Color.clear }) //this does not work .onTapGesture { } TextField("Placeholder", text: $someNumber2) .keyboardType(.default) .textFieldStyle(RoundedBorderTextFieldStyle()) }//group 1 //bunch more Button(action: { self.enteredNumber = self.someNumber1 self.someNumber1 = "" // UIApplication.shared.endEditing() }) { Text("Submit") } .padding(.bottom, 50) }//outer v .coordinateSpace(name: "OuterV") // << declare coord space .padding(.horizontal, 16) .padding(.top, 44) }//Scrollview or Form // .modifier(AdaptsToSoftwareKeyboard()) } }
