I have an NSStatusBar application. This is my first in SwiftUI. And I need to know when the window is closed so that I can disable some of menu commands. I can use NSWindowDelegate with AppDelegate as follows.
import SwiftUI
@main
struct SomeApp: App {
@NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
@StateObject private var menuViewModel = MenuViewModel()
var body: some Scene {
WindowGroup {
ContentView()
.environmentObject(menuViewModel)
}
}
}
class AppDelegate: NSObject, NSApplicationDelegate, NSWindowDelegate {
private var menuViewModel = MenuViewModel()
func applicationDidFinishLaunching(_ notification: Notification) {
if let window = NSApplication.shared.windows.first {
window.setIsVisible(false)
window.delegate = self
}
}
func windowWillClose(_ notification: Notification) {
menuViewModel.windowClosed = true
}
}
When the window will close, MenuViewModel (ObservableObject) will receive a call, which I want my ContentView to receive. But, so far, it won't.
import SwiftUI
struct ContentView: View {
var body: some View {
ZStack {
...
...
}
.onReceive(statusBarViewModel.$windowClosed) { result in
// never called...
}
}
}
Can a SwiftUI View receive a call somehow when its window closes? Muchos thankos.
