Hi
When adding new file to a macOS project theres a MainMenu option, whats the use of it ? I mean each project have its pre mad Main Menu
so whats the use of this item and how to use it if requiered ?
Kindest Regards
whatever changed i do to secondary menu in user interface .xib file it wont reflect at run time
Can you tell exactly what change ?
Did you notice that the help menu disappeared ?
And about says "About NewApplication", as defined
I also added a menu item below About. And it shows when I run.
So I just don't understand what you mean.
also if I need the ne menu ti be hidden and relaod the old one when windows lost and get focus what function I shoud overrride ?
To be hidden. Do you mean replaced by the original one ?
That is what happens when window closes
override func viewDidDisappear() {
super.viewDidDisappear()
let appDelegate = NSApplication.shared.delegate as! AppDelegate
NSApp.mainMenu = appDelegate.currentMainMenu
}To do the same when select /+ deselect window, use windowDidBecomeKey, as follows:
AppDelegate :
import Cocoa
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
var currentMainMenu: NSMenu?
func applicationDidFinishLaunching(_ aNotification: Notification) {
// Insert code here to initialize your application
currentMainMenu = NSApp.mainMenu
}
func applicationWillTerminate(_ aNotification: Notification) {
// Insert code here to tear down your application
}
func setSecondaryMenu() {
Bundle.main.loadNibNamed("SecondaryMenu", owner: self, topLevelObjects: nil)
let items = NSApplication.shared.mainMenu?.items
let firstItem = items?[0]
let subMenu = firstItem?.submenu
subMenu?.title = "NewApplication " // Only this can change the menu title
subMenu?.font = NSFont.boldSystemFont(ofSize: 0)
}
}Add the delegate func to S1W2WC
import Cocoa
class S1W2WC: NSWindowController, NSWindowDelegate {
override func windowDidLoad() {
super.windowDidLoad()
// Implement this method to handle any initialization after your window controller's window has been loaded from its nib file.
}
func windowDidMove (_ notification: Notification) {
let newOrigin = self.window!.frame.origin
print("S1W2WC Window Did Move:", newOrigin)
}
func windowDidResize (_ notification: Notification) {
let newSize = self.window!.frame.size
print("S1W2WC Window Did Resize:", newSize)
}
func windowDidResignKey(_ notification: Notification) { // NEW
let appDelegate = NSApplication.shared.delegate as! AppDelegate
NSApp.mainMenu = appDelegate.currentMainMenu
}
func windowDidBecomeKey(_ notification: Notification) { // NEW
let appDelegate = NSApplication.shared.delegate as! AppDelegate
appDelegate.setSecondaryMenu()
}
}In ViewController, no more need to set delegate:
import Cocoa
class ViewController: NSViewController { // }, NSWindowDelegate { // NSWindowDelegate NO MORE NEEDED
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
print("ViewController")
self.view.window?.isOpaque = false
// self.view.window?.backgroundColor = .clear
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
override func viewWillAppear() {
super.viewWillAppear()
}
override func viewDidLayout() {
// self.view.window!.delegate = self // NO MORE NEEDED
}
@IBAction func ShowWindow(_ sender: Any) {
}
/* Ammar S. Mitoori .. Show Window2 in Main Storboard by code */
@IBAction func ShowWindowByCode(_ sender: Any) {
let storyboard = NSStoryboard(name: "Main", bundle: nil)
if let windowController = storyboard.instantiateController(withIdentifier: "S1W2") as? S1W2WC // NSWindowController
{
windowController.showWindow(self)
}
}
/* Ammar S. Mitoori .. Show Window1 in Secondary Storboard by code */
@IBAction func ShowWindow2S2ByCode(_ sender: Any) {
let storyboard = NSStoryboard(name: "Secondary", bundle: nil)
if let windowController = storyboard.instantiateController(withIdentifier: "S2W1") as? NSWindowController
{
windowController.showWindow(self)
}
}
/* NO MORE NEEDED
func windowDidMove (_notification: Notification){
let newOrigin = self.view.window!.frame.origin
print("ViewController Window Did Move:", newOrigin)
}
func windowDidResize (_notification: Notification){
let newSize = self.view.window!.frame.size
print("ViewController Window Did Resize:", newSize)
}
*/
}SecondVC can be slightly simplified:
import Cocoa
class SecondVC: NSViewController { // , NSWindowDelegate {
var parentWindowController: NSWindowController? // Helps keep a reference to the controller: needed to avoid reference to be released and let notifications flow
override func viewDidLoad() {
super.viewDidLoad()
// Do view setup here.
}
override func viewDidAppear() {
super.viewDidAppear()
parentWindowController = self.view.window!.windowController // Needed, otherwise notification do not go through
// 23.11.2019 self.view.window!.delegate = parentWindowController as! S1W2WC. IN FACT, NOT NEEDED
let appDelegate = NSApplication.shared.delegate as! AppDelegate
appDelegate.setSecondaryMenu()
}
// func windowDidMove(_ notification: Notification) { // NSWindowDelegate function NOT NEEDED
// let newOrigin = self.view.window!.frame.origin
// print("windowDidMove new origin:", newOrigin)
//
// }
//
// func windowDidResize(_ notification: Notification) { // NSWindowDelegate function NOT NEEDED
// let newSize = self.view.window!.frame.size
// print("windowDidResize new size:", newSize)
// }
override func viewDidDisappear() {
super.viewDidDisappear()
// Maybe superfluous now that we have the func in WindowController
let appDelegate = NSApplication.shared.delegate as! AppDelegate
NSApp.mainMenu = appDelegate.currentMainMenu
}
}I tested, it works. Tell if that works now for you.
