'How can I disable the close button?

I need some help with figuring out how to disable/hide the close, minimize, and resize buttons in OS X Cocoa and Swift 2. Here's the code I tried. I know it's for the Title Bar, but I thought I'd try it anyway:

self.window.titleVisibility = NSWindowTitleVisibility.Hidden;

Does any one know how to do that? I'm using Swift 2, OS X Cocoa, and Xcode 7.2. Thanks!

Also try;

    self.window!.standardWindowButton(NSWindow.ButtonType.closeButton)!.hidden = true
    self.window!.standardWindowButton(NSWindow.ButtonType.miniaturizeButton)!.hidden = true

etc.

In Xcode 9.1 you can use following in the ViewController, 

override func viewWillAppear() {

    self.view.window?.titleVisibility = .hidden
    self.view.window?.titlebarAppearsTransparent = true

    self.view.window?.styleMask.insert(.fullSizeContentView)

    self.view.window?.styleMask.remove(.closable)
    self.view.window?.styleMask.remove(.fullScreen)
    self.view.window?.styleMask.remove(.miniaturizable)
    self.view.window?.styleMask.remove(.resizable)

    //self.view.window?.isMovable = false
}

enter image description here

override func viewWillAppear() {

    self.view.window?.titleVisibility = .hidden
    self.view.window?.titlebarAppearsTransparent = true

    self.view.window?.styleMask.insert(.fullSizeContentView)

    //self.view.window?.styleMask.remove(.closable)
    self.view.window?.styleMask.remove(.fullScreen)
    self.view.window?.styleMask.remove(.miniaturizable)
    self.view.window?.styleMask.remove(.resizable)

    //self.view.window?.isMovable = false
}

See the NSWindow.styleMask property and the Window Style Masks.

Clearing the NSClosableWindowMask, NSMiniaturizableWindowMask, and NSResizableWindowMask flags will remove all of the buttons from a window's title bar.

window.styleMask &= ~(NSClosableWindowMask | NSMiniaturizableWindowMask | NSResizableWindowMask)

I find that the following effectively disables without completely hiding the close button:

self.view.window?.standardWindowButton(NSWindow.ButtonType.closeButton)?.isEnabled = false

Solution 5:[5]

a side note: do NOT disable "close" red button: apple will reject app saying:

"The user interface of your app is not consistent with the macOS Human Interface Guidelines. Specifically:

Specifically, the red light was disabled."

:(

If you are using Storyboards and you can change your window styleMask property inside an IBAction or viewDidLoad as follow:

NSApplication.sharedApplication().windows.first?.styleMask = NSTitledWindowMask   // | NSClosableWindowMask |  NSMiniaturizableWindowMask  | NSResizableWindowMask

If you would like to enable them again just uncomment the rest of the style mask:

NSApplication.sharedApplication().windows.first?.styleMask = NSTitledWindowMask | NSClosableWindowMask |  NSMiniaturizableWindowMask  | NSResizableWindowMask

Expanding on the accepted answer above by @JohnElemans, this is what worked for me when presenting modally using a storyboard segue on macOS 10.15:

// On NSViewController.viewDidAppear()

if let window = self.view.window {
    window.standardWindowButton(NSWindow.ButtonType.closeButton)?.isHidden = true
    window.standardWindowButton(NSWindow.ButtonType.miniaturizeButton)?.isHidden = true
    window.standardWindowButton(NSWindow.ButtonType.zoomButton)?.isHidden = true
}

I had to add the third line (NSWindow.ButtonType.zoomButton) to get rid of the green ('fullscreen') button.

If you are using Flutter? you can do like this?

import Cocoa
import FlutterMacOS
import window_manager


class MainFlutterWindow: NSWindow {
  override func awakeFromNib() {
    let flutterViewController = FlutterViewController.init()
    let windowFrame = self.frame
    self.contentViewController = flutterViewController
    self.setFrame(windowFrame, display: true)
  
  self.standardWindowButton(.closeButton)?.isHidden = true
  self.standardWindowButton(.miniaturizeButton)?.isHidden = true
  self.standardWindowButton(.zoomButton)?.isHidden = true


RegisterGeneratedPlugins(registry: flutterViewController)

super.awakeFromNib()
  }

    
  override public func order(_ place: NSWindow.OrderingMode, relativeTo otherWin: Int) {
            super.order(place, relativeTo: otherWin)
             hiddenWindowAtLaunch()
  }
}
