Hide NSWindow title bar - objective-c

Question

Is there a way to hide the titlebar in an NSWindow? I don't want to have to completely write a new custom window. I can't use NSBorderlessWindowMask because I have a bottom bar on my window, and using NSBorderlessWindowMask makes that disappear. I also tried using setContentBorderThickness:forEdge: with NSMaxYEdge and setting it to 0, that didn't work either.
Any help is appreciated

Answer 1

[yourWindow setStyleMask:NSBorderlessWindowMask];

Answer 2

Starting from OS X 10.10, you can hide title bar.
window1.titlebarAppearsTransparent = true
window1.titleVisibility = .Hidden
Maybe you want to override window style.
window1.styleMask = NSResizableWindowMask
| NSTitledWindowMask
| NSFullSizeContentViewWindowMask

Kind of Welcome screen NSWindow / NSViewController setup (Swift 4.1)
extension NSWindow {
enum Style {
case welcome
}
convenience init(contentRect: CGRect, style: Style) {
switch style {
case .welcome:
let styleMask: NSWindow.StyleMask = [.closable, .titled, .fullSizeContentView]
self.init(contentRect: contentRect, styleMask: styleMask, backing: .buffered, defer: true)
titlebarAppearsTransparent = true
titleVisibility = .hidden
standardWindowButton(.zoomButton)?.isHidden = true
standardWindowButton(.miniaturizeButton)?.isHidden = true
}
}
}
class WelcomeWindowController: NSWindowController {
private (set) lazy var viewController = WelcomeViewController()
private let contentWindow: NSWindow
init() {
contentWindow = NSWindow(contentRect: CGRect(x: 400, y: 200, width: 800, height: 472), style: .welcome)
super.init(window: contentWindow)
let frameSize = contentWindow.contentRect(forFrameRect: contentWindow.frame).size
viewController.view.setFrameSize(frameSize)
contentWindow.contentViewController = viewController
}
}
class WelcomeViewController: NSViewController {
private lazy var contentView = View()
override func loadView() {
view = contentView
}
init() {
super.init(nibName: nil, bundle: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
contentView.backgroundColor = .white
}
}
class View: NSView {
var backgroundColor: NSColor?
convenience init() {
self.init(frame: NSRect())
}
override func draw(_ dirtyRect: NSRect) {
if let backgroundColor = backgroundColor {
backgroundColor.setFill()
dirtyRect.fill()
} else {
super.draw(dirtyRect)
}
}
}
Result

What happens if you get the superview of the close button? Can you hide that?
// Imagine that 'self' is the NSWindow derived class
NSButton *miniaturizeButton = [self standardWindowButton:NSWindowMiniaturizeButton];
NSView* titleBarView = [miniaturizeButton superview];
[titleBarView setHidden:YES];

Answer 5

The only way I know would be to create a window without a titlebar (see
NSBorderlessWindowMask). Note that you can't (easily) create a window without a
titlebar in IB, so you will have to do a bit of work in code (there are a
couple of different approaches, you can probably figure it out).
A big drawback with using a window without a titlebar is that you're now on the
hook for much more of the standard appearance and behaviour - rounded corners
and such.

Answer 6

I had an experience that when I first set content view of my window and then set the window borderless:
[yourWindow setStyleMask:NSBorderlessWindowMask];
Nothing would appear in my window. So i first set the style mask and after that i've set the content view:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
// 1. borderless window
[[self window] setStyleMask: NSBorderlessWindowMask];
// 2. create the master View Controller
self.masterViewController = [[MasterViewController alloc] initWithNibName:#"MasterViewController" bundle:nil];
// 3. Add the view controller to the Window's content view
[self.window.contentView addSubview:self.masterViewController.view];
self.masterViewController.view.frame = ((NSView*)self.window.contentView).bounds;
}
And voila, the content of my window has appeared.

Select Window in storyboard or XIB and tick the red circled option.

Answer 8

You can use WAYInAppStoreWindow available on GitHub which works on Yosemite and Mavericks.

Answer 9

Swift
NSApp.mainWindow?.styleMask = .borderless
