Hide NSWindow title bar

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 botto

Answer 1

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.

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.

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

Answer 4

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

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];

[yourWindow setStyleMask:NSBorderlessWindowMask];
