This must have been asked before, but after Googling I still can't find the answer.
How do you change the color of the title bar (The bar that you can click and drag around with the close, minimize and maximize buttons) to a different color than the default gray in Cocoa?
If you set the background color of a "textured" window (a distinction that isn't really all that visible in Snow Leopard) that color will be applied to the titlebar as well. This is what Firefox does.
I would recommend though not having a real titlebar (i.e. setting your window to have no titlebar) and using +[NSWindow standardWindowButton:forStyleMask:] and putting your own buttons in the "titlebar". This allows you more control and is way way less hacky.
If it's a panel, you can change it to black by instantiating it as a HUD window.
Otherwise, you can't. Ever notice how there aren't any Aqua windows with different-colored title bars roaming around in other apps? This is why.
The only other way to change the appearance of the title bar (without relying on private implementation details such as the existence of a frame view) is to make the window borderless and create its title bar and window buttons from the ground up.
If you go with Colin's approach of making the window textured in interface builder (check box in the attributes of the window), here's the line to change the background color of the window you'd put in this function of the appDelegate.m file
//In this function --->
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
//type this
[_window setBackgroundColor: NSColor.whiteColor];
If you don't mind private API, you could subclass NSThemeFrame.
Setting title bar appears as transparent
self.window.titlebarAppearsTransparent = YES;
And setting window background color as you wish

How do I show resize indicators for an NSWindow without Titlebar?
I created a new Xcode project(for Mac app) with storyboard. I just disabled the checkbox Title Bar in Appearance(It hides the Title bar of NSwindow).
The strange thing was, after disabling the TitleBar, NSWindow was not showing resize indicators while mouse was above the window edges. Although if I drag at edges it was resizing.
I guess this is a bug, because if the window can be resized by dragging the mouse over edges, it must show the resize indicators.
As it can be seen in the image, the resize indicators are seen after user drags the window, but many users would think that since there is no resize indicator, the window is not resizable.
I've fixed this issue by subclassing NSWindow and overriding canBecomeKeyWindow to return YES:
#import "MyWindow.h"
#implementation MyWindow
- (BOOL)canBecomeKeyWindow {
return YES;
}
#end
Not updating resize cursors in this case looks like Apple bug. Documentation states "The value of canBecomeKeyWindow property is YES if the window has a title bar or a resize bar, or NO otherwise.", so I expect that canBecomeKeyWindow will return YES for resizable window. But it doesn't.
UPD: Checked on 10.10.5. Hopefully, you will have same behaviour on 10.11.
I have not checked this, but you could set the resize indicators manually. I think I would add four NSTrackingAreas to the windows contentView subclass (one for each side of the window, only few pixels in height/width).
In the mouseEntered() method, create a new NSCursor object for the appropriate mouse position. Remember that the position could change, so use the mouseMoved() method as well.
On mouseExited() reset the cursor.
Again, I have not tried this, but it should work.
PS: Don't forget to file a radar on this ;)
The System Preferences app feature a combined title bar and toolbar with vertically centered buttons and the title. I am trying to mimic this exactly in my app. I have been able to combine the title bar and toolbar using Interface Builder (on the NSWindow check Title Bar and Unified Title and Toolbar), but this does not center the content vertically. I discovered via this question you can simply set the window's titleVisibility to NSWindowTitleHidden which will vertically center the stoplight buttons. Unfortunately this of course hides the title. How can one vertically center content in the unified titlebar/toolbar and also show the window's title just like System Preferences - either in IB or programmatically?
I ended up setting titleVisibility to NSWindowTitleHidden and manually created an NSView that contains an NSTextField that mimics the standard title appearance, providing that to the window's addTitlebarAccessoryViewController method. Still would like to find a better solution to use the default title appearance, if possible.
I used WAYAppStoreWindow on GitHub to do this. I created a fork of the WAYWindow subproject to vertically centre the document title since this wasn't supported. This means any applied themes/appearances are honoured.
I am in the process of creating a small image editor.
What I aim, is to create a window with transparent titlebar, but not what contains inside the window.
I have check HUD Window, but it's really is a panel, not a window. And I am missing the regular close,maximize and minimize button.
Is there anyway to create such window?
Or can we modify HUD to hold regular close,max and min button?
Thanks so much in advance!

Use a standard borderless window approach and provide a content view that draws something. Even if the content view's bounds rect is just filled with [NSColor whiteColor].
Update: Re-reading, I see you seem to be asking for just a transparent title bare but still with the window controls. See this StackOverflow question for an approach at customizing a window's title bar. Careful, though - I'm not sure this would be accepted into the App Store. Best to have a backup plan in case it's not.
Here is what I found that match to what I want : window trasparency
The trick is making the main window transparent, but not the content by creating a special view for this.
I am using standard HUD window (Drag and drop from IB Library). But I don't see any control to set the transparency of this HUD window.
I also tried to customize NSPanel to create HUD window . But whatever the alpha value I set. It takes default alpha value. One more problem in this approach is I think I need to draw tittle bar.
Any solution or alternate solution is appreciated.
This page has an example that subclasses NSPanel and draws an HUD Window completely from scratch. The background color/alpha can easily be changed from HUDWindow.m.
I want to change the height of an NSWindow titlebar.
Here are some examples:
And…
I could use an NSToolbar, but the problem is that I can't place views very height (For example: I can't place the segmentedControl higher than in the picture because there is still the titlebar)
If I remove the titlebar I can't place a NSToolbar and the window isn't movable.
Have you any ideas?
This is much easier than one would think. I too went on a quest to do something similar for my app.
Real App Store app:
My App Store app look-alike:
No disrespect to INAppStoreWindow, it is a very good implementation and solid. The only draw back I saw from it though was that there was a lot of drawing code along with hardcoded settings for the TitleBar colors which Apple can adjust at anytime.
So here is how I did it:
A) Create a standard window with a Title Bar, Close, Minimize, Shadow, Resize, Full Screen - Primary Window all set.
Note: You do not need a textured window nor should you set a title
B) Next add a standard toolbar with these settings:
Icon Only
Visible at Launch - ON
Customizable - OFF
Separator - ON
Size - Regular
Remove all the Toolbar Items and add only these in the following order
NSSegmentControl (51 x 24) -- | Flexible Space | -- NSSearchField (150 x 25)
C) In your content View directly under the toolbar add a regular sized NSButton set like so:
Bordered - OFF
Transparent - OFF
Title -
Image -
Position - Text below the button
Font - System Small 11
Ok, pretty easy so far, right?!
In your Window Controller or app delegate....
setup IBOutlet(s) to your NSButton(s)
Note: Remember to hook up your IBOutlet in interface builder
Ok don't be scared we have to write a tiny bit of code now:
In awakeFromNib or windowDidLoad....
Get the content views' superview (aka NSThemeView)
Remove your button from its superView
Set the frame of your button
Add the button back to the theme view
So the code would look similar to this:
NSView *themeView = [self.contentView superview];
NSUInteger adj = 6;
[self.btnFeatured removeFromSuperview];
self.btnFeatured.frame = NSMakeRect( self.btnFeatured.frame.origin.x,
self.window.frame.size.height - self.btnFeatured.frame.size.height - adj,
self.btnFeatured.frame.size.width, self.btnFeatured.frame.size.height);
[themeView addSubview:self.btnFeatured];
That's it! You can use your outlet to enable/disable your button, setup a mask image when selected, enable/disable the toolbar or even hide everything and add a window title. All of this without worry if Apple changes their standard Window Titlebars.
P.S. No private frameworks were used in this posting whatsoever!
INAppStoreWindow is a NSWindow subclass, it tell you how to change the height of title bar.
https://github.com/indragiek/INAppStoreWindow
http://iloveco.de/adding-a-titlebar-accessory-view-to-a-window/
This example tells you how to add buttons in the title bar.
You'd have to subclass NSWindow and do a custom window frame drawing. It's not only about a titlebar. It's about whole window frame (so you can, actually, put close/minimize/zoom buttons at the bottom if you wish).
A good starter is at "Cocoa with love" website.
There are a few new solutions based on INAppStoreWindow and without warning and log message, for anyone who wants to change the height of NStitlebar, change the position of traffic light, add an item(e.g. a NSbutton) on NStitlebar and change its position, please check below.
