I have a typical cocoa application. There is a toolbar item on the toolbar, current behaviour is to draw a rectangle in the view of main window whenever this toolbar item is clicked.
However, now there is a new requirement: user needs to be able to drag this toolbar item to a position in the main view so that the rectangle will be drawn on that position (where user release the mouse to drop the toolbar item).
I checked the apple dev document at https://developer.apple.com/library/mac/documentation/cocoa/reference/applicationkit/classes/NSToolbarItem_Class/Reference/Reference.html and https://developer.apple.com/library/mac/documentation/cocoa/Conceptual/Toolbars/Toolbars.html#//apple_ref/doc/uid/10000109i , but cannot find any method related to this.
Could anyone know how to do it? Thanks.

I want to have a window with a hidden title, as seen in Safari or Xcode, but using a titlebar accessory view instead of a toolbar (I want more control over arrangement and content than a toolbar provides). Is this doable?
I haven't quite been able to make it work. If I set my window's titleVisibility to hidden, and my accessory view's layoutAttribute is bottom, then the title area is empty except for the standard close/minimize/zoom buttons, and my accessory view appears below that.
If I change the layoutAttribute to right, then my accessory view appears to the right of the standard buttons where I want it, but the bottom is cut off because the title bar isn't tall enough, and the view also doesn't resize horizontally with the window.
Is there a way to make this work? Or do I have to use a toolbar?
Update: I used Xcode's visual debugger to examine Xcode's own title bar, and found that it is using a toolbar. The debugger refuses to attach to Safari, so I'm left wondering how it does the new tab button. I imagine that button is a right-pinned accessory view, and the rest is a normal toolbar. Safari's toolbar is still customizable, so that seems most likely.
I decided to go ahead and use a toolbar, and it's working pretty well.
I took my NSTitleBarAccessoryController subclass and made it inherit from NSViewController instead.
I created a non-customizable toolbar for my window, with a single "Image Toolbar Item" in both the allowed and default sets.
The toolbar item has a height of 32 and a max width of 10000 so it can stretch to fill the title bar.
In my toolbar delegate, in toolbarWillAddItem:, I instantiate the view controller from the nib and put its view into the item.
A text label that is effectively the new window title has its value bound to the window's title.
To match the spacing in Xcode's title bar, use a left and right margin of 1 pixel (zero will cut off the edges) and a top margin of 5.
window.titleVisibility = .hidden moves the toolbar into the title area.
How do you change the width of a button in a tool bar on Mac? I can change the width in interface builder but it only updates if the width is larger than the current size. If I try to make it smaller it doesn't change in tool bar.
Not sure if you found an answer yet, but I was recently looking to do this as well for a popup button. The answer is to create the button outside the toolbar first. Then once you create it you can drag it onto the toolbar area and it will be added as a toolbar item.
For example, I created a popup button on my main window and set it to the width that I wanted. Then I opened the toolbar section and dragged that button onto it... and it worked.
Good luck.
I'm trying to make my first Cocoa app (previously I was making iOS apps) and what I wish to do for my custom view is make it's title clickable with indicator (accessory) triangle facing down.
Clicking the title would open a popup/menu with my items.
How is that doneable in Cocoa?
Rdelmar's answer is probably the easiest way to go, but may not do exactly what you might want to do (which is replace the actual title with a pop up item, instead of having a popup button under the title in the toolbar area). With respect to functionality your application will probably work just as well using the toolbar.
If, however, you truly want to replace the actual title, the means of going about this would be to set the NSWindow title text to #"" to hide it, and redraw it by sticking in your own view.
[[[theWindow contentView] superview] addSubview:theSubview];
This basically tells the superview of the main content view to add another subview (direct "translation" from the code), and you'll have to tinker with the frame of this new subview to have it be positioned where the title should be positioned (as now it's free to be placed anywhere in the window frame, including on top of the title bar, as opposed to simply inside the content view).
theSubview can be your popup button, or whatever you want, and you'll also probably have to custom draw the popup button to match the original drawing of the window title.
You can do this by adding a toolbar to your window in IB. Once, you add the toolbar, you can double click on it to open the customizer view of it. Drag a popup button into the Allowable Toolbar Items area and after it is inserted there you can drag it into the bottom area which shows the layout of the toolbar -- you can also drag out any of the default items there that you don't want.
If i create WinForms / Qt / Gtk application i use so called "layout managers" (or "geometry managers") to automatically layout my UI according to text inside widgets and my instructions. For example, if i layout a window with big edit field and 2 buttons below it aligned right i write following code "Create a window with vertical layout manager. Add edit widget as first item and horizontal layout manager as second item. For horizontal layout manager add spacer as first item, button as second and button as third". My window will be automatically resized according to button labels and edit field size. Also, if i resize my window all items will be resized automatically.
Is it something like layout managers for OSX? I have found that NSView can be added into hierarchy, but i can't find any ways to instruct parent NSView something like "arrange child NSViews vertically".
You should read about Cocoa Auto Layout, new in OS X 10.7.
I have to implement a custom toolbar for my application, where a button will be placed on the side of exit, maximize and minimize buttons.
I tried to work with the toolbar element on XCode, but it always put elements below these buttons and not on the side.
App Store application implement this feature, like you can see in this image.
One solution is to start with this open source code (https://github.com/indragiek/INAppStoreWindow) to give you the correct title bar style, and then position buttons in the titlebar.
