How to disable iconified button in JFrame Window ?
something like setResizable, but for minimize button
At First, you can use the method setUndecorated(boolean). It may disable the title bar and the border.
In the end, you will create the icon label and close button at your frame top or the others position.
But this way will lose the border look and feel for the frame. If you choose this way, you must create a lot of code.
In fact, If you could not use JNI, this way may be the only.
You could use a JDialog, which natively does not have a minimize button.
In fact, the minimize, close and maximize/un-maximize buttons are drawn by the Operating System itself. This means you can't really disable them within Java.
That's why my suggestion is to use a JDialog.

I need to use StageStyle utility because I need to hide window icon in taskbar. However, I also need to hide and close button. How to do it? Or maybe there is another solution - no window title bar + no icon in task bar?
This answer is more of a general one: The core problem is that JavaFX doesn't allow you to hide the taskbar icon. So I guess you really don't want to use a Utility StageStyle, but rather are forced to.
Swing allows you to hide the taskbar icon. So the hackaround is simple: Use JavaFX inside a Swing JFrame and hide it from the taskbar.
You can take a look at the widget code in the answer here as an example.
I created a JFrame and in the top right corner I have 3 buttons (minimize, maximize, close). How do I get the size of these buttons? I want to place a new button just to the left of the minimize button in the title bar but I need to know how much space these existing buttons take up so that I don't place my button on top of them. ie If you open a recent version of the Chrome browser you'll see a button beside the minimize button in the browser window. I want to do the same sort of thing in my Java application.
What your describing is very advanced.
An alternative route would be to use:
setUndecorated(true);
Then create your own window decorations. This way everything matches and you can add all of the button that you want.
I have a custom JFrame. On the title bar I have an icon in the top left, a title, and then the standard minimize, maximize, and close buttons on the right.
When I click the icon in the title bar I get the standard options: Restore, Move, Size, Minimize, Maximize, Close.
How can I add my own menu option here? I'd like to add and "Always On Top" option here.
Additionally I'd like to add a button next to the max,min,close buttons on the title bar to allow uses to toggle the "Always On Top" state of the JFrame.
You could create your own customized Components. To do that, create a new class which extends JMenuBar for example and override the methods which fit your needs. Very often, for example, one wants to override paintComponent(Graphics).
That is not what you want, 'though. Customizing the JMenuBar wont work as you expect it to. The "JMenuBar" is another bar below the title bar. I am Mac user, but as far as my knowledge goes, it is not possible to customize the title bar, because that isn't handled by the JVM. The only thing that is modifiable without using native code is the Icon in the top left.
For further information on that, look at this question and the best answer there. This will help you a lot.
Your problem (adding a button at the top for toggling the alwaysOnTop status) is best solved by creating normal instances of a JMenuBar, a JMenu and a JMenuItem.
To then add that MenuBar to your Frame, use JFrame.setJMenuBar(JMenuBar). See also How to use Menus.
I hope this helps!
I want to add the new button with an icon of a question mark to the left of buttons "maximize", "hide" and "close". how to make it (like in a pic)?
You need to create a custom RootPane/TitleBar.
This means you need to set your JFrame to undecorated and then set your custom instance of what extends RootPane to your JFrame
It is hard to change native Title bar, because it is originating from the operating system. But you can remove native Title-bar setUndecorated(true); and create your own Title-bar , See simple tutorial here

I am testing some code using JWindow and that hide jframe, so I have to create minimize, maximize and close buttons for user friendly. How can I set state to frame when click on created buttons.
See JFrame#setState. You can do:
myFrame.setState(Frame.ICONIFIED)
As the implementation of a listener of the buttons.
