Swing: Add help [?] button to window titlebar

Question

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)? enter image description here

I don't think it is possible in Swing. Not sure about other toolkits, but I doubt it. — MightyPork, Dec 05 '14 at 21:42
Welcome to what is probably amongst one of the most requested features for Swing. No, you can't do it. You "might" be able to use JNI/JNA solution, but that's a lot of work and you'd need to consider the need to provide cross platform support — MadProgrammer, Dec 05 '14 at 22:43

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

You can see an another way in Substance look-and-feel
