Adding buttons to a Tool Window Title bar

Question

How Can I add another button on the Title Bar of the Tool Window next to the close window button?

For instance having an Auto Hide and Window Position buttons you see in visual studio Tool windows.

Answer 1

I'm not sure if it can be done more elegantly with pure C#, but normally I use a window with the border style set to none and make my own mock title bar using standard buttons that look like a normal Windows title bar. It's a bit hackey, but when I really need something like this it's the simplest approach.
