Paint.NET style ToolWindow

Question

Can anyone tell me how to make Paint.NET style ToolWindow(s)? Sorry I don't know if there is some kind of terminology to describe this better.

Currently my ToolWindows take focus whenever I click on a control inside of the ToolWindow or the ToolWindow itself. This means that if I click on the ToolBar or the MenuBar in the main form of my program that only bring the form into focus and doesn't actually click on the ToolBar / Menu. I don't want that.
