I'd like add a button for changing window state to topmost to the built-in window buttons such as maximize, minimize, and close [please refer to this pic.]
However, I'm having hard time finding the way out as WPF seems not to provide such an API. I even thought using the icon next to the window title functioning as the button for topmost, but looks not feasible.
Is there anyway like using .dll or could I inherit the window class and add the button and corresponding event handler anyhow?
Thanks.
