I need to disable/remove the minimize and maximize buttons in window form. I don't know how to access the form from my OpenTK.GameWindow, any help is appreciated.
This is deceptively easy:
WindowBorder = WindowBorder.Hidden;
GameWindow does not use WinForms, it p/invokes the underlying platform directly (performance!)
Edit: or do you mean keep the close button but remove minimize/maximize? The closest to this is:
WindowBorder = WindowBorder.Fixed;
