I have begun to implement a StageStyle variation called TOOLKIT_DECORATED (better naming welcome).
It would be JavaFX's version of: https://docs.gtk.org/gtk4/class.HeaderBar.html The goal is to allow a Toolkit decorated window that accepts controls inside the decoration such as a "hamburger menu", tabs (like firefox) or anything else. On Linux it would depend on: https://docs.gtk.org/gdk3/method.Window.begin_move_drag.html That's because the Window Manager would block moving it within desktop constraints, unless using this function. It would auto-style (as modena does) buttons and other controls inside it. I don't promise I will ever finish this, because I do it for fun and I have no time for fun :) I know I have to do a feature proposal and discussion and It might not be accepted. Cheers -- Thiago.
