   I. Create a proof-of-concept for Tk running directly on the Wayland display protocol

See TkGS for an older attempt at reworking the underpinnings of Tk.
See this source code for how to actually get a working drawing surface with Wayland. Pay particular attention to the snippet including wl_egl_window_create and eglCreateWindowSurface…

Comments & Discussion

PYK 2014-09-11: Would Tk perhaps get more mileage out of targeting SDL?

DKF 2014-09-11: Only if SDL has been ported to run on top of Wayland. (Googling indicates that experimental support is in SDL 2.0.2, but I don't know what that implies…)

chw 2017-01-11: The trunk of the fossil repository of http://www.androwish.org now provides Wayland support in undroidwish based on a modified version of SDL 2.0.5, which was tested successfully on the GNOME based Fedora 25 workstation. A self contained experimental undroidwish for x86_64 Linux with the Wayland and X11 drivers can be downloaded from http://www.ch-werner.de/AndroWish/undroidwish-wayland-linux64
