Wayland compositor delegating window management to Gtk layout. Written with help of wlroots.
"Gwayco" stands for "Gtk Wayland compositor".
Development status: alpha.
This project aims to make creating Wayland managers simple. It consists of two components: the actual server (wlroots) and a Gtk app. The Gtk app displays a window that is drawn as a desktop and receives create/destroy events from other apps. For each foreign app window there is a "shadow" widget that can be placed in a Gtk layout. The server then configures app windows to mimick geometry of the shadow widget.
Making a tiling window manager is as simple as placing Gtk.Box in the root window.
If window manager is not present, the compositor is expected to position windows using some built-in default.
You can try it from existing X11 or Wayland session. Make sure you have wlroots and Gtk installed together with Python bindings.
From the project's directory run:
./compositor.py seat0 ./desktop.py
Make sure to use the correct "seat" which is seat0 for most people.
A window should appear, with the Glade layout as chosen by desktop.py.
Find the name of Wayland socket in the logs, which should be wayland-0 if you are running under X11 or wayland-1 if from inside other Wayland session.
Then try connecting some desktop apps to the server.
You may use the provided hello.py that accepts arguments and displays them as a label.
GDK_BACKEND=wayland WAYLAND_DISPLAY=wayland-0 ./hello.py one one one
GDK_BACKEND=wayland WAYLAND_DISPLAY=wayland-0 ./hello.py two two two
The new app window show should be added to a layout, making it a very simple tiling window manager.
