Broadway Gtk3 backend

GTK's X11 Backend Now Deprecated, Planned For Removal In GTK 5 HTML5 Broadway backends. Broadway was a nifty back-end for outputting to modern HTML5 for GTK apps within web browsers but ultimately not much use[1]

The GDK Broadway backend provides support for displaying GTK+ applications in a web browser, using HTML5 and web sockets.

To run your application in this way, select the Broadway backend by setting GDK_BACKEND=broadway. Then you can make your application appear in a web browser by pointing it at http://127.0.0.1:8080. Note that you need to enable web sockets in your web browser.

Broadway GDK backend allows multiple GTK+ applications to display their windows in the same web browser, by connecting to a Broadway display server.

Linux

• Broadway backend - Arch Linux Wiki

Ubuntu

In a terminal, run:

broadwayd

In another terminal, run:

GDK_BACKEND=broadway UBUNTU_MENUPROXY= LIBOVERLAY_SCROLLBAR=0 gramps

Finally, open you Web browser and go to:

 http://localhost:8080/

The UBUNTU_MENUPROXY= LIBOVERLAY_SCROLLBAR=0 is only useful if you use the global-menu and/or overlay-scrollbars. You have to disable them for Broadway, otherwise the program will segfault.

Please see the "broadwayd" manpage for more information.
