GTK+ Developer Alexander Larsson gtk4-broadwayd 1 User Commands gtk4-broadwayd Broadway display server gtk4-broadwayd --port PORT --address ADDRESS --unixsocket ADDRESS :DISPLAY gtk4-broadwayd is a display server for the Broadway GDK backend. It allows multiple GTK+ applications to display their windows in the same web browser, by connecting to gtk4-broadwayd. When using gtk4-broadwayd, specify the display number to use, prefixed with a colon, similar to X. The default display number is 0. gtk4-broadwayd :5 Then point your web browser at http://127.0.0.1:8085. Start your applications like this: GDK_BACKEND=broadway BROADWAY_DISPLAY=:5 gtk3-demo You can add password protection for your session by creating a file in $XDG_CONFIG_HOME/broadway.passwd or $HOME/.config/broadway.passwd with a crypt(3) style password hash. A simple way to generate it is with openssl: openssl passwd -1 > ~/.config/broadway.passwd --port Use PORT as the HTTP port, instead of the default 8080 + (DISPLAY - 1). --address Use ADDRESS as the HTTP address, instead of the default http://127.0.0.1:PORT. --unixsocket Use ADDRESS as the unix domain socket address. This option overrides --address and --port. It is available only on Unix-like systems.
