Using GTK with Broadway
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.
You can choose a different port from the default 8080 by setting
the BROADWAY_DISPLAY environment variable to the port that you
want to use.
It is also possible to use multiple GTK applications in the same
web browser window, by using the Broadway server, broadwayd, that
ships with GTK. To use broadwayd, start it like this:
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 gtk4-demo
Broadway-specific environment variables
BROADWAY_DISPLAY
Specifies the Broadway display number. The default display is 0.
The display number determines the port to use when connecting
to a Broadway application via the following formula:
port = 8080 + display
