Using GTK with Broadway — HTML-specific aspects of using GTK
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_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
