Using GTK+ with BroadwayUsing 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 gtk3-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
