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
|
|
<literal>GDK_BACKEND=broadway</literal>. Then you can make
|
|
your application appear in a web browser by pointing it at
|
|
<literal>http://127.0.0.1:8080</literal>. 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 <envar>BROADWAY_DISPLAY</envar> 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,
|
|
<command>broadwayd</command>, that ships with GTK+.
|
|
To use broadwayd, start it like this:
|
|
<programlisting>
|
|
broadwayd :5
|
|
</programlisting>
|
|
Then point your web browser at <literal>http://127.0.0.1:8085</literal>.
|
|
Start your applications like this:
|
|
<programlisting>
|
|
GDK_BACKEND=broadway BROADWAY_DISPLAY=:5 gtk3-demo
|
|
</programlisting>
|
|

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:
|
|
<programlisting>
|
|
<replaceable>port</replaceable> = 8080 + <replaceable>display</replaceable>
|
|
</programlisting>
