<p>
|
||
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
|
||
<code class="literal">GDK_BACKEND=broadway</code>. Then you can make
|
||
your application appear in a web browser by pointing it at
|
||
<code class="literal">http://127.0.0.1:8080</code>. Note that you need
|
||
to enable web sockets in your web browser.
|
||
</p>
|
||
<p>
|
||
You can choose a different port from the default 8080 by setting
|
||
the <code class="envar">BROADWAY_DISPLAY</code> environment variable to the
|
||
port that you want to use.
|
||
</p>
|
||
<p>
|
||
It is also possible to use multiple GTK+ applications in the same
|
||
web browser window, by using the Broadway server,
|
||
<span class="command"><strong>broadwayd</strong></span>, that ships with GTK+.
|
||
To use broadwayd, start it like this:
|
||
</p>
|
||
<pre class="programlisting">
|
||
broadwayd :5
|
||
</pre>
|
||
<p>
|
||
Then point your web browser at <code class="literal">http://127.0.0.1:8085</code>.
|
||
Start your applications like this:
|
||
</p>
|
||
<pre class="programlisting">
|
||
GDK_BACKEND=broadway BROADWAY_DISPLAY=:5 gtk3-demo
|
||
</pre>
|
||
<p>
|
||
</p>
|
||
<div class="refsect2">
|
||
<a name="broadway-envar"></a><h3>Broadway-specific environment variables</h3>
|
||
</div>
|
||
<p><b><code class="envar">BROADWAY_DISPLAY</code>. </b>
|
||
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:
|
||
</p>
|
||
<pre class="programlisting">
|
||
<em class="replaceable"><code>port</code></em> = 8080 + <em class="replaceable"><code>display</code></em>
|

</pre>
