<title>Embedding distribution information</title>
</head>
<body>
<h2>Introduction</h2>
<p>This is the Embedding distribution of <a
href="http://www.mozilla.org/">Mozilla</a>. It serves as a reference
and smoketest distribution to demonstrate a typical subset of Mozilla
needed to embed it into another application. The distribution contains
sample applications for testing and development purposes.</p>
<p>Please note the phrase<i> typical subset</i>! If you want to use a different
subset then see the <a href="#cust">customizing the embedding distribution</a>
section below.</p>
<h2>Where can I find more information about embedding? </h2>

<h2>Contents </h2>
<p>The distribution contains, libraries, resources and chrome. All of this
is a subset of Mozilla, repackaged for embedding. The layout follows
the usual Mozilla directory, i.e. </p>
<ul>
<li>./ - Test applications, launch scripts and core libraries (xpcom,
nspr etc.)</li>
<li>./components/ - XPCOM components (network, graphics, layout,
content, etc.).</li>
<li>./chrome/ - chrome files. In embedding most of the chrome has
been re-packaged into a single embed.jar file to make it more manageable.</li>
<li>./res/ - miscellaneous rendering and parser files.</li>
<li>./defaults/ - default preference settings</li>
</ul>
<h3>Unix</h3>
<h4>TestGtkEmbed</h4>
<p>A simple browser application built using the GTK+ Browser Widget.</p>
<h4>GTK+ Browser Widget</h4>
<p>A GTK+ widget for embedding Mozilla into GTK+/GNOME applications such as
<a href="http://galeon.sourceforge.net/">Galeon</a>. More information
about the widget may be found here <a
href="http://www.mozilla.org/unix/gtk-embedding.html">http://www.mozilla.org/unix/gtk-embedding.html</a>.
</p>
<h3>Windows</h3>
<h4>MFCEmbed</h4>
<p>A complete browser application written in MFC and the Gecko embedding APIs.
This application demonstrates and exercises the functionality necessary
to put together a fully featured browser using Gecko.</p>
<h4>Mozilla ActiveX Control</h4>
<p>An ActiveX browser control built with the embedding APIs. You may use the
control to embed a browser inside applications written in VB, Delphi
etc. More information about the control including installation instructions
may be found at <a href="http://www.iol.ie/%7Elocka/mozilla/mozilla.htm">http://www.iol.ie/~locka/mozilla/mozilla.htm</a>.
</p>
<h3>Macintosh </h3>
<p>PPEmbed is built as part of the standard Mac embedding build. Work on <a
href="http://www.mozilla.org/ports/fizzilla/Mach.html">Fizilla Mach</a>
may also yield a Mac embedding distribution in the future. </p>
<h2>Installation and Usage </h2>
<h3>Unix</h3>
<ol>
<li>Untar the embedding distribution into an empty directory of your
choice.</li>
<li>From the command-line, cd into the directory and type
'./run-mozilla.sh ./TestGtkEmbed'</li>
</ol>
<h3>Windows </h3>
<ol>
<li>Unzip the embedding distribution into an empty directory of your
choice.</li>
<li>Double-click on mfcembed.exe</li>
</ol>
<h2><a name="cust">Customizing the embedding distribution</a></h2>
<p>The embedding distribution is produced by first building the full Mozilla
source and cherry picking files and chrome into a separate embedding
directory. Basically the steps are:</p>
<ol>
<li>Build Mozilla as usual</li>
<li>cd mozilla/embedding/config</li>
<li>make</li>
</ol>
<p>The embedding distribution will appear in mozilla/dist/Embed.</p>
<p>The build process works by reading a file called basebrowser-win (or
basebrowser-unix, basebrowser-mac-macho etc.) and copying the listed files
from mozilla/dist/bin into mozilla/dist/Embed. It then reads a file called
embed-jar.mn and repackages the specified chrome files and directories
into a single embed.jar.<br>
</p>
<p>This process can be customized in one of two ways:<br>
</p>
<ol>
<li>Edit basebrowser-foo (where foo = win, unix etc.) and remove/add the
items you require</li>
<li>Create a new file called client-foo and add the items you require.
This file is detected by the build process and will be run <i>after</i> the
contents of basebrowser-foo have been copied.</li>
</ol>
The latter is the best probably approach to take since the embedder can
maintain these files without modifying ones in Mozilla<i></i>. The client-foo
file allows embedders to specify files to be added or removed from the
default embedding distribution. A minus sign in front of a filename
deletes that file.
<p>For example if you wanted a distribution containing extra character converters,
but not the ActiveX control and not XMLExtras you might define a client-win
like this:</p>
<pre>[Embed]<br>components\ucvja.dll<br>components\ucvko.dll<br>components\ucvcn.dll<br>components\ucvtw.dll<br>components\ucvtw2.dll<br>components\ucvibm.dll<br>-mozctl.dll<br>-mozctlx.dll<br>-components\xmlextras.dll<br>-components\xmlextras.xpt<br></pre>
