How to write and install a catalog for a python widget library

<title>Introduction</title>
<para>
Glade supports loading widgets coded in python by linking and running the python
interpreter from the gladepython catalog plugin.
</para>
<para>
So in order for glade to include your python gtk widgets you will have to:
<varlistentry><listitem>
a) specify gladepython support code as your plugin library.
</listitem></varlistentry>
<varlistentry><listitem>
b) set glade_python_init as you init function.
</listitem></varlistentry>
<varlistentry><listitem>
c) make sure your catalog name is the same as your python import library since
glade_python_init() will use this name to import your widgets into the
interpreter.
</listitem></varlistentry>
pythonplugin.xml
<programlisting>
<![CDATA[
<glade-catalog name="pythonplugin" library="gladepython"
domain="glade-3" depends="gtk+">
<init-function>glade_python_init</init-function>
<glade-widget-classes>
<glade-widget-class title="MyPythonBox" name="MyPythonBox" generic-name="mypythonbox"/>
</glade-widget-classes>
<glade-widget-group name="python" title="Python">
<glade-widget-class-ref name="MyPythonBox"/>
</glade-widget-group>
</glade-catalog>]]>
</programlisting>
</para>
<para>
Glade's python interpreter will look up for your widgets in the same
places it looks
for regular catalogs plugins, that is $GLADE_ENV_MODULE_PATH
environment variable
and `pkg-config --variable=moduledir gladeui-2.0`
So the easiest thing would be to make a symlink in one of those directory, just
do not forget that the name should be the one specified in your catalog name.
