</pre></div><div class="refsect1" lang="en"><a name="id294170"></a><h2>Description</h2><p>
This object represents an `instantiation' of an XML interface description.
When one of these objects is created, the XML file is read, and the
interface is created. The GladeXML object then provides an interface for
accessing the widgets in the interface by the names assigned to them
inside the XML description.
</p><p>
The GladeXML object can also be used to connect handlers to the named
signals in the description. Libglade also provides an interface by which
it can look up the signal handler names in the program's symbol table and
automatically connect as many handlers up as it can that way.

This function is a variation of glade_xml_signal_connect. It uses
gmodule's introspective features (by openning the module <tt class="literal">NULL</tt>) to
look at the application's symbol table. From here it tries to match
the signal handler names given in the interface description with
symbols in the application and connects the signals.

supported on the platform.</p><p>

This function is similar to glade_xml_signal_connect, except that it
allows you to give an arbitrary function that will be used for actually
connecting the signals. This is mainly useful for writers of interpreted
language bindings, or applications where you need more control over the
signal connection process.</p><p>

This function is similar to glade_xml_signal_connect_full, except that it
will try to connect all signals in the interface, not just a single
named handler. It can be thought of the interpeted language binding
version of glade_xml_signal_autoconnect, except that it does not
require gmodule to function correctly.</p><p>

when a Custom widget is found in an interface. This could be used by
a language binding to call some other function, or to limit what
