</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.

Calling this function allows you to override the default behaviour

270

when a Custom widget is found in an interface. This could be used by

271

a language binding to call some other function, or to limit what

272

functions can be called to create custom widgets.</p><p>
