A <a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a>
is an auxiliary object that reads textual descriptions of a user interface and
instantiates the described objects. To pass a description to a
<a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a>, call
<code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--add-from-file" title="gtk.Builder.add_from_file">add_from_file</a></code>() or
<code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--add-from-string" title="gtk.Builder.add_from_string">add_from_string</a></code>().
These methods can be called multiple times; the builder merges the content of all descriptions.
</p><p>
A <a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a>
holds a reference to all objects that it has constructed and drops these references
when it is finalized. This finalization can cause the destruction of non-widget objects
or widgets which are not contained in a toplevel window. For toplevel windows constructed
by a builder, it is the responsibility of the user to call
<code class="methodname"><a class="link" href="class-gtkwidget.html#method-gtkwidget--destroy" title="gtk.Widget.destroy">gtk.Widget.destroy</a></code>()
to get rid of them and all the widgets they contain.
</p><p>
The methods <code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--get-object" title="gtk.Builder.get_object">get_object</a></code>()
and <code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--get-objects" title="gtk.Builder.get_objects">get_objects</a></code>()
can be used to access the widgets in the interface by the names assigned to them inside the UI description.
Toplevel windows returned by these methods will stay around until the user explicitly
destroys them with <code class="methodname"><a class="link" href="class-gtkwidget.html#method-gtkwidget--destroy" title="gtk.Widget.destroy">gtk.Widget.destroy</a></code>().
Other widgets will either be part of a larger hierarchy constructed by the builder (in which case you
should not have to worry about their lifecycle), or without a parent, in which case they have to be added
to some container to make use of them.
</p><p>
The methods <code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--connect-signals" title="gtk.Builder.connect_signals">connect_signals</a></code>()
and variants thereof can be used to connect handlers to the named signals in the description.
</p><div class="refsect2" title="gtk.Builder UI definition"><a name="gtkbuilder-ui-definition"></a><h3>gtk.Builder UI definition</h3><p>
<a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a> parses textual
descriptions of user interfaces which are specified in an XML format which
can be roughly described by the DTD below. We refer to these descriptions as GtkBuilder UI definitions
or just UI definitions if the context is clear. Do not confuse GtkBuilder UI Definitions with
GtkUIManager UI Definitions, which are more limited in scope.

The toplevel element is <interface>. It optionally takes a "domain" attribute,
which will make the builder look for translated strings using dgettext() in the domain
specified. This can also be done by calling
<code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--set-translation-domain" title="gtk.Builder.set_translation_domain">set_translation_domain</a></code>()
on the builder. Objects are described by <object> elements, which can contain <property>
elements to set properties, <signal> elements which connect signals to handlers, and <child>
elements, which describe child objects (most often widgets inside a container, but also e.g. actions
in an action group, or columns in a tree model). A <child> element contains an <object>
element which describes the child object. The target toolkit version(s) are described by <requires>
elements, the "lib" attribute specifies the widget library in question (currently the only supported value
is "gtk+") and the "version" attribute specifies the target version in the form "<major>.<minor>".
The builder will error out if the version requirements are not met.
</p><p>
Typically, the specific kind of object represented by an <object> element is specified by the
"class" attribute. If the type has not been loaded yet, GTK+ tries to find the _get_type() from the
class name by applying heuristics. This works in most cases, but if necessary, it is possible to specify
the name of the _get_type() explictly with the "type-func" attribute. As a special case,
<a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a> allows to use an object that
has been constructed by a <a class="link" href="class-gtkuimanager.html" title="gtk.UIManager"><code class="classname">gtk.UIManager</code></a>
in another part of the UI definition by specifying the id of the
<a class="link" href="class-gtkuimanager.html" title="gtk.UIManager"><code class="classname">gtk.UIManager</code></a> in the "constructor" attribute
and the name of the object in the "id" attribute.
</p><p>
Objects must be given a name with the "id" attribute, which allows the application to retrieve them from
the builder with <code class="methodname"><a class="link" href="class-gtkbuilder.html#method-gtkbuilder--get-object" title="gtk.Builder.get_object">get_object</a></code>().
An id is also necessary to use the object as property value in other parts of the UI definition.
</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3>
Prior to GTK+ 2.20, <a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a>
was setting the "name" property of constructed widgets to the "id" attribute. In GTK+ 2.20 or newer, you
have to use <a class="link" href="class-gtkbuildable.html#method-gtkbuildable--set-name" title="gtk.Buildable.set_name"><code class="methodname">gtk.Buildable.get_name</code></a>()
instead of <a class="link" href="class-gtkwidget.html#method-gtkwidget--get-name" title="gtk.Widget.get_name"><code class="methodname">gtk.Widget.get_name</code></a>()
to obtain the "id", or set the "name" property in your UI definition.
</div><p>
Setting properties of objects is pretty straightforward with the <property>element: the "name"
attribute specifies the name of the property, and the content of the element specifies the value. If the
"translatable" attribute is set to a true value, GTK+ uses gettext() (or dgettext() if the builder has
a translation domain set) to find a translation for the value. This happens before the value is parsed,
so it can be used for properties of any type, but it is probably most useful for string properties.
It is also possible to specify a context to disambiguate short strings, and comments which may
help the translators.
</p><p>
GtkBuilder can parse textual representations for the most common property types: characters, strings,
integers, floating-point numbers, booleans (strings like "TRUE", "t", "yes", "y", "1" are interpreted as
<code class="literal">True</code>, strings like "FALSE, "f", "no", "n", "0" are interpreted as <code class="literal">False</code>),
enumerations (can be specified by their name, nick or integer value), flags (can be specified by their
name, nick, integer value, optionally combined with "|", e.g. "gtk.VISIBLE|gtk.REALIZED")
and colors (in a format understood by <a class="link" href="class-gdkcolor.html#function-gdk--color-parse" title="gtk.gdk.color_parse"><code class="methodname">gtk.gdk.color_parse</code></a>()).
Objects can be referred to by their name.
Pixbufs can be specified as a filename of an image file to load. In general, GtkBuilder allows
forward references to objects — an object doesn't have to be constructed before it can be referred to.
The exception to this rule is that an object has to be constructed before it can be used as the value
of a construct-only property.
</p><p>
Signal handlers are set up with the <signal> element. The "name" attribute specifies the name
of the signal, and the "handler" attribute specifies the function to connect to the signal. By default,
GTK+ tries to find the handler using g_module_symbol(). The remaining attributes, "after", "swapped"
and "object", have the same meaning as the corresponding parameters of the g_signal_connect_object() or
g_signal_connect_data() functions. A "last_modification_time" attribute is also allowed, but it does not
have a meaning to the builder.
</p><p>
Sometimes it is necessary to refer to widgets which have implicitly been constructed by GTK+ as part of
a composite widget, to set properties on them or to add further children (e.g. the vbox of a
<a class="link" href="class-gtkdialog.html" title="gtk.Dialog"><code class="classname">gtk.Dialog</code></a>).
This can be achieved by setting the "internal-child" propery of the <child> element to a true value.
Note that <a class="link" href="class-gtkbuilder.html" title="gtk.Builder"><code class="classname">gtk.Builder</code></a>
still requires an <object> element for the internal child, even if it has already been constructed.
</p><p>
A number of widgets have different places where a child can be added (e.g. tabs vs. page content in
notebooks). This can be reflected in a UI definition by specifying the "type" attribute on a
<child> The possible values for the "type" attribute are described in the sections describing
the widget-specific portions of UI definitions.

Beyond this general structure, several object classes define their own XML DTD
fragments for filling in the ANY placeholders in the DTD above. Note that a
custom element in a <child> element gets parsed by the custom tag handler of
the parent object, while a custom element in an <object> element gets parsed
by the custom tag handler of the object.
</p><p>
These XML fragments are explained in the documentation of their respective objects in the
GTK+ Reference Manual.

The <code class="methodname">connect_signals</code>() method uses Python's introspective
features to look at the keys (if object is a mapping) or attributes (if object is an instance)
and tries to match them with the signal handler names given in the interface description.
The callbacks referenced by each matched key or attribute are connected to their matching signals.
</p><p>
For each of handlers that cannot be found, a <code class="classname">RuntimeWarning</code>
is issued. Also, if there is at least one such missing handler,
<code class="methodname">connect_signals</code> will return a list of their names,
else return value is None.
