A 'GI.Gtk.Objects.Expander.Expander' allows the user to hide or show its child by clicking
on an expander triangle similar to the triangles used in a 'GI.Gtk.Objects.TreeView.TreeView'.

Normally you use an expander as you would use any other descendant
of 'GI.Gtk.Objects.Bin.Bin'; you create the child widget and use 'GI.Gtk.Objects.Container.containerAdd'
to add it to the expander. When the expander is toggled, it will take
care of showing and hiding the child automatically.

= Special Usage

There are situations in which you may prefer to show and hide the
expanded widget yourself, such as when you want to actually create
the widget at expansion time. In this case, create a 'GI.Gtk.Objects.Expander.Expander'
but do not add a child to it. The expander widget has an
'GI.Gtk.Objects.Expander.Expander':@/expanded/@ property which can be used to monitor
its expansion state. You should watch this property with a signal
connection as follows:


=== /C code/
>
>static void
>expander_callback (GObject    *object,
>                   GParamSpec *param_spec,

>

>  g_signal_connect (expander, "notify::expanded",
>                    G_CALLBACK (expander_callback), NULL);
>
>  // ...
>}


= GtkExpander as GtkBuildable

The GtkExpander implementation of the GtkBuildable interface supports
placing a child in the label position by specifying “label” as the
“type” attribute of a \<child> element. A normal content child can be
specified without specifying a \<child> type attribute.

An example of a UI definition fragment with GtkExpander:
>
><object class="GtkExpander">
>  <child type="label">
>    <object class="GtkLabel" id="expander-label"/>
>  </child>
>  <child>
>    <object class="GtkEntry" id="expander-content"/>
>  </child>
></object>


= CSS nodes


=== /plain code/
>
>expander
>├── title
>│   ├── arrow
>│   ╰── <label widget>
>╰── <child>


GtkExpander has three CSS nodes, the main node with the name expander,
a subnode with name title and node below it with name arrow. The arrow of an
expander that is showing its child gets the :checked pseudoclass added to it.
