The 'GI.Gtk.Objects.TreeStore.TreeStore' object is a list model for use with a 'GI.Gtk.Objects.TreeView.TreeView'
widget.  It implements the 'GI.Gtk.Interfaces.TreeModel.TreeModel' interface, and consequentially,
can use all of the methods available there.  It also implements the
'GI.Gtk.Interfaces.TreeSortable.TreeSortable' interface so it can be sorted by the view.  Finally,
it also implements the tree
[drag and drop][gtk3-GtkTreeView-drag-and-drop]
interfaces.

= GtkTreeStore as GtkBuildable

The GtkTreeStore implementation of the 'GI.Gtk.Interfaces.Buildable.Buildable' interface allows
to specify the model columns with a \<columns> element that may contain
multiple \<column> elements, each specifying one model column. The “type”
attribute specifies the data type for the column.

An example of a UI Definition fragment for a tree store:
>
><object class="GtkTreeStore">
>  <columns>
>    <column type="gchararray"/>
>    <column type="gchararray"/>
>    <column type="gint"/>
>  </columns>
></object>
