    -- Uses constraints to describe relations between widgets.
    --
    -- @GtkConstraintLayout@ is a layout manager that uses relations between
    -- widget attributes, expressed via t'GI.Gtk.Objects.Constraint.Constraint' instances, to
    -- measure and allocate widgets.
    --
    -- === How do constraints work
    --
    -- Constraints are objects defining the relationship between attributes
    -- of a widget; you can read the description of the t'GI.Gtk.Objects.Constraint.Constraint'
    -- class to have a more in depth definition.
    --
    -- By taking multiple constraints and applying them to the children of
    -- a widget using @GtkConstraintLayout@, it\'s possible to describe
    -- complex layout policies; each constraint applied to a child or to the parent
    -- widgets contributes to the full description of the layout, in terms of
    -- parameters for resolving the value of each attribute.
    --
    -- It is important to note that a layout is defined by the totality of
    -- constraints; removing a child, or a constraint, from an existing layout
    -- without changing the remaining constraints may result in an unstable
    -- or unsolvable layout.
    --
    -- Constraints have an implicit \"reading order\"; you should start describing
    -- each edge of each child, as well as their relationship with the parent
    -- container, from the top left (or top right, in RTL languages), horizontally
    -- first, and then vertically.
    --
    -- A constraint-based layout with too few constraints can become \"unstable\",
    -- that is: have more than one solution. The behavior of an unstable layout
    -- is undefined.
    --
    -- A constraint-based layout with conflicting constraints may be unsolvable,
    -- and lead to an unstable layout. You can use the [Constraint:strength]("GI.Gtk.Objects.Constraint#g:attr:strength")
    -- property of t'GI.Gtk.Objects.Constraint.Constraint' to \"nudge\" the layout towards a solution.
    --
    -- === GtkConstraintLayout as GtkBuildable
    --
    -- @GtkConstraintLayout@ implements the t'GI.Gtk.Interfaces.Buildable.Buildable' interface and
    -- has a custom \"constraints\" element which allows describing constraints in
    -- a t'GI.Gtk.Objects.Builder.Builder' UI file.
    --
    -- An example of a UI definition fragment specifying a constraint:
    --
    --
    -- === /xml code/
    -- >  <object class="GtkConstraintLayout">
    -- >    <constraints>
    -- >      <constraint target="button" target-attribute="start"
    -- >                  relation="eq"
    -- >                  source="super" source-attribute="start"
    -- >                  constant="12"
    -- >                  strength="required" />
    -- >      <constraint target="button" target-attribute="width"
    -- >                  relation="ge"
    -- >                  constant="250"
    -- >                  strength="strong" />
    -- >    </constraints>
    -- >  </object>
    --
    --
    -- The definition above will add two constraints to the GtkConstraintLayout:
    --
    -- * a required constraint between the leading edge of \"button\" and
    --   the leading edge of the widget using the constraint layout, plus
    --   12 pixels
    -- * a strong, constant constraint making the width of \"button\" greater
    --   than, or equal to 250 pixels
    --
    --
    -- The \"target\" and \"target-attribute\" attributes are required.
    --
    -- The \"source\" and \"source-attribute\" attributes of the \"constraint\"
    -- element are optional; if they are not specified, the constraint is
    -- assumed to be a constant.
    --
    -- The \"relation\" attribute is optional; if not specified, the constraint
    -- is assumed to be an equality.
    --
    -- The \"strength\" attribute is optional; if not specified, the constraint
    -- is assumed to be required.
    --
    -- The \"source\" and \"target\" attributes can be set to \"super\" to indicate
    -- that the constraint target is the widget using the GtkConstraintLayout.
    --
    -- There can be \"constant\" and \"multiplier\" attributes.
    --
    -- Additionally, the \"constraints\" element can also contain a description
    -- of the @GtkConstraintGuides@ used by the layout:
    --
    --
    -- === /xml code/
    -- >  <constraints>
    -- >    <guide min-width="100" max-width="500" name="hspace"/>
    -- >    <guide min-height="64" nat-height="128" name="vspace" strength="strong"/>
    -- >  </constraints>
    --
    --
    -- The \"guide\" element has the following optional attributes:
    --
    -- * \"min-width\", \"nat-width\", and \"max-width\", describe the minimum,
    --   natural, and maximum width of the guide, respectively
    -- * \"min-height\", \"nat-height\", and \"max-height\", describe the minimum,
    --   natural, and maximum height of the guide, respectively
    -- * \"strength\" describes the strength of the constraint on the natural
    --   size of the guide; if not specified, the constraint is assumed to
    --   have a medium strength
    -- * \"name\" describes a name for the guide, useful when debugging
    --
    --
    -- === Using the Visual Format Language
    --
    -- Complex constraints can be described using a compact syntax called VFL,
    -- or *Visual Format Language*.
    --
    -- The Visual Format Language describes all the constraints on a row or
    -- column, typically starting from the leading edge towards the trailing
    -- one. Each element of the layout is composed by \"views\", which identify
    -- a t'GI.Gtk.Interfaces.ConstraintTarget.ConstraintTarget'.
    --
    -- For instance:
    --
    --
    --
    -- >  [button]-[textField]
    --
    --
    -- Describes a constraint that binds the trailing edge of \"button\" to the
    -- leading edge of \"textField\", leaving a default space between the two.
    --
    -- Using VFL is also possible to specify predicates that describe constraints
    -- on attributes like width and height:
    --
    --
    --
    -- >  // Width must be greater than, or equal to 50
    -- >  [button(>=50)]
    -- >
    -- >  // Width of button1 must be equal to width of button2
    -- >  [button1(==button2)]
    --
    --
    -- The default orientation for a VFL description is horizontal, unless
    -- otherwise specified:
    --
    --
    --
    -- >  // horizontal orientation, default attribute: width
    -- >  H:[button(>=150)]
    -- >
    -- >  // vertical orientation, default attribute: height
    -- >  V:[button1(==button2)]
    --
    --
    -- It\'s also possible to specify multiple predicates, as well as their
    -- strength:
    --
    --
    --
    -- >  // minimum width of button must be 150
    -- >  // natural width of button can be 250
    -- >  [button(>=150@required, ==250@medium)]
    --
    --
    -- Finally, it\'s also possible to use simple arithmetic operators:
    --
    --
    --
    -- >  // width of button1 must be equal to width of button2
    -- >  // divided by 2 plus 12
    -- >  [button1(button2 / 2 + 12)]
    --
