    -- t'GI.Gtk.Objects.SizeGroup.SizeGroup' provides a mechanism for grouping a number of widgets
    -- together so they all request the same amount of space.  This is
    -- typically useful when you want a column of widgets to have the same
    -- size, but you can’t use a t'GI.Gtk.Objects.Grid.Grid' widget.
    --
    -- In detail, the size requested for each widget in a t'GI.Gtk.Objects.SizeGroup.SizeGroup' is
    -- the maximum of the sizes that would have been requested for each
    -- widget in the size group if they were not in the size group. The mode
    -- of the size group (see 'GI.Gtk.Objects.SizeGroup.sizeGroupSetMode') determines whether
    -- this applies to the horizontal size, the vertical size, or both sizes.
    --
    -- Note that size groups only affect the amount of space requested, not
    -- the size that the widgets finally receive. If you want the widgets in
    -- a t'GI.Gtk.Objects.SizeGroup.SizeGroup' to actually be the same size, you need to pack them in
    -- such a way that they get the size they request and not more. For
    -- example, if you are packing your widgets into a table, you would not
    -- include the 'GI.Gtk.Flags.AttachOptionsFill' flag.
    --
    -- t'GI.Gtk.Objects.SizeGroup.SizeGroup' objects are referenced by each widget in the size group,
    -- so once you have added all widgets to a t'GI.Gtk.Objects.SizeGroup.SizeGroup', you can drop
    -- the initial reference to the size group with 'GI.GObject.Objects.Object.objectUnref'. If the
    -- widgets in the size group are subsequently destroyed, then they will
    -- be removed from the size group and drop their references on the size
    -- group; when all widgets have been removed, the size group will be
    -- freed.
    --
    -- Widgets can be part of multiple size groups; GTK+ will compute the
    -- horizontal size of a widget from the horizontal requisition of all
    -- widgets that can be reached from the widget by a chain of size groups
    -- of type 'GI.Gtk.Enums.SizeGroupModeHorizontal' or 'GI.Gtk.Enums.SizeGroupModeBoth', and the
    -- vertical size from the vertical requisition of all widgets that can be
    -- reached from the widget by a chain of size groups of type
    -- 'GI.Gtk.Enums.SizeGroupModeVertical' or 'GI.Gtk.Enums.SizeGroupModeBoth'.
    --
    -- Note that only non-contextual sizes of every widget are ever consulted
    -- by size groups (since size groups have no knowledge of what size a widget
    -- will be allocated in one dimension, it cannot derive how much height
    -- a widget will receive for a given width). When grouping widgets that
    -- trade height for width in mode 'GI.Gtk.Enums.SizeGroupModeVertical' or 'GI.Gtk.Enums.SizeGroupModeBoth':
    -- the height for the minimum width will be the requested height for all
    -- widgets in the group. The same is of course true when horizontally grouping
    -- width for height widgets.
    --
    -- Widgets that trade height-for-width should set a reasonably large minimum width
    -- by way of [Label:widthChars]("GI.Gtk.Objects.Label#g:attr:widthChars") for instance. Widgets with static sizes as well
    -- as widgets that grow (such as ellipsizing text) need no such considerations.
    --
    -- = GtkSizeGroup as GtkBuildable
    --
    -- Size groups can be specified in a UI definition by placing an @\<object>@
    -- element with @class=\"GtkSizeGroup\"@ somewhere in the UI definition. The
    -- widgets that belong to the size group are specified by a @\<widgets>@ element
    -- that may contain multiple @\<widget>@ elements, one for each member of the
    -- size group. The ”name” attribute gives the id of the widget.
    --
    -- An example of a UI definition fragment with GtkSizeGroup:
    --
    --
    -- === /xml code/
    -- >
    -- ><object class="GtkSizeGroup">
    -- >  <property name="mode">GTK_SIZE_GROUP_HORIZONTAL</property>
    -- >  <widgets>
    -- >    <widget name="radio1"/>
    -- >    <widget name="radio2"/>
