    -- Groups widgets together so they all request the same size.
    --
    -- 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' or t'GI.Gtk.Objects.Box.Box'.
    --
    -- In detail, the size requested for each widget in a @GtkSizeGroup@ 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]'GI.Gtk.Objects.SizeGroup.sizeGroupSetMode' of the size group 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 @GtkSizeGroup@ 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. In
    -- particular it doesn\'t make a lot of sense to set
    -- [the expand flags]'GI.Gtk.Objects.Widget.widgetSetHexpand' on the widgets that
    -- are members of a size group.
    --
    -- @GtkSizeGroup@ objects are referenced by each widget in the size group,
    -- so once you have added all widgets to a @GtkSizeGroup@, 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 with mode
    -- '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 with mode
    -- 'GI.Gtk.Enums.SizeGroupModeVertical' or 'GI.Gtk.Enums.SizeGroupModeBoth'.
    --
    -- = Size groups and trading height-for-width
    --
    -- ::: warning
    --     Generally, size groups don\'t interact well with widgets that
    --     trade height for width (or width for height), such as wrappable
    --     labels. Avoid using size groups with such widgets.
    --
    -- A size group with mode 'GI.Gtk.Enums.SizeGroupModeHorizontal' or
    -- 'GI.Gtk.Enums.SizeGroupModeVertical' only consults non-contextual sizes
    -- of widgets other than the one being measured, since it has no
    -- knowledge of what size a widget will get allocated in the other
    -- orientation. This can lead to widgets in a group actually requesting
    -- different contextual sizes, contrary to the purpose of
    -- @GtkSizeGroup@.
    --
    -- In contrast, a size group with mode 'GI.Gtk.Enums.SizeGroupModeBoth' can
    -- properly propagate the available size in the opposite orientation
    -- when measuring widgets in the group, which results in consistent and
    -- accurate measurements.
    --
    -- In case some mechanism other than a size group is already used to
    -- ensure that widgets in a group all get the same size in one
    -- orientation (for example, some common ancestor is known to allocate
    -- the same width to all its children), and the size group is only
    -- really needed to also make the widgets request the same size in the
    -- other orientation, it is beneficial to still set the group\'s mode to
    -- 'GI.Gtk.Enums.SizeGroupModeBoth'. This lets the group assume and count
    -- on sizes of the widgets in the former orientation being the same,
    -- which enables it to propagate the available size as described above.
    --
    -- = Alternatives to size groups
    --
    -- Size groups have many limitations, such as only influencing size
    -- requests but not allocations, and poor height-for-width support. When
    -- possible, prefer using dedicated mechanisms that can properly ensure
    -- that the widgets get the same size.
    --
    -- Various container widgets and layout managers support a homogeneous
    -- layout mode, where they will explicitly give the same size to their
    -- children (see [Box:homogeneous]("GI.Gtk.Objects.Box#g:attr:homogeneous")). Using homogeneous mode
    -- can also have large performance benefits compared to either the same
    -- container in non-homogeneous mode, or to size groups.
    --
    -- t'GI.Gtk.Objects.Grid.Grid' can be used to position widgets into rows and
    -- columns. Members of each column will have the same width among them;
    -- likewise, members of each row will have the same height. On top of
    -- that, the heights can be made equal between all rows with
    -- [Grid:rowHomogeneous]("GI.Gtk.Objects.Grid#g:attr:rowHomogeneous"), and the widths can be made equal
    -- between all columns with [Grid:columnHomogeneous]("GI.Gtk.Objects.Grid#g:attr:columnHomogeneous").
    --
    -- = 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">horizontal</property>
    -- >  <widgets>
    -- >    <widget name="radio1"/>
    -- >    <widget name="radio2"/>
    -- >  </widgets>
