-- <description>
-- A box is a container that can have multiple children, organized either
-- horizontally or vertically. Two subtypes are provided, Gtk_Hbox and
-- Gtk_Vbox, to conform to the C API. In Ada, you do not need to distinguish
-- between the two, but note that the Gtk_Box type is conceptually an abstract
-- type: there is no way to create a "Gtk_Box", only ways to create either an
-- horizontal box, or a vertical box.
--
-- Children can be added to one of two positions in the box, either at the
-- beginning (ie left or top) or at the end (ie right or bottom). Each of
-- these positions can contain multiple widgets.
--
-- Every time a child is added to the start, it is placed to the right (resp.
-- the bottom) of the previous widget added to the start.
--
-- Every time a child is added to the end, it is placed to the left (resp.
-- the top) of the previous widget added to the end.
--
-- There are a number of parameters to specify the behavior of the box when
-- it is resized, and how the children should be reorganized and/or resized.
--
-- See the testgtk example in the GtkAda distribution to see concrete
-- examples on how all the parameters for the boxes work.
