--  <description>
--  Tooltips are the small text windows that popup when the mouse rests over
--  a widget, and that provide a quick help for the user.
--
--  In GtkAda, all tooltips belong to a group (a Gtk_Tooltips). All the
--  individual tooltips in a group can be disabled or enabled at the same
--  time. Likewise, the colors and style of a tooltip can be set on a group
--  basis.
--
--  See the example at the end for how to change the default colors used
--  for tooltips.

   --  All subprograms below are now obsolescent in gtk+. They might be removed
