30.     --  Tooltips are the small text windows that popup when the mouse rests over

31.     --  a widget, and that provide a quick help for the user.

32.     --

33.     --  In GtkAda, all tooltips belong to a group (a Gtk_Tooltips). All the

34.     --  individual tooltips in a group can be disabled or enabled at the same

35.     --  time. Likewise, the colors and style of a tooltip can be set on a group

36.     --  basis.

37.     --

38.     --  See the example at the end for how to change the default colors used

39.     --  for tooltips.
