They are synonymous, but afaik they are all defined as dashes,
generally I always use dashes.

One slightly relevent thing though, when dealing with the GObject
"notify" signal, the
dash and underscore are not synonymous for the property names
(i.e. "notify::button-style" is not synonymous with "notify::button_style")

Through normal property accessors; dashes and underscores are also synonymous,
i.e. g_object_get (object, "button-style", &style, NULL) is the same as
g_object_get (object, "button_style", &style, NULL).

I believe the only exception here really is the signal detail
arguments that depict
property names.
