Where can find a full list and description of the signal name

["Lazy Fox" <lazy fox wu gmail com>]

Just like "expose-event" and "expose-event",
I can't find all of them in the 'GTK+ Reference Manual' and source code.
And other string type enumerations such as color: "red", "orange".
I can't find them neither.

Does anybody know where can find the full list and description of the string type enumerations.
