        This is a decorator applied to Python methods of a QObject that marks them
        as Qt slots.
        The non-keyword arguments are the types of the slot arguments and each may
        be a Python type object or a string specifying a C++ type.
        name is the name of the slot and defaults to the name of the method.
        result is type of the value returned by the slot.

Though they do not give full blown examples they give what arguments expected and what it returns, and constants.

Just thought of something....you can also use nullege
