Same way you'd do it from the superclass:

class A_Test < ObjectMap
     Login.new.username
end


Note that username is not a method of ObjectMap but of the nested
class ObjectMap::Login

You could also do this from outside ObjectMap and it's subclasses like so:

ObjectMap::Login.new.username

If you made login and it's brethren class methods:

class Login
       def self.username;@@ie.text_field(:name, 'user_name');end
       def self password;@@ie.text_field(:name, 'password');end
       def self.remember_me;@@ie.checkbox(:name, 'remember_me');end
       def sign_in;@@ie.button(:value, 'Sign in');end
end

Then the above would be

class A_Test < ObjectMap
     Login..username
end

or from outside:

   ObjectMap::Login.username

Lacking more information about what you are really trying to
accomplish, your code looks a little odd to my eye.

ObjectMap seems like it really should be a module rather than a class
since from what you've shown it's really acting as what looks like a
name space.

You're using class variables which always raises a yellow flag in my mind.

Of course some of this could be Watir practice and I've never used Watir.
