-- The baseclass module uses upvalues to give the impression of inheritence.

-- At the top of your class file add
|

|
|
-- DEFINE_BASECLASS( "base_class_name" )
|
|

|
|
-- Now the local variable BaseClass will be available.

|
-- Baseclasses are added using baseclass.Set - this is done automatically for:
|
|

|
|
-- > widgets
|
|
-- > panels
|
|
-- > drive modes
|

-- Classes don't have to be created in any particular order. The system is
|
|
-- designed to work with whatever order the classes are defined.
|
|
--
|
|
-- The only caveat is that classnames must be unique.
|
|
-- eg Creating a panel and widget with the same name will cause problems.
