you get the error message because you try to instantiate an InchesX
object by calling an Inches constructor.

you are mixing "extending a class" with "deriving a subclass"

you can do both. either you extend a gui class like this:

class Inches
# ... foxguib generated code here
end

class Inches
  def init
    # ... your extension code here
  end
end

or you derive from the foxguib class which looks like this:

class DerivedInches < Inches
  def initialize parent
    super
    # ... your code here
  end
end

hope this helps,
