def method_missing(name, *args)  # :nodoc:
  # -- original perl comment --
  # There are two types of set methods: set_property() and
  # set_property_color(). When a method is AUTOLOADED we store a new anonymous
  # sub in the appropriate slot in the symbol table. The speeds up subsequent
  # calls to the same method.

  method = "#{name}"

  # Check for a valid method names, i.e. "set_xxx_yyy".
  method =~ /set_(\w+)/ or raise "Unknown method: #{method}\n"

  # Match the attribute, i.e. "@xxx_yyy".
  attribute = "@#{$1}"

  # Check that the attribute exists
  # ........
  if method =~ /set\w+color$/    # for "set_property_color" methods
    value = get_color(args[0])
  else                            # for "set_xxx" methods
    value = args[0].nil? ? 1 : args[0]
  end
  if value.respond_to?(:to_str) || !value.respond_to?(:+)
    s = %Q!#{attribute} = "#{value.to_s}"!
  else
    s = %Q!#{attribute} =   #{value.to_s}!
