Two weeks before taking the time to see saw no time has been very interested in the study of XML and graphics API 
  Feel that we did not imagine before so mysterious:) 

  Spent three're happy with the time to write this AS1.0 pure AS XML rolling, it counted as exercise.

  Description:

  NOTE: 
  ★ your domain terrible text entitled: wenben_txt.    As is the practice, I did not deal with interface, I am sorry:) 
  XML ★ You can modify the corresponding parameters. 
  ★ this with the rolling of the Basic components of the scrollbar all of the features, including the precise location, but also avoid the easy text input in the slider beating incident.    Of course, and the most crucial of all is: I only 2 of this rolling more than K! 
  ★ this work is purely for our own amusement and challenge themselves.    AS1.0 based on the prototype, code written in relatively indiscriminate, senior master exhibitions.
