Slip, sliding away

[Paul Dupuis]

Put the following in the script of the image that is inside the
scrolling group. You may also want to change the cursor to a hand on
mouseDown

on mouseDown
  set the hMin of me to 0
  set the hPos of me to item 1 of the mouseLoc
  set the hMax of me to the width of me
end mouseDown

on mouseStillDown
  get item 1 of the mouseloc
  put (the hPos of me - it) into tDelta
  set the hPos of me to it
  get the hScroll of the owner of me
  add tDelta to it
  if it < the hMin of me then put 0 into it
  if it > the hMax of me then put the hMax of me into it
  set the hScroll of the owner of me to it
end mouseStillDown
