get-text

Gets the text representation for this snip.

• (send a-wx:snip get-text offset num flattened?) -> string
      offset : small integer
      num : small integer
      flattened? = #f : boolean

  Returns the text for this snip starting with the item position offset within the snip, and continuing for a total length of num items. (If offset is less than 0, 0 is used for the offset. If offset is greater than the snip's count, then "" is returned. If num is greater than the snip's count minus the offset, then text from the offset to the end of the snip is returned.)

  If flattened? is not #f, then flattened text is returned. See Getting Text for a discussion of flattened vs. non-flattened text.
