# Scrolledtext
|

|
|
# ----------------------------------------------------------------------
|
||
|
|
# Implements a scrolled text widget with additional options to manage
|
||
|
|
# the vertical scrollbar. This includes options to control the method
|
||
|
|
# in which the scrollbar is displayed, i.e. statically or dynamically.
|
||
|
|
# Options also exist for adding a label to the scrolled text area and
|
||
|
|
# controlling its position. Import/export of methods are provided for
|
||
|
|
# file I/O.
