#This file has been modified to be used in gtk-recordMyDesktop
#by John Varouhakis
#Base class is DrawingArea instead of Window to allow insertion.
#new methods:
# update_image to keep the screenshot current.
# __subsample__ to scale the screenshot
# __draw_lines__ to highlight the selected area.
#Calls to destroy have been removed, since this widget is meant to
#live for an indefinite amount of time.
#Click behavior has been changed. Selection now happens by left-click and dragging,
#while right click resets the selection.
#original file name is select.py in Istanbul-0.2.1
