Edit: TreeWidget.py

# XXX TO DO:
# - popup menu
# - support partial or total redisplay
# - key bindings (instead of quick-n-dirty bindings on Canvas):
#   - up/down arrow keys to move focus around
#   - ditto for page up/down, home/end
#   - left/right arrows to expand/collapse & move out/in
# - more doc strings
# - add icons for "file", "module", "class", "method"; better "python" icon
# - callback for selection???
# - multiple-item selection
# - tooltips
# - redo geometry without magic numbers
# - keep track of object ids to allow more careful cleaning
# - optimize tree redraw after expand of subnode
