jpayne@69 1 # XXX TO DO:
jpayne@69 2 # - popup menu
jpayne@69 3 # - support partial or total redisplay
jpayne@69 4 # - key bindings (instead of quick-n-dirty bindings on Canvas):
jpayne@69 5 # - up/down arrow keys to move focus around
jpayne@69 6 # - ditto for page up/down, home/end
jpayne@69 7 # - left/right arrows to expand/collapse & move out/in
jpayne@69 8 # - more doc strings
jpayne@69 9 # - add icons for "file", "module", "class", "method"; better "python" icon
jpayne@69 10 # - callback for selection???
jpayne@69 11 # - multiple-item selection
jpayne@69 12 # - tooltips
jpayne@69 13 # - redo geometry without magic numbers
jpayne@69 14 # - keep track of object ids to allow more careful cleaning
jpayne@69 15 # - optimize tree redraw after expand of subnode
