sizers.py

用wxPython编写GUI程序的样例代码

# 11/26/2003 - Jeff Grimmett ([e-mail])
#
# o Had to do a bit of rework for the demo; there was no panel attached
#   to the demo window, so all buttons were showing as dark gray on
#   dark gray. I have no idea why this didn't break before. Robin,
#   please examine my changes to ensure you approve. It's rather
#   hackish looking.
