wxpython开发的简单的gui计算器

# wxCalc1 a simple GUI calculator using wxPython
# created with the Boa Constructor which generates all the GUI components
# all I had to do is add some code for each button click event
# Boa free from: http://boa-constructor.sourceforge.net/
# note that    boa-constructor-0.3.1.win32.exe
# still uses   wxPythonWIN32-2.4.2.4-Py23.exe
# but is expected to work with wxPython version 2.5 soon
# tested with Python23   vegaseat    26feb2005
from wxPython.wx import *
# some Boa generated global IDs ...
