本文实例讲述了基于wxpython开发的简单gui计算器。分享给大家供大家参考。具体如下：

# 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 ...
