1 # wxCalc1 a simple GUI calculator using wxPython
   2 # created with the Boa Constructor which generates all the GUI components
   3 # all I had to do is add some code for each button click event
   4 # Boa free from: http://boa-constructor.sourceforge.net/
   5 # note that    boa-constructor-0.3.1.win32.exe
   6 # still uses   wxPythonWIN32-2.4.2.4-Py23.exe
   7 # but is expected to work with wxPython version 2.5 soon
   8 # Python23
