[Pythoncard-cvs] PythonCard/samples/iacGrid iacGrid.py,1.6,1.7

[Kevin A. <ka...@us...>]

Update of /cvsroot/pythoncard/PythonCard/samples/iacGrid
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv25077

Modified Files:
	iacGrid.py 
Log Message:
turned off cell editing and added dynamic grid expansion
  these don't seem to be causing a crash, so the earlier problem
  might have been the ansi version of wxPython
renamed the main class to IacGrid
removed self.log and some extra comments
