editing a wxGrid

[marvin]

hi-

i worked on a project in TCL/TK found at j_m_mc.tripod.com.  I want to 
allow the user to edit the table using wxGrid and python.

I'm just looking for some tips.  For i.e. in sqlite and TCL most data is
represented as a string.  When do data types become an issue in this 
instance?  If I allow the user to edit directly in a cell it seems it 
doesnt really matter because you can only enforce data validation if i 
use a form anyways as far as the data types go.  I mean with sqlite the 
primary reason for using data types is in case i want to ever switch 
dbs.  I cant remember off the top of my head but I think access or 
paradox would complain if you used a string for instance in a date 
field.  So without some checking be in forced maybe it is not a good 
idea to directly allow editing in the table anyways.

Is a better way stepping through or searching the array that populates 
the TkTable query result and tying it to a form that validates somehow?

bottom line...i'm looking to extend my program a little and wondered
if anything along these lines is feasible.

thanks,
marvin
