I mean when the "Event is activated" by leaving a cell (with a modified 
value). In the OnEndEdit() method i print the data contained in that 
column to stdout but this return the original data and not the last 
change. Now... if i OnEndEdit the same item again the data returned it 
is the modified.

Thanks in advance!

PD: I hope to be clear now :)

The sample from the wxPy doc slightly modified:

1 : ("Hey!", "You can edit", "me!"),
2 : ("Try changing the contents", "by", "clicking"),
3 : ("in", "a", "cell"),
4 : ("See how the length columns", "change", "?"),
5 : ("You can use", "TAB,", "cursor down,"),
6 : ("and cursor up", "to", "navigate"),
}
