Hello,

You can do that by a "wxGridCellAutoWrapStringEditor".
You can test it by modifying GridSimple.py in the demo by adding (at line 24
in my version):
self.SetRowSize(1, 45)
self.SetCellEditor(1, 1, wxGridCellAutoWrapStringEditor())
Save it and now, when you launch the gridsimple in the demo (it's in core
windows control), you can enter multiple lines in the cell containing
"Another cell". It works in 2.4.2.4. I think it should also in 2.5.

I join the whole program.
Have fun.
