# wxpython: multiline text cell with wrap and enter in wx.grid?
#
# I would like to have a multiline text cell in a grid that
# behaves in a manner similar to a multi-line text control.
# In particular, that wraps lines to fit the cell
# and that inserts an explict line break when the return key is pressed.
#
# I've searched high and low for a way, but havn't found one published.
# Any hep would be greatly appreciated.
