Hi Seth,
Thanks for your reply. I have a callback connected to 'edited' on the
cellrenderer already, but it doesn't appear to be getting called here.
Seems like it's getting 'editing-canceled' when I call 'set_cursor',
which is why I thought I might have to emit 'edited' manually prior
to setting the cursor on the next cell.
Regards,
Jordan
