Jim,
I have to solve a similar puzzle soon. Here's the approach I'm going
to try.
def make_button(this, that):
# dummy_button has the text but is lowlighted without an A helper
if should_return_dummy_button:
return lowlightedbutton
else:
return workingbutton
links = [lambda row: make_button(row.this, row.that. ...)]
