Hi Eric,
does this mean you would suggest to use txt1.cached[txt1.get_prop_tup()] to be
on the save side for
future versions? I'm aware of the leading underscore notation, however, the
txt.cached dictionary has
changed as well (without leading underscore and notice?), therefore, slight
modifications in the scrips
cannot be precluded anyway.
Regarding the renderer argument...
I first thought about passing a renderer instance to the _get_layout method,
but as I had no clue where
to get this instance from. So I simply tried with the backend name and luckly
it worked :).
Thanks again, and have a nice day!
Jakob
