[mythtv-theming] Adding a value to a page using the themes

[Johnny Walker]

Ok so I had this idea to add the next scheduled recording for a
program to the Watch Recordings screen - when you're highlghting the
group name and not a specific episode. There seems in that instance to
be this unused screen real estate and I thought it would a decent
feature to look into adding.

So I read the theming documentation and the following theme pages:

/usr/local/share/mythtv/themes/Mythbuntu/recordings-ui.xml
/usr/local/share/mythtv/themes/Mythbuntu/schedule-ui.xml

But it seems that if I want MythUi to fill in a textarea based on a
value for a program I would need to add that value to the ProgramInfo::ToMap
method so that it's an available value. Is that true?
