I'm just now learning to use CoreData and Bindings so be kind...
Say I've got a pretty simple Person Entity with attributes name,
mom, dad (among others). So far so good - I can add and remove
records from my table, etc.
Now say I'd like to show a sort of family tree...
dad
dad - |
mom
child - |
dad
mom - |
mom
I've got the GUI for the family tree set up already and it's even
printing nicely. I've bound the 'child' field to selection.name and
the first 'dad' and 'mom' fields to selection.dad/mom so they're
filled in (or I can easily grab their records and add more info).
Now what's going to be the easiest way to get the next (and the
next-next) generation?
TIA!
Hey yeah, check out how dumb I am...
I got rid of the bindings (so I can beautify/edit the tree w/o
modifying the table data), subclassed NSTextField, added two outlets
and overrode setObjectValue. I use the arg (the person's name) to get
the record, pull the mom and dad's name and pass those on to the two
outlets. Those fields then do the same until there's either no
records or no fields left...
Now all I have to do is pass the 'child' field a name and the tree
gets filled.
