if you dont grasp the concepts perhaps you should read the wiki page on
models
the concept is:
since the checkbox works by setting/clearing a boolean the model translates
a set boolean->insert into collection and clear boolean->remove from
collection.
there is explanation there, try to read that too, not just look at the code.

I don't quite grasp the concepts used in that tread. from what i
understand i
should create a separate model that takes the model that has to get
set(the
model that is selected via checkbox) in the object i'm making, and places
it
in a collection if it is selected. Is this correct?
