I want to say the last time I attempted this, I ended up setting the  
boolean column manually rather than using the mapper for the  
checkboxes. It's been a while though, so I may not be remembering  
correctly, or things may have changed in Qt. Note also that while this  
should be a functional workaround, it may not necessarily be the best  
option, and I would think in principle at least that using the mapper  
should work.
