If the OP wanted to display the selected state, you are right. You need 
a delegate (or a different style). But double clicking isn't changing 
the selected state, in my book. However, I may have misunderstood.

You can change the font by using QAbstractItemModel::data and returning 
something sensible for the Qt::FontRole. You can als modify colors 
(foreground and background) and alignment this way, along with some 
other properties.
