To specify custom drawing for an item you need to specify a custom 
QItemDelegate for the view.

By overriding the delegates paint() method, you can specify what you 
like to draw and how to do it. The StarDelegate example illustrates how 
to use custom delegates, though it renders stars rather than html.

To get rich text in there, you should use a QTextDocument and the 
function drawContents()
