There are various ways, but there is not a stock 'isVisible' flag for  
model items that I am aware of. For an application I wrote that had a  
search field, as the user typed into the search field, I would  
reevaluate an isFiltered() method for each model item, executing  
setRowHidden appropriately. If the model changes dynamically, say from  
new data over the network, you could provide a 'visible'  value from  
the model data() method (at least that is what I'd try first).
