is that a method one overrides? where is "rowCount()" defined?
do i override it by subclassing QSortFilterProxyModel?

i think this is already happening

wouldn't the view ask the model for whatever data is revealed as visible, all
by itself?
so no need to show mock data? the point is i want to show the real data, even
if the user jumps to the last rows immediately
do i *need* to manually do this?
thanks for the suggestions, i'm trying to understand
