Hi all!
Firstly, I should say thank you to Model/View arcitecture in Qt for the time it has saved.

Then I have a problem disturb me long time. The tableview in my program has a model which is QSortFilterProxyModel. It serves to sort and filter the data supplied by the source model. The source model hold the data which would change from time to time.
The requirement is : only demonstrate the first 3 rows of the sorted and filtered data!

Please give me a clue! I just donnot know where to start!
