    Unhappy Huge tableview low performance

    Hi all!

    I need to display very large table with more then 100000x100000 cells
    I'am reimplement QAbstractItemModel to represent my internal data in each cell of standard QTableView

    But created table view is too slow for me ...
    I was testing simple item model what store 100000x100000 data structure and returns empty QVariant() for each data cell ... but even so tableview repaints too slow ....

    why?

    Or i have to reimplemen QAbstractItemView for better perfomance ...

    Qt version used: 4.1.1
