    Have anyone use TableView to handle a lot of data(10000 rows, 5 columns)?

    I need to update the model(listModel) at most 100 times per second
    Every time I update, i need to do one comparison(atleast) and update the model.
    In most of the time, I only need to rewrite one row(top row), other rows(9999) could be moved down
    I plan to process the data by c++ and feed the data to qml site

    I only used qml for simple, small task
    haven't try to use it for performance critical task

    The other thing I concern is that qml and c++ still cannot pass the parameter by reference
