    Default QStandardItemModel limits

    folks,

    I used a QStandardItemModel to display a bunch of numbers.. and found that my apps crush if the number of items (row) is really big like 25000.

    so i was wondering if QStandardItemModel has limitation in rows or its the QTableView has limitation by the way i used QTableView as my viewer.....

    Can you provide a minimal compilable example reproducing the problem?

    Qt Code:
    1. #include <QtGui>
    2.  
    3. #include <QPushButton>
    4.  
    5.  
    6. int main (int argc,char *argv[])
    7. {
    8. QApplication app(argc,argv);
    9.  
    10. QTableView view;
    11. view.setModel(&model);
    12. for (int row = 0 ; row <20000 ; row++)
    13. {
    14. QStandardItem* item = new QStandardItem(row+1);
    15. model.setItem(row, 0, item);
    16. }
    17. view.show();
    18.  
    19. return app.exec();
    20. }
    To copy to clipboard, switch view to plain text mode
