Qt 3D-array with Qt-Objekts like QVector

Question

How can I create a 3D-array only with Qt-Objects? The array should be a 3D-integer-array. I have tried to create a standard 3D-array on the heap. To allocate the memory on the h

#include 
#include 
#include 

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    int dim_0 = 3;
    int dim_1 = 3;
    int dim_2 = 3;
    int default_val = 0;
    QVector < QVector < QVector< int > > > vec(dim_0,
                                               QVector < QVector  > (dim_1,
                                                                           QVector < int > (dim_2, default_val)));

    for( int i = 0; i < dim_0; i++)
    {
        for ( int j = 0; j < dim_1; j++)
        {
            for ( int k = 0; k < dim_2; k++)
            {
                vec[i][j][k] = i*100 + j*10 + k;
            }
        }
    }

    qDebug() << vec;

    return a.exec();
}

Hope that helps.
