How to get a pointer for 2D array of QVector?

[amleto]

This just doesn't make sense:

QVector<QVector<int> > myA2D;
 QVector< int* > tempPtA2D;
 int **pA2D;
 
 - tempPt2D[0] = myA2D[0].data() ....;
 - pA2D = tempPt2D.data();
 - int aaa = pA2D[][];

QVector<QVector<int> > myA2D;
 QVector< int* > tempPtA2D;
 int **pA2D;

 - tempPt2D[0] = myA2D[0].data() ....;
 - pA2D = tempPt2D.data();
 - int aaa = pA2D[][];

Can you tell me which part is wrong?

The following codes work:

QVector<QVector<int> > test2D;

test2D.resize(10);
for(int i=0; i<10; ++i)
{
(test2D[i]).resize(5);
}

for(int i=0; i<10; ++i)
for(int j=0; j<5; ++j) test2D[i][j] = 3*i+j;

yes, that 'works', but you cannot pass anything there to a fortran routine that expects a 2d array (int[][] for example).

Also, please use code tags in future.
