What is the best small 2-dim QT container?

[Raffael]

Hello,

I was wondering what would be the smallest and fastest 2-dimensional QT container?
I'm looking for something that will hold arrays of 60x60 up to 200x200 elements.
The values stored in the array would be 0,1,2 or I could split one big array to two same size arrays holding 0 and 1.

I've thought about using QVector< QVector<short> > or two QBitArrays.

The problem with

@QVector< QVector<short> >@

is that I don't know how to set it's size as normally it would go like

@QVector<short> vect(100)@

Next problem is how to access elements. First thing that comes to my mind is:

@vect.at(X).at(Y)@

As for the QBitArray I couldn't find any way to make it 2 dimensional.

All I need is reading/writing and maybe filling whole array.

Thank You for all responses.

You can use this:
@
typedef QVector< short > SubContainer;
const int size = 100;
QVector< SubContainer > vv( size, SubContainer( size ) ); @

As you said you can access elements with
@vv.at( x ).at( y )@
or with
@vv[ x ][ y ]@
