Defining a two dimensional QVector class (Q2DDoubleVector)

[ufechner]

Hello,
I tried again, and now it works fine.

class Q2DDoubleVector : public QVector< QVector<double> > // Overloading Class QVector to allow for 2 dimensional vectors.
{
public:
    // constructor
    Q2DDoubleVector() : QVector< QVector<double> >(){}
    // methods
    // matrix resize
    void mresize(int rows, int columns);
    // destructor
    virtual ~Q2DDoubleVector() {}
};
 
void Q2DDoubleVector::mresize(int rows, int columns)
{
    this->resize(rows);
    for(int r=0; r<rows; r++) {
        (*this)[r].resize(columns);
    }
}
 
Q2DDoubleVector matrix;
matrix.mresize(ROWS, COLS);

class Q2DDoubleVector : public QVector< QVector<double> > // Overloading Class QVector to allow for 2 dimensional vectors.
{
public:
    // constructor
    Q2DDoubleVector() : QVector< QVector<double> >(){}
    // methods
    // matrix resize
    void mresize(int rows, int columns);
    // destructor
    virtual ~Q2DDoubleVector() {}
};

void Q2DDoubleVector::mresize(int rows, int columns)
{
    this->resize(rows);
    for(int r=0; r<rows; r++) {
        (*this)[r].resize(columns);
    }
}

Q2DDoubleVector matrix;
matrix.mresize(ROWS, COLS);
