Problem trying to create a QString matrix

jss193

Hello, I have created a model in which I wish items to be editable and I want to store items such as:

private:
    int rows=0;
    int columns=5;
    int count = 1;
    QString m_gridData[rows][columns];

in m_gridData are stored the values, but in my class I need the number of rows and columns to be dynamic since I add rows during execution time but this QString matrix need cols and rows not to be a class variables and it needs const int values...How can I to make this matrix size editable as I am running my app.

Thanks!

Hi,

Something like a QVector<QVector<QString>> ?

Yes, by doing:

QVector<QVector<QString> > *m_gridData = new QVector<QVector<QString> >;

But how do I add values from data into rows and column?
What I want is to store data written in a tableview column editable into this matrix and I don't know how to do it.

Thanks

m_gridData[row][col] = "some string";

If m_gridData really has to be a pointer (does it?):

(*m_gridData)[row][col] = "some string";

There's usually no need to allocate your vector on the heap. Why do you need that ?
