[SOLVED]How to store data present in the tableview in any 2D array ?

Ratzz

I have a tableview which is contains 32 rows and 32 column . Each cell is a comboboxdelegate (each cell is a combobox) which contains several items in the list. User has the ability to change the values of comboboxdelegate .I have a radiobutton "Tx" and "Rx" . on clicking "Tx"/"Rx" the tableview should display the values which was selected by the user for Tx/Rx in the same tableview. I have to store the data for each of Tx/Rx in a 2D array and update the data as the user updates. On Tx/Rx radiobutton click i want to retrieve the value from 2D array and display it in the tableview .
How to store data present in the tableview in any 2D array ? and how to retrieve the value from 2D array and display it in the tableview?

Hi,

You can build your own model on top of e.g. two QVector<QVector<whatever_type_you_need>> that you will switch when changing Tx/Rx

Hope it helps

Hi.Thanks for the reply.
How about storing values in Qstring ?

    QString TxDataTables[32][32];
    for(int row=0;row<32;row++)
    {
        for (int column=0;column<32;column++)
        {
         QModelIndex index = DataTableModel->index(row, column, QModelIndex());
         TxDataTables[row][column] = index.data().toString();
        }
    }

how to retrieve the data when Tx/Rx changed ?

Depends on whether you store both information in your strings or if you have two tables

I want to store the data in the string .

SGaist

Then you have to parse the string each time. Wouldn't it be more practical to use a QPair ?

I have done it with the structure

RTStruct *rtStruct;
    for(int row=0;row<32;row++)
    {
        rtStruct = rtList.at(row);
        for (int column=0;column<32;column++)
        {
       QModelIndex index = DataTableModel->index(row, column, QModelIndex());
            if(addressArea == TX)
            {
                rtStruct->txDataTables[column] = index.data().toString();
            }
            else
            {
                rtStruct->rxDataTables[column] = index.data().toString();
            }
        }
    }

How to do it with Qpair?

If you already have a struct that fits your needs then no need to change anything

@SGaist
Yes, It worked me out.
