Writing data of type QVector<QVector<QString>> into a text file

[ashajg]

Hi Guys,

I want to write some data into text file.
My data type is

QVector<QVector<QString>>table;

but I am getting an error

no match for 'operator<<' (operand types are 'QTextStream' and 'QVector<QVector<QString> >')

         out << table;
         ~~~~^~~~~~~~~~~~~~

How can I write this data to a file?

@ashajg The easiest way is to iterate through the lists:

for(const auto &v : table)
{
    for(const auto &str : v)
       out << str; 
}

I just have to add to @KroMignon, if table is not const, you should use qAsConst:

for(const auto &v : qAsConst(table))
{
    for(const auto &str : v)
       out << str; 
}
