[Solved] QHash and QVector

Mike_newbye

Hi,

I have some data read by lines from a .csv file

@
while(!file.atEnd())
{
...
line = file.readLine();
list = line.split(',');
...
listSize = list.size();
@

I also have to defined a QHash
@
QHash<QString, QVector<float> > hash;
@

Now I want to store the data read to the hash. I can fill in case if i have @int@ instead of @QVector<float>@. E.g.
@
for(int i = 1; i<= listSize; i++)
{
hash[QString::number(i)] = 1;
}
@

How to do it with @QVector<float>@ if i want to keep the rows/first element of each row in QVectors.##

Thanks in advance.

I solved it myself for filling lines to QVector, can anyone help to do it for rows??

@while(!file.atEnd())
{
line = file.readLine();
list = line.split(',');
QVector<float> vec;
for(int j = 0; j < list.size(); j++)
{
vec.push_back(list[j].toFloat());
}

    hash[line] = vec;
    //qDebug() << list;
}@

Hi,

I have some question about your logic:
Your hash key is the string representation of the QVector content, is that really what you want ?

What do you mean by rows ?

Hi,

Thank you for answering.
Actually I already solved it by myself as follows:

@for(int j=0; j<listSize; j++)
{
hash[headerList[j]].push_back(list[j].toFloat());
}
@

I need this kind of representation as I am doing clustering and I need to separately keep the data from the headers.

You're welcome,

But still... That logic seems very convoluted...

If everything is working now, please update the thread's title to solved
