need help to classify some QStringList

[patcito]

I have a list which contains references and another contains prices of each reference. There are some duplicates. It looks like this:

QStringList refList;
QStringList priceList;
 
{code to fill each list}

QStringList refList;
QStringList priceList;

{code to fill each list}

To copy to clipboard, switch view to plain text mode 

I want to get the quantity of each reference and get the price of the sum of each duplicate so to get the result into two QStringList:

QStringList refListWithOutDuplicates;
QStringList priceList;

QStringList refListWithOutDuplicates;
QStringList priceList;

To copy to clipboard, switch view to plain text mode 

Any idea what's the best way to do this with Qt?


Thanx in advance
