Sorting a QList containing structured datas

[jean]

Hi everybody,

I am sorry for posting what is probably a stupid question but I failed to find by myself the answer... sorting a Qlist with qSort() is tricky when the list only contains a single variable. But using a structure, it failed since the qSort() algorithm did not knows which field in the structure is to be sorted. Here is my code :

struct myData{
   QString namefile;
   int filesize;
};
 
QList <myData> list;
populatelist();
...

struct myData{
   QString namefile;
   int filesize;
};

QList <myData> list;
populatelist();
...

To copy to clipboard, switch view to plain text mode 

now how to sort list by namefile or filesize ?
I presume I need some pointers, but as newbie, I turn around it unsuccessfully. Thank you for any help.
