Sort array

[ranger0]

Hi folks,

Any idea of what to do to sort an array writen like this:

@
QList< QList<QVariant> >
@

I want to choose a column to sort and the other QLists must have it´s order modified according with that one.

Thanks

Well there are several ways to do that:

1. Create your own function based on some "sorting algotythms":http://en.wikipedia.org/wiki/Sorting_algorithm;
2. Create some sheild class for using with qSort;
3. If you need display result data in some view you can create some custom model which contains your data and bind it with "QSortFilterProxyModel":http://qt-project.org/doc/qt-4.8/qsortfilterproxymodel.html

Hi qxoz. Thanks for your help!

I'm wondering if you could help me to realize how to link all columns.

I know I could use qSort to sort one QList, but how could I link that to the other ones?
