About QAbstractProxyModel::sort(...) method

[zgulser]

Your model decides which field it maps into which column.

That's what models do: they provide an abstract interface to data. their main job is to define what a row means and what a column means in terms of the data they are working on.

You're absolutely right but it would be much better if there is a sort method which takes a Role as a parameter.

You mean like calling QSortFilterProxyModel::setSortRole() before sorting?

You are, of course, quite welcome to subclass either the model or the proxy to reimplement sort() however you want. The function is virtual for a reason.

It would still need a column.

The model can use whatever it wants for sorting, the sorting key doesn't even have to be accessible through a role.
Of course the model can always allow to set a sorting role as additional information if a single column can be sorted differently depending on what role one is using.
