WAbstractItemModel has two setHeaderData functions:

One that is virtual and takes 4 arguments (section, orientation, value, and role), and another that serves
as a shorthand and takes 2 arguments (section and value), that calls the 4 argument function with orientation
set to Orientation::Horizontal and role set to ItemDataRole::Edit.

QueryModel overrides the 4-argument version, which causes the 2-argument function to be hidden.
using WAbstractItemModel::setHeaderData; should be added to QueryModel so that the 2-argument version
is accessible.
