[Qt-interest] QTableView navigation with edit strategy OnFieldChange

[Mark Brand]

> Hi,

> One approach I've toyed with is overriding the model's select(),
> blocking the model's normal signals during the select(), and afterwards

After posting, I found a description of the problem here:

Still need a workaround though..
