Qt community,
David, thanks that definitely seems to be heading in a promising direction.
It does create a challenge though. The model that I am using for my
QTableView inherits from QAbstractTableModel. Your proposal appears to
require that I change my model to instead inherit from
QStandardItemModel, cotrrect? It is this change of inheritance that
appears to be creating issues with an existing call to
<...Model>::index(int row,int column, const QModelIndex & parent =
QModelndex() ) const in my existing code.
In my existing call I do not pass a parent argument and therefore use
the default. This worked fine when the call was ultimately to
QAbstractTableModel::index(...) but appears to be returning an invalid
index (-1,-1) when the call ends up calling
QStandardItemModel::index(...). I am certainly willing to pass an
explicit parent argument, but am not sure how to generate a valid parent.
As always any help would be appreciated please. Thanks again.
Sincerely,
Carl
