[Interest] Tool tip for a QTableView column heading?

[Carl Schumann]

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
