[Qt-interest] Model Index Iteration

[Scott Aron Bloom]

If you have the model...

Just do something like
For( int row = 0; row < model->rowCount( parentIdx ); ++row )
{
   For( int col = 0; col < model->columnCount( parentIdx ); ++col )
   {
        QModelIndx idx = model->index( row, column, parentIdx );
        .....
   }
}

I have a QComboBox with a derived QStandardItemModel.  I need to iterate
over the entire model in order to reset a property on each item.  I've
gone through the docs but cannot figure it out.  Given that I have a
QAbstractItemModel* (actually a pointer to my derived type, of course)
how do I iterate the entire model and gain access to each item?  A code
snipper would be really helpful!

Thanks.
