[Qt-interest] Accessing the source model of a QSortFilterProxyModel after filtering

[Andreas Ntaflos]

Hi list, 

I have a custom hierarchical tree model that provides several methods 
for accessing an item's data (kind of like the record() method of a 
QSqlQueryModel which returns the SQL record of a given item). I.e. 
treeModel->type(QModelIndex &) returns the type of the item with the 
given QModelIndex. This tree model is set as source model for a 
QSortFilterProxyModel, which in turn is set as the model for a 
QTreeView. 

After the proxy model does its filtering I'd like to be able to call the 
mentioned methods on the source model. Problem is: from where do I get 
valid indexes to call e.g. the type() method on the source model? I 
apparently can't use the indexes provided by the QTreeView's selection 
model.

So how do I create valid indexes I can use to access the source model 
after the filtering?

Hope this made sense :)

Thanks in advance, 

Andreas
