[bt-devel] tree keys and Qt4 Model/View architecture

[Martin Gruner]

Hi Eeli,

great. Since we don't have model/view in BT1/QT3, using QTreeWidget is 
probably the quickest and most simple solution. Maybe we can introduce M/V 
later, after the port.

I believe that one reason for the first test program's problems with tree 
display is

inline int columnCount(const QModelIndex &parent = QModelIndex()) const 
{return 1;}

It means that the Tree has only one level. Sub-Items have column+1 of their 
parent items, IIRC.

Best regards,

mg
