TreeModel & QTreeView header data not displayed



  • Hi,

    I followed the Simple Tree Model example (here) to make a tree model/view but I can't see the header data like title/summary...

    I hard coded the header data like this:

     QVariant TreeModel::headerData(int section, Qt::Orientation orientation, int role) const
     { 
         return "HeaderData !!!";
     }
    

    But nothing appears onto the view !
    I just see empty space.

    Any idea ?

    Thanks !



  • I solved the problem, the working code is:

     QVariant TreeModel::headerData(int section, Qt::Orientation orientation, int role) const
     { 
        if (role != Qt::DisplayRole)
             return QVariant();
        return "HeaderData !!!";
     }
