Hi,
I'm expiriencing some problems with selection using a custom tree model and QTreeView.
Here is the code for the model:

Qt Code: 
  1. #include "sessionstartendmodel.h"
  2.  
  3. #include <QDebug>
  4.  
  5. static constexpr quintptr STATION = quintptr(-1);
  6.  
  7. SessionStartEndModel::SessionStartEndModel(QObject *parent) :
  9.     m_mode(StartOfSession)

  12. }
  13.  
  14. QVariant SessionStartEndModel::headerData(int section, Qt::Orientation orientation, int role) const
  15. {
  16.     if(orientation == Qt::Horizontal && role == Qt::DisplayRole)

  18.         switch (section)
  19.         {
  20.         case RsNameCol:
  21.             return tr("Rollingstock");
  22.         case JobCol:
  23.             return tr("Job");
  24.         case PlatfCol:
  25.             return tr("Platform");
  26.         case DepartureCol:
  27.             return m_mode == StartOfSession ? tr("Departure") : tr("Arrival");
  28.         default:
  29.             break;
  30.         }

The QTreeView should select the complete row:
Qt Code: 
  1. view = new QTreeView(this);
  2. view->setModel(model);
  3. view->setSelectionBehavior(QAbstractItemView::SelectRows);
  4. view->setSelectionMode(QAbstractItemView::SingleSelection);
To copy to clipboard, switch view to plain text mode 

Instead when I click on indexed on first column only 1 index gets selectd, when clicking on other columns nothing happens instead of selecting entire row.
When single clicking parent rows nothing happens (maybe this is intended behaviour)

Thanks in advance
