Ok , i define my model like that
in ogrewidget.cpp
Qt Code: 
  1. QStandardItemModel* OgreWidget::add_object(/*Ogre::Real*/double offsetX ,/*Ogre::Real*/double offsetY)
  2. {
  3. .................................................
  4. model= new QStandardItemModel();
  5. 	int i=1;
  6.     for(itr = result.begin() ;itr != result.end();++itr)
  7.       {
  8.             if(itr->movable)
  9.             {
  10.  
  11. 				MarkerNode->_setDerivedPosition(mouseRay.getPoint(itr->distance));
  12. 				MarkerNode->setScale(0.1f, 0.1f, 0.1f);
  13. 				QStandardItem *item=new QStandardItem(QString ("Marker  %0").arg(i));
  14. 				model->appendRow(item);
  15. 				i++;
  16.  
  17.             }
  18.       }   
  19. 	  return model;
  20. }
To copy to clipboard, switch view to plain text mode 
and in my_interface.cpp
Qt Code: 
  1. list_O = new QToolButton(page_13);            
  2.             list_O->setGeometry(QRect(30, 210, 101, 31));
  3.             list_O->setText(QApplication::translate("MainWindow", "Object Liste", 0, QApplication::UnicodeUTF8));
  4. 	  listView =new QListView(list_O);
To copy to clipboard, switch view to plain text mode 
but it still do not make to me the list
