回答1:

setModel is a private function in QTreeWidget. To use it, you could create a custom TreeWidget class that inherits QtreeWidget and QTreeView, create a public function setModel(QAbstractItemModel *model) and in it call the QTreeView setModelfunction like so:

 TreeView::setModel(QAbstractItemModel *model){
      QTreeView::setModel(model); 
 }
