Items in QTreeView being replaced by QStandardItem when dragging

Hi and welcome to devnet,

That should already be the case if you are using the InternalMove drag & drop mode.

@SGaist Hey, thanks for your very prompt response.

Just implemented the InternalMove as you suggested, however when the item is dropped, it still gets replaced by a fresh instance of a QStandardItem.

Did you re-implement a model yourself ?

I used a QStandardItemModel.
Heres a super stripped down version of my code:

from PySide import QtGui, QtCore

class QTreeViewCustom(QtGui.QTreeView):
    def __init__(self):

        super(QTreeViewCustom,self).__init__()

        self.setDragDropMode(QtGui.QAbstractItemView.InternalMove)
        self.setDragEnabled(True)
        self.setDropIndicatorShown(True)

        self.dataModel = QtGui.QStandardItemModel()
        
        self.root = self.dataModel.invisibleRootItem()
        self.root.setDropEnabled(True)

        self.setModel(self.dataModel)
        self.setSelectionMode(QtGui.QAbstractItemView.SelectionMode.ContiguousSelection)

        #fill the tree with items
        for i in range(10):
            self.root.appendRow(testItem(str(i)))

class testItem(QtGui.QStandardItem):
    def __init__(self,name):

        super(testItem,self).__init__()
        self.setText(name)
