QModelIndex values unexpectedly alternates

[anda_skoa]

I would even say it is bound to return a different object.

Exactly!
Even if the model would return the same object every time (which it doesn't), the caller would always get a different one since the API returns a copy, not a reference.

@q130s - Sorry, I misunderstood your intent (reading comprehension problem).

Like d_stranz, I'm not that familar with Python but where in your original code do you deselect the clicked on item? Does the following change work?:

if len(indexes) > 0:
            print(tabular_format.format(
                              del_or_sel, index_current, index_current.row(),
                              index_current.data(Qt.DisplayRole).toString(),
                              index_parent_sel, index_internalid))
	    self.selectionModel.select(index_current,QItemSelectionModel.Deselect) # added statement
        elif len(deselected.indexes()) > 0:
            print(tabular_format.format(
                              del_or_sel, index_deselected, index_deselected.row(),
                              index_deselected.data(Qt.DisplayRole).toString(),
                              index_parent_desel, index_internalid))
            #self.selectionModel.select(index_deselected,QItemSelectionModel.Deselect)  # not necessary

if len(indexes) > 0:
            print(tabular_format.format(
                              del_or_sel, index_current, index_current.row(),
                              index_current.data(Qt.DisplayRole).toString(),
                              index_parent_sel, index_internalid))
	    self.selectionModel.select(index_current,QItemSelectionModel.Deselect) # added statement
        elif len(deselected.indexes()) > 0:
            print(tabular_format.format(
                              del_or_sel, index_deselected, index_deselected.row(),
                              index_deselected.data(Qt.DisplayRole).toString(),
                              index_parent_desel, index_internalid))
            #self.selectionModel.select(index_deselected,QItemSelectionModel.Deselect)  # not necessary

I haven't noticed that there has been responses (no email update feature?) but thanks for that.

I think I worked it around by something similar to what norobro suggests...comparing qindex.data. Since this works fine for me I'll keep using it but next time when I implement the similar feature I'll think about storing row & column.
