How to reset model without collapsing tree?

[neuronet]

I have a QTreeView of a QStandardItemModel. I have a button that allows the user to move a row up in the tree among its siblings, and I do this using QStandardItem.takeRow() and QStandardItem.insertRow().

In pseudocode, I have:

model.beginResetModel()
 
#perform insert and take operations here
 
model.endResetModel()
view.expandAll()

model.beginResetModel()

#perform insert and take operations here

model.endResetModel()
view.expandAll()

To copy to clipboard, switch view to plain text mode 

My concern is that I am doing something wrong because I need to put in the expandAll() for things to work: otherwise when I reset the model the view collapses the entire tree. Is there a way to reset my model without having to re-expand my tree?
