Qtreeview Qabstractitemmodel Parent Collapses After Deleting Item And Sometimes Crashes

Im trying to build a little list of entries within a QTreeView, and based on the example posted here, I got it to delete any child items via the right click context menu i added. b

Solution 1:

beginRemoveRows() expects the QModelIndex, which is the parent of the QModelIndex to be removed, as the first parameter. Regarding the example that you indicate in the comments of your code in the table type models, the indexes do not have a parent, so it is passed an invalid QModelIndex.

def removeRow(self, rowIndexes):
    child_tree_item = rowIndexes[0].internalPointer()
    parent_item = child_tree_item.parent()
    self.beginRemoveRows(
        rowIndexes[0].parent(), rowIndexes[0].row(), rowIndexes[0].row() + 1
    )
    parent_item.removeChild(child_tree_item)
    self.endRemoveRows()
