How to reimplement removeRows in Tableview model

[hachbani]

Hello,

I'm displaying data in a QTableView, the data is stored in a model subclassed from QAbstractTableModel.

I'm trying to reimplement removeRows method to remove given rows from my table.

here's what I tried so far:

def removeRows(self, row:int, count:int, parent=None):
    self.beginRemoveRows(parent, row, row+count)
    self._items = self._items[:row] + self._items[row+count+1:]
    self.endRemoveRows()
    return True

self._items is a list of lists that contains all my rows.

the function returns an error for the moment at the first line of the code: beginRemoveRows doesn't like the None parent.

What I'm doing wrong ?

Thanks,

FIXED:

parent = QtCore.QModelIndex() instead of None.
