How to display in QTableWidget the required row in the middle of the visible area of ​​the table?

Question

Python

A PyQt4 application connects to a sqlite database with a single table and processes a query to select all records for which a unique value of the vec column is entered in qlineedit and, in addition to this desired record, a number of records are displayed before and after it.
Extract from code:
##############################
from PyQt4 import QtCore, QtGui
import sys, MyForm
import sqlite3
cnn = sqlite3. connect('sqlite/data.sqlite')
c = cnn.cursor()
class Prog(QtGui.QWidget, MyForm.Ui_MyForm):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self .setupUi(self)
self.btnSrch.clicked.connect(self.outputResults)
def outputResults(self):
c.execute("select * from data where vec>? and vec<?", (vec1,vec2,))
# then populate the qtablewidget with the query results and navigate to the desired record using the following method:
for i in xrange(self.tableWidget0.columnCount()):
self.tableWidget0.scrollToItem(self.tableWidget0.item(vec,i))
#################### #######################################
_ With scrollToItem, the item being searched is displayed either at the top or bottom of the visible area of ​​the table, depending on whether the searched item is currently above or below the visible one. How can I make the required record always appear in the middle of the visible area of ​​the table?

Answer 1

scrollToItem(self.tableWidget0.item(vec,i), QtCore.QAbstractItemView.PositionAtCenter)
