[PyQt] [PYQT] Increse the regex in QtCore.QRegExp

[Maziar Parsijani]

Hi,
I use this code in Qtextedit to find "sth" but the problem is when I have
more data it is lack on speed.
"""

cursor = self.SearchResults.textCursor()
format = QtGui.QTextCharFormat()
format.setBackground(QtGui.QBrush(QtGui.QColor("red")))
pp = self.m
pattern1 = r'\b(?:{})\b'.format(pp)
regex = QtCore.QRegExp(pattern1)
pos = 0
index = regex.indexIn(self.SearchResults.toPlainText(), pos)
tedad = 0
while (index != -1):
    cursor.beginEditBlock()
    cursor.setPosition(index)
    cursor.movePosition(QtGui.QTextCursor.NextWord,
QtGui.QTextCursor.KeepAnchor, 1)
    cursor.endEditBlock()
    cursor.mergeCharFormat(format)
    pos = index + regex.matchedLength()
    index = regex.indexIn(self.SearchResults.toPlainText(), pos)
