If I understand correcly, you want to disable the rubber band selection and still be able to left-click for select items (allowing the Ctrl modifier in order to select multiple items, one at the time).

So if this is the case, you need to use the QGraphicsView::setDragMode method and set QGraphicsView::NoDrag option. You can achieve this directly from your QGraphicsView object or subclassing QGraphicsView and adding the call to method on the constructor, like this (PySide):

from PySide.QtGui import *
from PySide.QtCore import *


class MyGraphicsView(QGraphicsView):
    def __init__(self, parent = None):
        super(MyGraphicsView, self).__init__(parent = parent)
        self.setDragMode(QGraphicsView.NoDrag)

If your graphic items have the Qt::ItemIsSelectable flag enabled, then you will still be able to select them as usual.

Hope it helps.
