Description Laszlo Gombos 2010-03-19 00:16:59 PDT
It seems that the QtWebKit tiled backing store needs the QGraphicsItem::scale function (seeQGraphicsWebViewPrivate::updateTiledBackingStoreScale).

I propose to turn off TILED_BACKING_STORE if Qt version is earlier than Qt4.6 (instead of making it work on Qt 4.5 or earlier).

QGraphicsItem::scale is present in Qt 4.5, but it's not a Q_PROPERTY in QGraphicsObject.

i confess I do not know what is the current minimum version of Qt that QtWebKit has to support. 

one mentioned it is current release (4.6) and the next (4.7). If so, should we care much about 4.5?

just out of curiosity.
