[Qt-interest] QGraphicsItem::ItemSendsScenePositionChanges has no effect in Qt 4.6.3

[Malyushytsky, Alex]

From documentation QGraphicsItem::ItemSendsScenePositionChanges is "Internal only" in 4.6.3.
I guess this is a reason it does not work.

Could you just set ItemSendsGeometryChanges and listen to QGraphicsItem::ItemPositionChange?
It works in 4.6.3 and I think it provides all information you might need.

I have a QGraphicsPixmapItem subclass, and in its ctor I set the
following flag:

   setFlag(QGraphicsItem::ItemSendsScenePositionChanges, true);

in order to have QGraphicsItem::itemChange() getting called whenever the
items is moved.  This works just fine in Qt 4.7.  However, in 4.6.3, the
version I need to support (Debian 6 uses that version), it doesn't.
According to the docs though, it should work:

   http://doc.trolltech.com/4.6/qgraphicsitem.html#GraphicsItemFlag-enum

   "This flag was introduced in Qt 4.6."

Is there something I can do?  Qt 4.6 support is important in my case.
