Hi,<br>
<br>
I'd like to point out that, realistically, the QGraphicsView framework<br>
is obsolete. Yes, it may still be around a while.<br>
But: The new OpenGL based QtQuick 2.0 graphics stack is way better.<br>
<br>
I'm in the process of porting a C++ application from QGraphicsView<br>
to QtQuick 2.0, which used a lot of custom QGraphicsItems which are<br>
now QQuickItems. The performance increase is unbelieveable. And it's<br>
more powerful and has more features, too!<br>
<br>
I was very sceptical at first, as this make me dependent on hardware<br>
accelerated OpenGL now. But in the year 2013 this is really no problem.<br>
<br>
Of course, right now QtQuick 2.0 is out of reach for PyQt users.<br>
But that will change. And the new model fits the Python approach<br>
much better. In QGraphicsView, Python code is run every time a frame<br>
is drawn. In QtQuick, your Python code generates a description of the<br>
scene once, which is then drawn by the 3D-chip exclusively. Very fast.<br>
<br>
Best Regards,<br>
