[Qt-interest] Can QTextEdit scale in the way what QGraphicsView does?

[Guido Seifert]

Nope, works fine in 4.6.
But you just cannot add a text widget to a graphics scene.
To to this you need the QGraphicsProxyWidget. You find an example
how to do it in your qt's demo folder under 'embeddeddialogs'.
