Bump!
I found this post regarding mirroring of QGraphicsItems: https://stackoverflow.com/questions/106 … left-right
Apparently you can simply apply
item->setTransform(QTransform::fromScale(-1, 1))I could not try it out myself, as compiling QET on windows is quite a hassle.
Even if it wouldn't be perfect (as I expect letters and numbers to be mirrored as well) it would be very useful.
