Excellent!!! thank you Wysota and Lykurg for the precious help.

Last consideration to close the topic: considering this code is part of a large painter block of code and there is also others global painter trasformation I not want to loose or change
( painter.setWorldTransform(QTransform,true);

Is correct to write the follow code to restore painter state, without resetting al the painter trasformation matri,x doing another trasform after the text drawing?

QPainter p(this)
p.scale(-1,1);
p.drawText(...);
p.scale(-1,1); //reset the trasform whith another contrary trasform

QPainter p(this)
p.scale(-1,1);
p.drawText(...);
p.scale(-1,1); //reset the trasform whith another contrary trasform

That's possible but you also can use QPainter::save() and QPainter::restore():

QPainter p(this);
// use p
p.save();
p.scale(-1,1);
p.drawText(...);
p.restore();
// now p is like before "save()".

QPainter p(this);
// use p
p.save();
p.scale(-1,1);
p.drawText(...);
p.restore();
// now p is like before "save()".

This approach is much easier if you do more complex transformations.
