In Qt instead of rotating/scaling (e.g. transforming) objects, we transform the painter. It's much easier like this as soon as you get used to;-)

Thanks for your suggestion and the linked article, that is a little complicated for my project. May be rotate QPainter is the only way to draw vertical text. I supposed to edit the whole text via QTextDocument and render them to QPainter, if rotating/translating the QPainter, all the text will be rotated or translated.

i think i have to draw the contents of QTextDocument twice, once drawing horizontal text, then rotating the QPainter and drawing the vertical text. is that right?
