自己看，不解释。

#include <QtGui>
class Widget : public QWidget
{
public:
Widget(QWidget *parent = 0): QWidget(parent){}
void paintEvent(QPaintEvent *)
{
QPainter p(this);
#if 1
QTextDocument document;
document.setHtml(" T e s t ");
document.drawContents(&p);
#else
drawRotatedText(&p, 90, width() / 2, height() / 2, "The vertical text");
#endif
}

void drawRotatedText(QPainter *painter, float degrees, int x, int y, const QString &text)
{
painter->save();
painter->translate(x, y);
painter->rotate(degrees);
painter->drawText(0, 0, text);
painter->restore();
}
};

int main(int argc, char **argv)
{
QApplication a(argc, argv);
Widget w;
w.resize(200,200);
QString string = "test ";
QLabel label;
label.setText(string);
label.show();
w.show();
return a.exec();
}
