mirror filping ???

hell guys,

If i draw a rect using painter ... how can mirror it using the the origin point. ????

thanks

QPainter::scale() with a negative scale factor works (if I understood your question):

Code:

---

class Widget: public QWidget
{
    Q_OBJECT
public:
    Widget(QWidget *p = 0): QWidget(p) {
        resize(640, 480);
    }
 
    void paintEvent(QPaintEvent *event) {
        QRect r(50, 50, 200, 100);
 
        // for a bit of colour
        QLinearGradient linearGradient(r.topRight(), r.bottomLeft());
        linearGradient.setColorAt(0.0, Qt::white);
        linearGradient.setColorAt(0.2, Qt::green);
        linearGradient.setColorAt(1.0, Qt::black);
 
        QPainter p(this);
        p.translate(320, 0);    // put x origin in centre
 
        p.setBrush(linearGradient);
        p.drawRect(r);
 
        p.setPen(Qt::red);
        p.scale(-1.0, 1.0);
        p.drawRect(r);
 
    }
};

Great this exactly what i mean.

but now i faced other problem ... I have text along the rect sides (bottom and left) when i flip the text show flipped as well, is there a way where i can make the Text show correctly but still in the direction of the painter ?

Thank you so much

Added after 44 minutes:

I tried to use

p->setLayoutDirection(Qt::RightToLeft);

but it didn't work, it didn't show any affect actually.

You need to calculate where the text should go and then QPainter::translate() QPainter::drawText() it yourself.
