problem in QLinef()

[wysota]

but how can i use this QLineF::setAngle() function ... where can i implement it ..

Don't use it with QGraphicsLineItem, it doesn't make much sense to do so in this context. Rotate the item, not the line within it.

thanks .. i will rotate the item as

QTransform transform;
        transform.rotate(90);
          line1 = new LineItem(QLineF(1,1, 132 ,160), Qt::blue, 90);
        scene->addItem(line1);
        line1->setPos(574,415);
        line1->setTransform(transform);

QTransform transform;
        transform.rotate(90);
          line1 = new LineItem(QLineF(1,1, 132 ,160), Qt::blue, 90);
        scene->addItem(line1);
        line1->setPos(574,415);
        line1->setTransform(transform);
