(SOLVED) Draw arc into qgraphicsview
-
I have:
Graphicsview dove;
Graphicsscene scene;
With
dove->setscene(scene).
if I want to draw an ellipse can do(and circle)
dove.scene.addellipse(........)
if I want to draw an rectangle can do
dove.scene.addrect(........)
But if I want to draw an arc as I do?
dove.scene.addarc not exist. -
You can create a QGraphicsPathItem, and set a QPainterPath that contains the arc you want to draw (use QPainterPath::moveTo and QPainterPath::arcTo)
-
I tried but does not work as I would like;
I would use drawArc of QPainter;
Someone could tell me how can I do? -
You can always create your own QGraphicsItem: Derive from QGraphicsItem, and implement paint and boundingRect.

I solved this way:
@ QPicture pi;
QPainter p(&pi);
p.setRenderHint(QPainter::Antialiasing);
p.setPen(QPen(Qt::black, 1));
p.drawLine(x1,y1,x2,y2);
p.end();
dove->setPicture(pi);
@where dove is a QLabels

You could use the same approach with a QPixmap and a QGraphicsPixmapItem. But if your current approach works well for you, that's certainly ok.
