To create an arrow on the Print Composer I've used this:
qC = QgsComposition(iface.mapCanvas().mapRenderer())
arw = QgsComposerArrow(QPointF(0, 0),QPointF(10,10),qC)
However, I can't find an attribute or method to change any of the two points.
I've tried with:
but it seems to change the precision and swaps the arrow head to the other end with every change. The same happens using
.setSceneRect() . It seems to me this is not the way to go. Can anybody help me with this?
