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 to change any of the two points.
I've tried with:
arw.setRect(QRectF(QPointF(0,0),QPointF(0,20)))
but it seems to change the precision and swaps the arrow head to the other end every new change. It seems to me this is not the way to go. Can anybody help me with this?
