I am using rubber band in Python plugin: self.rb = QgsRubberBand(self.canvas, QGis.Polygon) and on mouse move self.rb.addPoint( point, update )
It works well on most systems only for Win7/32bit (QGIS 2.0.1, Python 2.7.4) it was reported that it fails with "RuntimeError: underlying C/C++ object has been deleted" I see that ownership of rubber band is passed to map canvas QgsRubberBand( QgsMapCanvas* mapCanvas /TransferThis/, QGis::GeometryType geometryType = QGis::Line ); that is OK, but QgsMapCanvas should not delete QGraphicsItem until it is destructed. So how can the QgsRubberBand be deleted before QGIS is closed?
