Bug report #13152

QgsRubberBand not displaying holes in geometry

Added by Luca Congedo almost 9 years ago. Updated almost 9 years ago.

Affected QGIS version:2.10.0 Regression?:No
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:
Crashes QGIS or corrupts data:No Copied to github as #:21215


Adding a geometry from a shapefile to QgsRubberBand does not displays holes in the original geometry (holes are filled).

For testing, try the following code with the attached shapefile.

from qgis.core import *
from qgis.gui import * 
canvas = qgis.utils.iface.mapCanvas()
cLayer = canvas.currentLayer()
rbbrBndPol = QgsRubberBand(canvas, 2)
f = QgsFeature()
fR = QgsFeatureRequest().setFilterFid(0)
f = cLayer.getFeatures(fR)
f = f.next()
rbbrBndPol.addGeometry(f.geometry(), cLayer)

Thank you

This is by design. The rubberband is the kind of tool you would use to draw a hole into an existing polygon.
You can use QgsHighlight instead.
