[Qgis-developer] Handling deprecation of QgsMapCanvas.mapRenderer()

[Tom Chadwin]

I see that QgsMapCanvas.mapRenderer() is deprecated. We are currently using it as follows:

crsSrc = qgis.utils.iface.mapCanvas().mapRenderer().destinationCrs()

If I read the documentation correctly, the new way of achieving this is:

crsSrc = qgis.utils.iface.mapCanvas().mapSettings().destinationCrs()

Is that correct? If so (as a QGIS plugin and Python beginner) what is the best way to handle the deprecation and maintain backwards compatibility, given that QgsMapCanvas.mapRenderer() is only in 2.4+?

Thanks

Tom
