[Qgis-developer] attributeMap vs. attributes

[Etienne Tourigny]

Another approach is to test qgis version and use appropriate API. Many
plugins do this. e.g. value tool

        if QGis.QGIS_VERSION_INT >= 10900:
            mapCanvasSrs = self.iface.mapCanvas().mapRenderer().destinationCrs()
        else:
            mapCanvasSrs = self.iface.mapCanvas().mapRenderer().destinationSrs()

I have updated the wiki page with that information.

Of course this may not be practical if there are many places to do
this. Other solution is to call a function which uses appropriate api
calls.
