Thanks Anita - easier than I thought.
Apparently one has to refresh the canvas after setting the
subsetString.
Is that how you do it in Time Manager?
Thanks,
Andreas

Hi Andreas,
layer.setSubsetString( subsetString ) seems the way to go. At least
that's what I use in Time Manager ;)
Best wishes,

Hi,
For an existing layer I would like to add/change/remove the WHERE
filter by script - the same that one would normally set by the query
builder.
Do I need to change the QgsDataSourceURI() of that QgsVectorLayer
and then reload it or is there an easier/more elegant way to change
the filter of an existing layer?
Thanks if you have any ideas or even sample code on how to achieve
this.
Andreas
