Hi Benoît,
would you mind sharing your hole script as reference for others?
I think you touched a common problem which isn't covered with built-in
functions yet, and not everyone is gifted with profound coding abilities
in python (like me ;) )
Cheers
Bernd

I eventually managed to solve my problem. In case somebody encounters
the same or a similar one, I provide my solution: I used a >Python

Instead of using "legend.setLayerVisible(layer, True)", I played with
symbols:
layers[2*g].rendererV2().symbol().setWidth(2)
layers[2*g].rendererV2().symbol().setAlpha(1)
There were others problems in my code but the main difficulty lied
there. Symbols can be updated during Python scripts and it >perfectly
meets my needs.
