Hi list
When loading a vector layer via Python, is there a way to get a hold of the
error message for when the loading fails?
I can check if the layer is valid or not, but I'd like to get a description
of the error. I see the error on the QGIS log panel, so I'm hoping it is
possible to access it
But now I see that it is there and I was the one looking at the wrong
place.
Cheers

Hi Richard
You can add widgets to a specific layer if you know the widget provider's
id. It is simply a matter of setting up the relevant custom properties.
Take a look at the code in the PR you linked, more specifically here:

Hi all
I have a working python code snippet that enables updating a WMS layer with

It basically manipulates the raster provider's `dataSourceUri` property,
