[QGIS-Developer] refresh conditional formatting full row after feature attribut update

[Häfliger Guido]

Hello

If I start the edit session manually and edit the attribute, the conditional formatting full row rule are applied immediately, even before saving.

It seems like the refresh of the conditional formatting full row rule ignore the first or last feature-id of the modified features if the attributes are modified by python code.

I tried to find an API-method which forces the refresh of the conditional formatting row rules but I didn't find anything which works

Best regards
Guido

If selected_features contains several features, the conditional formatting works except for the first selected feature, so it is not correct.

Sounds like a bug to me -- can you reproduce if you make changes from
the QGIS interface itself and without the python code?

Nyall



or do I have to use another method to update the attributes? Exist a
workaround to force the refresh of conditional formatting full row
rules on a opened attribute table?
