[Qgis-developer] Field visibility in Python

[Tom Chadwin]

Apologies for cross-post from qgis-user - I thought -developer only dealt with QGIS core, rather than also with plugin development.

How do I determine in Python whether each field is hidden? I can't get editType() to work (and know it is deprecated). Does anyone have an example of this using editorWidgetV2Config()? I'm not getting it right:

canvas = qgis.utils.iface.mapCanvas()
allLayers = canvas.layers()
for i in allLayers:
        fields = i.pendingFields()
        field_names = [field.name() for field in fields]
        for field in field_names:
                print(i.editorWidgetV2Config(fields.indexFromName(str(field))))

This just gives me lots of {}, suggesting perhaps that I am not setting the field index for editorWidgetV2Config() correctly. fields.indexFromName(str(field)) works as the *attribute* index for attributeDisplayName(), but the docs say attributeDisplayName(attributeIndex), while they say editorWidgetV2Config(fieldIdx). What's the difference between attributeIndex and fieldIdx?

Thanks

Tom
