[Qgis-developer] Field visibility in Python

[Tom Chadwin]

Hi Matthias

Many thanks for this. It's not working for me quite yet:

AttributeError: 'QgsVectorLayer' object has no attribute 'editorWidgetV2ByName'

Python version:
2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]

QGIS version:
2.2.0-Valmiera Valmiera, c3a2817

Any ideas?

Tom
