[Qgis-developer] Access to the value in a Relation reference wiget

[Matthias Kuhn]

You try get a QgsRelationReferenceWidget (in qgis.gui) (not sure though
if specifying this explicitly makes any difference in python though, it
should determine the real type anyway).

The methods you are looking for are then

setForeignKey()
http://qgis.org/api/classQgsRelationReferenceWidget.html#a2e9fb74545d2bb4b697a88ca4e434600

and

foreignKey()
http://qgis.org/api/classQgsRelationReferenceWidget.html#af1765af438f3dd4e642334a338a03ca4

Best,
Matthias
