How do you apply a QgsExpression to a Label ?
I can do it in QGIS with this simple expression concat('N:' ,round(Value,0),'\n','Yield:' ,round(Value 2,0))
N: 65
Yield: 40
How do I do it in PyQGIS ? I see a getLabelExpression but no setLabelExpression
This works but I want but only for the field name
crap = QgsVectorLayer("D:/data.shp", "data", "ogr") QgsMapLayerRegistry.instance().addMapLayer(crap) palyr = QgsPalLayerSettings() palyr.readFromLayer(crap) palyr.enabled = True palyr.fieldName = 'Name' palyr.placement= QgsPalLayerSettings.OverPoint palyr.setDataDefinedProperty(QgsPalLayerSettings.Size,True,True,'8','') palyr.writeToLayer(crap)
