mypLayer->setCustomProperty("labeling", "pal");
    mypLayer->setCustomProperty("labeling/enabled", "True");
    mypLayer->setCustomProperty("labeling/fontFamily", "Cantarell");
    mypLayer->setCustomProperty("labeling/fontSize", "11");
    mypLayer->setCustomProperty("labeling/fieldName", "DRVAL1");
    mypLayer->setCustomProperty("labeling/placement", "1");

Didn't work for me with QGIS 2.14. At the same time this code works fine at Python console in QGIS Desktop application on CentOS 7.5 x64.

layer = iface.activeLayer()
layer.setCustomProperty("labeling", "pal")
layer.setCustomProperty("labeling/enabled", True)
layer.setCustomProperty("labeling/fontFamily", "Cantarell")
layer.setCustomProperty("labeling/fontSize", "11")
layer.setCustomProperty("labeling/fieldName", "DRVAL1")
layer.setCustomProperty("labeling/placement", "1")

Any suggestions?

  • Have you tried just using the boolean value for True excluding the quotes (i.e. mypLayer->setCustomProperty("labeling/enabled", true);? – Joseph Feb 8 '19 at 12:09
  • yes, I've tried to use true, TRUE, "true", "TRUE" with the same result. – Wolf Schulz Feb 8 '19 at 12:24

That was just a problem with layer. Code works as expected.
