Labeling

Usual labels

myLayerText = QgsTextFormat()
myLayerText.setFont(QFont('Verdana', 8))
myLayerText.setSize(8)
 
myLayerLabelSettings.setFormat(myLayerText)
 
myLayerSettings = QgsVectorLayerSimpleLabeling(myLayerLabelSettings)
myLayers.setLabeling(myLayerSettings)
myLayers.setLabelsEnabled(True)
 
myLayers.triggerRepaint()
iface.mapCanvas().refresh()
