How can I get the selected layers in QGIS 3 with pyqgis?
selectedLayers = iface.legendInterface().selectedLayers()
as suggested in How to get programmatically selected layers from the QGIS legend?, but it seems that there is an API breaking change
QgsLegendInterface was removed. It was replaced by layer tree API (QgsLayerTreeNode class and others). Methods that deal with custom actions in main window's layer tree context menu were moved to QgisInterface:
I then tried:
selectedLayers = QgsProject.instance().layerTreeRoot().selectedLayers()
but I get an error about:
AttributeError: 'QgsLayerTree' object has no attribute 'selectedLayers'
What's the correct way to get the selected layers in QGIS3?
