The setLayerInsertionPoint() with the QgsProject.instance().layerTreeRoot() object is deprecated. The documentation says:
since QGIS 3.10 use setLayerInsertionPoint( const InsertionPoint &insertionPoint ) instead
but I can find no example of how to implement this update. My current code is as follows:
QgsProject.instance().layerTreeRegistryBridge().setLayerInsertionPoint(QgsProject.instance().layerTreeRoot(), 0)
It seems the only change is the first argument. How should I update the statement to comply with current requirements?
QgsProject.instance().layerTreeRegistryBridge().setLayerInsertionPoint([what_goes_here?], 0)
I have not actually tested this but the following should work:
root_group = QgsProject.instance().layerTreeRoot()
insertion_point = QgsLayerTreeRegistryBridge.InsertionPoint(root_group, 0)
QgsProject.instance().layerTreeRegistryBridge().setInsertionPoint(insertion_point)
To check, the line:
print(insertion_point)
returns:
<qgis._core.QgsLayerTreeRegistryBridge.InsertionPoint object at 0x000001DAE4116678>
See:
