How to add layer/raster with specific position in the QGIS layer list?

Question

I use addRasterLayer(rast,'Name') but this adds the raster to the top. It is possible to set position when I add raster at once? Is it possible??

Answer 1

By using the new Layer tree (aka legend or Toc) added by Martin Dobias since QGIS v.2.4, you can load a raster layer to any position of the ToC following these steps:

1. Get a reference of the layer tree

   root = QgsProject.instance().layerTreeRoot()

2. Create the raster layer object

   from PyQt4.QtCore import QFileInfo fileName = "/path/to/raster/file.tif" fileInfo = QFileInfo(fileName) baseName = fileInfo.baseName() mylayer = QgsRasterLayer(fileName, baseName)

3. Add the layer to the QGIS Map Layer Registry (the second argument must be set to False for you to specify a custom position in step 4.)

   QgsMapLayerRegistry.instance().addMapLayer(mylayer, False)

4. Insert the layer in the third position of the ToC

   root.insertLayer(2, mylayer)

Answer 2

I will need to look into that, but you could try to add the layer and than change the order afterwards, if you want to use python anyway. Check out this other thread about changing the order of layers in the TOC for hints.
