Just check for the layer type to only list raster layers
def initLayerCombobox(self,combobox, default):
reg = QgsMapLayerRegistry.instance()
for ( key, layer ) in reg.mapLayers().iteritems():
combobox.addItem(
Hi Matthias,
thanks for your help. I guess it is similar to what I found?
def getRasterLayersNames():
layerList = []
layerMap = QgsMapLayerRegistry.instance().mapLayers()
for name, layer in layerMap.iteritems():

self.setupUi(self)
self.initLayerCombobox( self.ui.InRastA, 'key_of_default_layer' )
def initLayerCombobox(self,combobox, default):
combobox.clear()
reg =
Hi Matthias,
that works. Thanks a lot!
