Get Selected Layer

TedChapin — Wed, 24 Apr 2013 12:03:37 GMT

I'm looking for a way to get the currently selected layer(s) from the TOC. arcpy.mapping.ListLayers() returns all layers in the data frame. I only want the ones the user has selected. Does anyone know how to do this?

As of 10.1 you can return a handle on a single selected layer, have a look at this thread.

How about:

#prints a list of the selected layers in the TOC along with the number of selected records
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0]
for lyr in arcpy.mapping.ListLayers(df):
   selectedCount = len([int(fid) for fid in arcpy.Describe(lyr).fidset.split(";") if fid != ''])
   if selectedCount > 0:
      print "The " + str(lyr) + " layer has " + str(selectedCount) + " records selected..."
