Hello!I'm very new to creating script tools, and I recently started working with the Tool Validator. I'd like the users of my script tool to be able to select their input parameters from a dropdown list showing current map layers that match the input type (for example, if the input is specified as the type "Feature Class", a list of feature classes in the current map document would appear as options in a dropdown list). Most of the ArcGIS tools automatically do this. Although it doesn't work, this is what I have come up with so far (input 1 is a Feature Class, and input 2 is a Raster):def initializeParameters(self):
mxd = arcpy.mapping.MapDocument("CURRENT")
featureLayerList = []
rasterLayerList = []
for lyr in arcpy.mapping.ListLayers(mxd):
if lyr.isFeatureLayer == True:
featureLayerList.append(lyr.name)
elif lyr.isRasterLayer == True:
rasterLayerList.append(lyr.name)
self.params[1].filter.list = featureLayerList
self.params[2].filter.list = rasterLayerList
return
I would greatly appreciate any advice!Ride the lightning,Amy---www.wolfmapper.com
