Hi experts I tried to create a function for my Tkinter button 1 by which to be able to Select Features from a layer of my current map. Something is missing in my codes. They don't work. What do I need to add to these codes to work as an interactive selection tool. I need to click on the map then drag and then release and then a rectangle to be created and finally the features to be selected. Please have a look on my codes and help me. Best regards. Babak
def button1Click(self, selection):
mxd=arcpy.mapping.MapDocument("CURRENT")
# This is an empty polygon shape file.
extent = "extent_shapefile"
# Set the workspace
#
env.workspace = mxd
# these codes are for selecting a layer from listbox
index = self.listbox.curselection()
label = self.listbox.get(index)
# Local variables: a layer from listbox. It is fine
layer = label
# Data ferame is the current map
df = arcpy.mapping.ListDataFrames(mxd)[0]
# Create a search cursor from layer
#
# Create an Array object.
#The DataFrame extent object is converted into a polygon feature so it can be used with the SelectLayerByLocation function.
dfAsFeature = arcpy.Polygon(arcpy.Array([df.extent.lowerLeft, df.extent.lowerRight, df.extent.upperRight, df.extent.upperLeft]),df.spatialReference)
arcpy.SelectLayerByLocation_management(layer, "INTERSECT", dfAsFeature, "", "NEW_SELECTION")
