Creating polyline using mouse clicks with Python Addin tool?

Question

Can somebody tell me how to create a line geometry by mouse click with python addin?

I am using below code in python addin tool.

class ToolClass8(object):
"""Implementation for Testmsg_addin.tool (Tool)"""
def __init__(self):
 self.enabled = True
 self.cursor = 3 
 self.shape = "Line" 
def onLine(self, line_geometry):
 NewL = "NewL"
 cur = arcpy.da.InsertCursor(NewL, ["SHAPE@"])
 array = arcpy.Array()
 part = line_geometry.getPart(0)
 for pt in part:
 array.add(pt) 
 cur.insertRow(arcpy.Polyline(array))

which throws the error:

cur.insertRow(arcpy.Polyline(array)) TypeError: argument must be sequence of values

Can somebody help me with the code?

Answer 1

If you read the help file for a Tool Class the onLine() method returns a polyline object:

def onLine(self, line_geometry):
 cur = arcpy.da.InsertCursor("NewL", ["SHAPE@"])
 cur.insertRow([line_geometry])

• PolyGeo: @AkhilKumar It's expecting a list of strings (field names or tokens), and my answer provided only a string with a token, whereas this provides a list of one string.
