Measuring distance in ArcGlobe using Python AddIn

Question

I want to make a Python script that will calculate the distance of the line I drew and output it in a special form, but I can't figure out what I'm doing wrong.

import arcpy
import pythonaddins

class ToolClass2(object):
    """Implementation for probn_addin.tool (Tool)"""
    def __init__(self):
        self.enabled = True
        self.shape = "Line" # Can set to "Line", "Circle" or "Rectangle" for interactive shape drawing and to activate the onLine/Polygon/Circle event sinks.
    def onMouseDown(self, x, y, button, shift):
        pass
    def onMouseDownMap(self, x, y, button, shift):
        print(x,y)
        return(x,y)
    def onMouseUp(self, x, y, button, shift):
        pass
    def onMouseUpMap(self, x, y, button, shift):
        print(x,y)
        return(x,y)
    def onMouseMove(self, x, y, button, shift):
        pass
    def onMouseMoveMap(self, x, y, button, shift):
        pass
    def onDblClick(self):
        pass
    def onKeyDown(self, keycode, shift):
        pass
    def onKeyUp(self, keycode, shift):
        pass
    def deactivate(self):
        pass
    def onCircle(self, circle_geometry):
        pass
    def onLine(self, line_geometry):
        onMouseDownMap(x1,y1)
        onMouseUpMap(x2,y2)
        dist = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
        message = "Your lenght:" + str(dist)
        pythonaddins.MessageBox(message, "Ruler")
    def onRectangle(self, rectangle_geometry):
        pass

Answer 1

Try replacing the following lines of code:

def onLine(self, line_geometry):
    #onMouseDownMap(x1,y1)
    #onMouseUpMap(x2,y2)
    #dist = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
    message = "Your length: " + str(line_geometry.length)
    pythonaddins.MessageBox(message, "Ruler",0)

This will return the length of the line which may have more than two vertices, your code would have returned the straight line distance between the end vertices, if it was working.
