Run Measure after drawing a Line

[JSmith-2]

I'm new to writing Macros, and I'm trying to write one that will run Measure each time I draw a line.  So far I have it so that Measure is running continuously while I draw the line, then stops measuring after I stop drawing.  

Is there a way I can make Measure only run after the mouse is released?  

Thanks for any advice you can give.

Change the macro so it runs the Measure command when the user lets up  
the mouse button. Here is a macro tool that does this.

-wayne

  macro "Measure Line Tool -C00bL1de0L1ee1" {
         getCursorLoc(x, y, z, flags);
         xstart = x; ystart = y;
         x2=x; y2=y;
         while (true) {
             getCursorLoc(x, y, z, flags);
             if (flags&16==0) {
                  run("Measure");
                  exit;
             }
             if (x!=x2 || y!=y2)
                 makeLine(xstart, ystart, x, y);
             x2=x; y2=y;
             wait(10);
         };
     }

Thank you SO much!  This is exactly what I was trying to do!  :)

Sometimes the lines I'm measuring are a bit curved, is it possible to replace the line tool with the freehand line tool in this macro?
