in thread How to draw a curved arrow in perl Tk canvas ?

Thanks a lot....this solved my problem. I would also require to draw a self loop for a node in a canvas,i.e, an edge that will start and end in the same node showing a small loop. Is there some way around preferably using the createLine function... Precisely what I require is given a point ($x,$y), How to draw a small circular loop around it using createLine function. Any help would be highly appreciated...Thanks again for the help provided so far..

    Isn't that simply a circle? See Tk::Canvas createOval().

      Not actually...I wanted using the createLine....but indeed it was simple..I figured it out just after posting :)
      my ($x1,$y1); my $r = 50; # radius my @new_coords = ($x1,$x2,$x1-$r,$x2+$r,$x1,$x2+(2*$r),$x1+$r,$x2+$r,$ +x1,$x2+8); $id = $can->createLine(@new_coords);
      Thanks for the help anyways...
