Re^4: 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..

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);` [download] Thanks for the help anyways...
