[OpenLayers-Users] Rotate the line geometry with arrow - using rotation style?

[mikeluz]

Hi there

First of all thank you very much for the interest and for giving me some
idea how to do that. Maybe someone will have this same problem, so I will
write what I came up with. I think that there were 2 possible solutions for
this problem:
1. The one that was mentioned by *Jørgen S. Nicolaysen*
Actually the style definition was ok, and everything was ready to use. The
only problem was that during rotation the "angle" attribute was not changed.
I think it could be done with this code (not 100% working code, just an
idea):
/                var orginalFunction = myContorls.modify.dragControl.onDrag;
		myContorls.modify.dragControl.onComplete = function (feature, pixel){
			orginalFunction.apply(this,arguments);
                        feature.attributes.angle = 180 // (feature is the
arrow!!!!)
                        feature.layer.drawFeature(features)

                }/
I really think that this should work. I have not tested it, I just had the
idea for it... For my problem I choose second approach

2. This was *Arnd Wippermann* idea. I have not seen this example before, and
I was really surprised how nice this idea was. Create line and polygon in
shape of an Arrowhead :) I mean how simple is that :)  I used it and it
works really great. Any code I guess is not needed. Everything is in that
example that Arnd shown me. 

BTW. I find it really annoying that there was a solution online, but I was
not able to find it :( OL should put some links to their example page to
some other example that are available online. That would help a lot... 

Thank you one more time!

Regards,
Pawel
