Hi Hua Jie,
What you did is really nice! You could contribute this by making an
example out of it :
* fork openlayers 'master' branch and clone
* create new .html and .js in the 'examples' directory to create an
example out of it, using the same files the other examples do.
* add/commit/push/pull request
Even though the class you created wouldn't be part of the actual
core, it would still demonstrate how to assemble OpenLayers core
components to achieve this.
Regards,
Alexandre

Hi All
Thanks for all the help.
I draft a version first. Not sure how to contribute to the lib.

Hi,
you can make a feature whose geometry is a
GeometryCollection, this collection can contain a line and
a point grouped into one geometry then you can use the
below mentioned style to draw an arrow with your line
{
strokeColor: "#00688B",
fillColor: "#00688B",
fillOpacity : 1.0,
strokeWidth: 2,
strokeOpacity : 0.9,
pointRadius: 6,
graphicName :"triangle",
rotation :angle
}
remember to compute the angle before setting this .. you
should be able to calculate angle between start and end
point of your line segment.. and also the position of
point geometry which will be drawn as triage with given
rotation angle..
Hope I got my point through..
regards,
Imran

Hi Hua Jie,
You could try to define your own arrow symbol.
There's one defined [here], see line 1 :
OpenLayers.Renderer.symbol.arrow = [0,2, 1,0, 2,2,
1,0, 0,2]
I haven't tried it, but it could do the trick.
HTH,
