How can we detect the click on the arrow head ? #269

I want to listen when the arrow head of the edge is clicked or when the arrow is moved but not swapped, so that i can perform the required function.

That feature is not yet supported. Please feel free to create a PR if you would like to add it. I would suggest following the isArrowClicked function in graph-view.js on line 944. You may choose to add the code in the calling function or somewhere else, however that isArrowClicked function should be part of the solution.
