The drag behavior should support pointer events.

[stnor]

Hi,
Dragstart, Dragend and Drag events doesn't seem to fire on Microsoft Edge (the new browser in Windows 10) on a Microsoft Surface 3 Pro touch device.

Code works great on IE9-IE11. Does d3 support pointer-events?

If you need more information or help testing, I'd be glad to assist.

Thanks!

This works on IE11 and Chrome but not Edge.

   drag = d3.behavior.drag()
                    .on("dragstart", function(d, i) {
                        console.log("got it")

I also added a console.log in d3 3.5.6 (which prints):

  d3.behavior.drag = function() {
    var event = d3_eventDispatch(drag, "drag", "dragstart", "dragend"), origin = null, mousedown = dragstart(d3_noop, d3.mouse, d3_behavior_dragMouseSubject, "mousemove", "mouseup"), touchstart = dragstart(d3_behavior_dragTouchId, d3.touch, d3_behavior_dragTouchSubject, "touchmove", "touchend");
    //var pointerdown = dragstart(d3_noop, d3.touch, d3_window, "pointermove", "pointerdown")
    function drag() {
      this.on("mousedown.drag", mousedown).on("touchstart.drag", touchstart) //.on("pointerdown.drag", pointerdown);
    }
    function dragstart(id, position, subject, move, end) {
      return function() {
        console.log("*** DRAGGING")
        var that = this, target = d3.event.target, parent = that.parentNode, dispatch = event.of(that, arguments), dragged = 0, dragId = id(), dragName = ".drag" + (dragId == null ? "" : "-" + dragId), dragOffset, dragSubject = d3.select(subject()).on(move + dragName, moved).on(end + dragName, ended), dragRestore = d3_event_dragSuppress(), position0 = position(parent, dragId);
        if (origin) {
          dragOffset = origin.apply(that, arguments);
          dragOffset = [ dragOffset.x - position0[0], dragOffset.y - position0[1] ];
        } else {
          dragOffset = [ 0, 0 ];

My code works now on Edge both in d3 v3 and v4. Tested on Edge 38.14393
