events / dragged not working

[yankeeinlondon]

When I used the d3-drag/drag function in conjunction with d3-selection/event it would appear all events are not getting through to d3. I had a suspicion that the Ember component was swallowing up these events so I changed over to a tagless component figuring I'd have greater control of the events on the SVG/Canvas element. Sadly that didn't seem to help. Any ideas?

Code here: https://github.com/ksnyde/d3-fun/blob/master/app/components/circle-dragging.js#L79-L84

P.S. I have really enjoyed using this addon to get started with d3 in Ember. Great work. I actually will likely send you a PR which just adds a few more examples of charts you can build with this addon (if you're amendable). I think it will make your work more approachable to have the dummy app have a variety of examples working for people to engage with

I haven't tried events with canvas, so can't really offer much advice there. Ember doesn't swallow events, instead relies on them bubbling up to the document level to catch them in global event handlers, then delegate them to any components which register handlers. So what's more likely is that your event handlers aren't attaching correctly, which might require something different with canvas.

Hmmm. At the moment I’m just transcribing examples on Bl.ocks using your add-on so my approach is a proven approach. Must be something I’m doing in translation.

@ksnyde did you resolve this?

I didn't but largely due to lack of bandwidth. If you want to close it I can reopen when I come back to this in a week or so.
