I'm trying to use interactjs with aurelia to have a system where dragging clones the dragged object, rather than moves it.
According to the interactjs FAQ (http://interactjs.io/docs/faq/#clone-target-draggable), this can be done using the move pointer event in interactjs. However, aurelia-interactjs doesn't appear to expose the interactjs pointer events.
Is there another way to accomplish this, beyond the method described in the interactjs FAQ?
Ok, I managed to answer my own question. There's an alternative method of creating the clone, outlined by Magnum79 here: https://github.com/taye/interact.js/issues/156
Using that instead of the interact move() one obviates the need to have pointer events supported in aurelia-interactjs. A slight modification for positioning, and translation into aurelia yields:
dragStart(event) {
event = event.detail;
if (!event.target.dragOrigin) {
var clone = event.target.cloneNode(true);
clone.dragOrigin = event.target;
event.interaction.element = clone;
event.interaction.dragging = false;
var dragTarget = clone;
document.body.appendChild(clone);
var r = event.target.getBoundingClientRect();
clone.style.position = 'absolute';
clone.style.left = r.left + 'px';
clone.style.top = r.top + 'px';
} else {
dragTarget = event.target;
}
}
Which works like a charm.
