Dynamic drag image during drag

[ddenev]

Hi,

Is is possible to have a dynamic drag image (one that can be changed during the drag operation)?

Here is an example of what I mean - https://marcojakob.github.io/dart-dnd/custom_avatar/

Best regards.

That is something I had not envisioned. The drag image may only be defined using a slot on Drop components. But I suppose you could use the dragenter, dragleave and dragover events to do this yourself, or use the computed provided by the DragAwareMixin. But it isn't convenient.

Yes but the idea here is a little bit different - if you noticed in the example above, the image changes during the drag move (I guess based on distance from source) and does not depend on the drop zone.

So I guess this could be a nice enhancement indeed.

No what I mean is to create the drag images yourself, animate them and swap between them, just like I do. But it's not convenient.

What I should do is allowing several drag-image slots like drag-image:a, drag-image:b, and so on...and allow to user to supply a function that returns which one should be currently in use (a or b or...).
