How to approach Drag and Drop?

[geofmureithi-zz]

I want to create drag and drop similar to this one Codepen
According to #61, I can't use gtk and I am wondering where to start.

I think this should be achievable with a custom widget accepting a draggable set of items and containing a drop zone.

Once one of the items is clicked, you would draw it at the cursor position until it is dropped. If it is dropped in the drop zone, you could produce a Message containing the index of the dropped item.

The main limitation of this approach is that both draggable and drop zone will be part of the same widget and flexibility when it comes to styling/layout may be difficult. Right now, this is necessary in order to control drawing properly, as layers are not supported yet (see #30).

Interesting, let me see if I can get something done. Thanks.

The new PaneGrid widget (see #224) implements drag and drop with the approach I described in my previous comment.
