I think there was/is more: when the drop happens outside of any accepting node, the drag image scuttles back to the original place, with no way to disable that behavior.
This made the DnD unsuitable for me in the context of a docking framework, where the user expects a new window to be created with the dragged content. Also, it is impossible to control the scaling of the drag image, for instance, to disable the scaling altogether. -andy From: openjfx-dev <openjfx-dev-r...@openjdk.org> on behalf of John Hendrikx <john.hendr...@gmail.com> Date: Monday, August 18, 2025 at 02:37 To: Nir Lisker <nlis...@gmail.com> Cc: openjfx-dev@openjdk.org <openjfx-dev@openjdk.org> Subject: Re: Full press-drag-release done event Yeah, that sounds reasonable, showing the source of the drag is quite useful I would think, and you can only do that if you can unhighlight it at the right time. --John On 18/08/2025 09:13, Nir Lisker wrote: (Replying to the mailing list this time :) ) I have nodes that need to be dragged onto other nodes (in the same application) and are highlighted for the full drag-press-release duration, with an additional state change about the "selected" node. If they are dropped on a target that can accept them, the cleanup can be done when the drop is done, but if they are dropped outside of the application or on a node that can't accept them, the process never finishes. There are workarounds, but DnD shows that it can be much easier to do with the additional event.
