It took some effort :-) I'm in an unusual position because the selection of objects in Navigator's live display *really* messes with the traditional drag/drop messages and the selection within the field I use for the list display. I tried very hard to work around that many years back, but finally gave up, and used a set of drag and drop code that just depended on mouseDown, mouseMove, mouseUp, and mouseRelease. I think it was from Scott Rossi originally, but I'm not sure.
The new code builds on that, and uses two stacks with their blendlevel set to something like 80: one to represent the dragged objects, one to highlight the targets. Despite the mouse leaving the list and being over the drag stack, the mouseMove messages still go to the list field. So I dispatch a message from there to the drag stack, to keep things clean in the list field. There's a lot of translation from local to screen coordinates. All of the code is available in Navigator, or at the Navigator GitHub repository <https://github.com/gcanyon/navigator>. It's not particularly clean at present because I built it all wrong the first time, and then re-built it. When I go back in I'll cut away the vestigial code. There is still a ton to do: 1. Dragging from stacks into Navigator. 2. Dragging from Navigator into another Navigator. 3. Alignment to existing controls in stacks I drag into -- this is why I started the project in the first place. If you have any questions, let me know. gc On Mon, Feb 12, 2018 at 7:50 AM, Bob Sneidar via use-livecode < use-livecode@lists.runrev.com> wrote: > Sure like to know how you do that.
