Has anyone ever worked on being able to drag files and regions from Emacs
to another Mac application?

I'd like to be able to:

1. Drag files from Dired to an editable window in another application, e.g.
Chrome.

2. Select a region and have a mouse key binding that would drag it to the
other application.

Thanks for any pointers.

Bob

`mouse-drag-and-drop-region' (from 26) moves region within a frame.

Excellent.  Thanks for the tip.  Some things I'm working on now will
probably allow this to be extended across frames.

I wonder why it doesn't work to drop the text onto other applications.

It does, but the application you drag-n-drop into should support that.

On a Mac:

I highlight text in Evernote and drag it into a Chrome Gmail composition
window.  It drops right in without a problem.

I enable text drag-n-drop in Emacs 27 and highlight some text to try to
drag it to the same Chrome window.  A yellow rectangle of text starts to
drag but freezes right as the mouse pointer leaves the Emacs frame, so I
can't drag it any further.

Maybe I was confused, and we only support drag-n-drop _into_ Emacs.

Probably because there's no standard protocol to drag and drop anything
but files between different applications.

Maybe not for every window system but on MacOS there is and many
applications accept dragged text directly:

https://developer.apple.com/documentation/uikit/drag_and_drop/making_a_view_into_a_drag_source
 - source info


https://stackoverflow.com/questions/27420016/osx-drag-and-drop-text-not-file-to-app-dock-icon

- destination info

So this could be an addition to the macOS-specific drag-n-drop support.

For now `mouse-drag-and-drop-region' does nothing when
(event-end (read-event)) is toward out of the current frame.

I think the first step is to revise `mouse-drag-and-drop-region' to let
it drag text to a different frame.

So I have fixed that as you can see in my prior message.  Now what must be
done to allow Emacs to drop the text onto another Mac application that
accepts dropped text?
