That is the keyword for the only existing work-around
"path".
The only current way to retrieve user coordinates on an image
from a Python script is to ask the user to draw a Path
(vector) with the paths tool beforehand (or at least,
before pressing the script's "ok" button) and then
use the vectors pdb calls to retrieve those coordinates.

There is no way to retrieve information in an interactive
way - but for a bad hack: letting your plug-in
running and retrieve coordinates from the active paths
by pooling it at each few tenths of a second.

When transitioning to GEGL painting, which
is not scheduled to happen to gimp 2.10 -
maybe it will be possible to use arbitrary GEGL meta-operations
to respond to GIMP events. My idea is that it should be
possible to create such meta-operations from Python
or other language bindings - but this is loong downroad,
and as far as I think, had not been discussed among
the developers in any detail.
