Displaying the cursor inside an overlay?

Displaying the cursor inside an overlay?

[Po Lu]

Is there a way to display the (bar) cursor at some position inside an
overlay's before or after string?

Thanks.

Use the 'cursor' property on the string.  (This doesn't depend on the
cursor's shape, so it should work with a bar cursor as it does with a
block cursor.)

Thanks, I must've missed that.  I see it in the index of the Lisp
reference manual now.

Yes, but judging by the code you installed, I'm not sure you used the
property correctly.  It's supposed to be on a single character, and
AFAIU your use case its value should be t, not a number.

(This discussion should probably move to emacs-devel.)

Ahh, thanks, I understand now.  Dunno why it seemed to work: probably my
input method is set up in some queer way.
