[Octave-bug-tracker] [bug #37795] FLTK - cannot close figure

[Mike Miller]

Update of bug #37795 (project octave):

                 Release:                   3.6.3 => dev

Follow-up Comment #5:

I can reproduce the problems described here but only if running Octave with
--no-line-editing. All of the symptoms described in this report seem to agree
with no readline support, either disabled at runtime or not compiled in to
Octave to begin with:

* unresponsiveness of the FLTK plot window
* unable to close the plot window
* same behavior when running from emacs, since emacs inferior mode adds the
--no-line-editing option

Basically FLTK requires the readline event loop be running. If Octave is not
compiled with readline or if it's disabled at runtime, the event loop doesn't
run and FLTK won't work.

That's the extent of my knowledge, is there any conceivable way around this?
Do we prevent FLTK from being set as the active toolkit when readline is not
enabled?
