[Octave-bug-tracker] [bug #44330] Qt toolkit segmentation fault when figure opened, closed, and opened again

[John W. Eaton]

Follow-up Comment #9, bug #44330 (project octave):

Since this works with FLTK, which only processes events when Octave is
otherwise idle (or in a safe spot to do so), I think my initial change may
actually be in the wrong direction.  I think we may need to limit what the Qt
toolkit can do unless Octave is waiting for input.  However, unlike FLTK, the
Qt widget thing is running in a separate thread, so it could possibly handle
events continuously while readline is active, not just when readline calls the
input_event_hook function.
