[Octave-bug-tracker] [bug #50025] Octave window freezes when I quit Octave GUI

[Dan Sebald]

Follow-up Comment #19, bug #50025 (project octave):

Oh yeah, you're right.  I forgot that the signal type can be altered when
making the Qt connection.  The wait of quit/wait construct effectively creates
a lock (I think, but haven't explored).  Is there any difference between the
two constructs?  I'm not sure.  Nonetheless, the quit/wait construct is an
example as shown in the Qt documentation, so it's got that going for it.  

I'm open to the blocking queued signal approach, though, but at the same time
prefer not experimenting too much with something that seems to work, at least
for now, in an otherwise historically fragile exit process.  If/when the exit
is overhauled to be more robust is a better time for experimenting.
