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

[Pantxo Diribarne]

Follow-up Comment #18, bug #50025 (project octave):

@Dan:

>> The signal/slot connection doesn't have a means for waiting

I don't know if it is relevant here since since I did not look into this at
all, but ther *is* a way to have the signal function return only when the slot
has returned. The connection must be made in queud mode:
 connect (signal,..., Qt::BlockingQueuedConnection)

There is a requirement though, the signaling thread is then locked until the
slot thread has returned: it means that the slot thread can't request some
operation to be done in the signal thread because it would lead to a dead
lock.
