There are cases when deleteLater() may be unnecessary. So it is a
However, deleting an object from a slot is a BAD idea: you're deleting an
object that is in use. I am saying that from the library developer point
of view. Think of the following code:
d->something = true
d->somethingElse = true;
If the slot connected to "finished" deleted the object, this code will
either crash or cause memory corruption.
So, as a library developer, I try to avoid doing anything to the object
after emitting any signals. But sometimes it isn't possible.
As for deleteLater(), don't think it'll magically solve all problems.
