[Interest] Good way to track down "QCoreApplication::postEvent: Unexpected null receiver"

[Bob Hood]

I'm getting this warning/error, but it's pretty nebulous in terms of where
exactly it is occurring. Is there some kind of debug switch I can enable to
get move verbose output when this occurs, perhaps something that would help me
pinpoint the culprit?

Hi,

That usually occurs when you are calling deleteLater on a null QObject.

First thing I'd check are delete and deleteLater statements of QObject derived class.

Cheers

Ah, excellent. That at least lets me know where to focus my attention.

Thank you, Samuel.

Run with QT_FATAL_WARNINGS=1? Add a breakpoint on the qWarning
statement in question inside Qt?

Good point, Giuseppe. I did not know about that variable. I'll try that and
see if it helps.

Thanks so much.
