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

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.
