Is it safe to connect a signal to a slot in an object that might be deleted by the time the signal is emitted?
I.e I want the signal to be ignored with no error message if the receiver has fallen off its perch and is pushing up the daisies.

Re: signal to dead object
Unless the object gets deleted as a result of emitting a signal (i.e. in a slot connected to its own signal).
Your biological and technological distinctiveness will be added to our own. Resistance is futile.
Please ask Qt related questions on the forum and not using private messages or visitor messages.
