C++/Qt5 - Signals with no receiver, what happens?

[jimbo]

Hello,

Suppose I have a mainwindow emitting signals to a dialog.
What happens if there is no dialog active at the time the sinals are sent?
Do the signals just vanish or is memory used and left floating (leak).
This has not happend, its just a question.

Signals are supplied to connected recivers. When receiver is deleted all signals connected to them are auto disconnected. So when You send a signal without receivers nothing happens.

Hello Lesiok,

Thanks for your response.
So not a problem, if it happens.
