qobject::connect: no such slot - NeilCowles1's blog I'm writing a program using Qt 4.4.3 and I'm using connect in two different places, and in both places it says no such slot. QObject::connect: No such slot - Qt Programming - qobject::connect: no such slot The Independent Qt Tutorial - Chapter 6 - Digital Fanatics | News. Signals & Slots | Qt 4.8 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.

Today I want to share 13 mistakes regarding signals, slots and connect statements and how to find them at compile time with clazy, our open-source static-analyzer for Qt. Clazy is a compiler plugin which generates warnings related to Qt.

There are several ways to connect a signal in Qt 5. Old syntax. Qt 5 continues to support the old string-based syntax for connecting signals and slots defined in a QObject or any class that inherits from QObject (including QWidget) connect( sender, SIGNAL( valueChanged( QString, QString ) ), receiver, SLOT( updateValue( QString ) ) ); Signals and Slots in Qt5 - Woboq As you might have seen in the previous example, the slot was just declared as public and not as slot. Qt will indeed call directly the function pointer of the slot, and will not need moc introspection anymore. (It still needs it for the signal) But what we can also do is connecting to any function or functor: New-style Signal and Slot Support — PyQt 4.12.3 Reference Guide

(Michael Sinz) c++ - QObject::connect: No such slot on QT - Stack Overflow From signals and slots doc: The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.) c++ - QObject connection function - Stack Overflow One thing to note; since you're using Qt 5, there's a new signal slot connection syntax, which will allow you to specify any function and not just those defined as slots.
