Use this macro to replace the slots keyword in class declarations, when you want to use Qt Signals and Slots with a 3rd party signal/slot mechanism. The macro is normally used when no_keywords is specified with the CONFIG variable in the .pro file, but it can be used even when no_keywords is not specified.
Vývoj popularity programovacích jazyků na GitHubu Ja tam zase hovorím, že ak používam v Qt signály a sloty tak sa nemusím o ne vôbec starať. Stačí ak zruším jednu stranu spojenia a o zvyšok sa postará QObject sám (každý objekt ktorý sa používa vo volaní connect musí byť potomkom QObject-u … Programovací jazyk C++ - PDF Programovací jazyk C Aleš Čepek 155GIT3 February 20, 2014 Aleš Čepek (155GIT3) Programovací jazyk C++ February 20, / 192 Copyright c 2007, 2008, 2009, 2010, 2011,2012 Aleš Čepek Permission Měřič Variability Tepové Frekvence - PDF
Qt; QTBUG-74153; problem on passing pointer to pointer of array to slot and signal
A Deeper Look at Signals and Slots - elpauer
Signals and Slots are a convenient way for QObjects to communicate with one another and are more similar to callback functions. In most circumstances, when a "signal" is emitted, any slot function connected to it is called directly. The exception is when signals and slots cross thread boundaries.
Signals and slots are primarily used for events handling, but you can use it for easy communication between objects too. When two windows need to communicate with each other, you can use signals and slots. Communication this way is much easier than doing it with pointers. c++ - Pointer to a Qt Slot - Stack Overflow Slots and signals are identified by their names (when you do use SLOT(set_pwm(unsigned long)) in your code, you are constructing a string). You can simply store the name and the object and then call the slot using QMetaObject.. You can use pointers to member functions in C++ (see the C++ faq), but in this case I'd suggest to use Qt's meta object system. Signals & Slots — Qt for Python
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 ) ) );
Best practice for passing pointers as sender for async signals Best practice for passing pointers as sender for async signals. This topic has been deleted. I retain the smart pointer in ProjectLoader's signal slot. @ void MainController::didLoadProjects(QSharedPointer
