Qt signal slot infinite loop

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. Worker thread stops processing events during infinite loop I've created a Worker object in Qt to process video input indefinitely, and then move it into a QThread to keep the UI thread going. The problem is, I designed it such that the video capture function runs in an infinite loop until interrupted by a flag, and the flag was supposed to be set by a slot in the Worker object, but since the Worker object is inside the infinite loop, it never Signals & Slots — Qt for Python An overview of Qt’s signals and slots inter-object communication mechanism. Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks.

Signals and Slots - PyQt Programming - pythonstudio.us These signals can be connected to any callable, that is, to any function or method, including Qt slots; they can also be connected using the SLOT() syntax, with a slotSignature. PyQt checks to see whether the signal is a Qt signal, and if it is not it assumes it is a Python signal.

The QObject QObject is the base class of almost all Qt classes and all widgets It contains many of the mechanisms that make up Qt events signals and slots properties

Особенности Qt: слоты и сигналы, описание QObject и QApplication, виды окон и т.д.Это базовый класс для всех объектов Qt. Его наследует любой класс использующий сигналыОн в свою очередь генерируется, если в коде обработки события имеется вызов(макрос) emit signal().

Сигналы и слоты в Qt: установка, особенности работы,… Qt сигналы и слоты помогают включить ориентированную на событие функцию в графические пользовательские интерфейсы приложений.Так как многие классы инфраструктуры предоставляют к ним различный доступ к предопределенным Qt сигналам и слотам. Qt 4.1: Signals and Slots Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the featuresThis prevents infinite looping in the case of cyclic connections (e.g., if b.valueChanged() were connected to a.setValue()).
