Another high-level form of communication is provided in Qt's signals and slots mechanism. Threading Basics | Qt 5.12 If two threads have a pointer to the same object, it is possible that both threads will access that object at the same time and this can potentially destroy the object's integrity. Networking and Connectivity | Qt 5.12.2 Qt Network can also handle lower level protocols like TCP and UDP. Classes like QTcpSocket and QUdpSocket enable the developer to send and receive messages using the TCP or UDP protocol.Name resolution is done with QHostInfo.

Hi People, I have a problem with Qt meta-type system and the signal and slot connections. I try to connect a signal and slot with each other. The signal looks like this: @ signals: void sigSaveFileName(QString&); @ and the slot: @ private slots: void slot... PyQt/Threading,_Signals_and_Slots - Python Wiki The worker thread is implemented as a PyQt thread rather than a Python thread since we want to take advantage of the signals and slots mechanism to communicate with the main application. class Worker(QThread): def __init__(self, parent = None): QThread.__init__(self, parent) self.exiting = False self.size = QSize(0, 0) self.stars = 0 Qt5 Tutorial Signals and Slots - 2018 - bogotobogo.com 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. QThread Class | Qt Core 5.12.3
