Organizing RPC via QT: Library for Communication between Objects in Different Processes One of the key features of the QT framework is providing communication between objects via signals and slots. For QT developers, this is a very convenient and organic way to do things, but the nature of the feature does not allow to communicate between ... PySide/PyQt Tutorial: Creating Your Own Signals and Slots ... It would be possible to have the slots to which the resized and moved signals are connected check the new position or size of the circle and respond accordingly, but it's more convenient and requires less knowledge of circles by the slot functions if the signal that is sent can include that information. PySide; PyQt Inter-Process Communication | C++ GUI Programming with Qt4 ... Inter-Process Communication. The QProcess class allows us to run external programs and to interact with them. The class works asynchronously, doing its work in the background so that the user interface remains responsive. QProcess emits signals to notify us when the external process has data or has finished. Qt 4.8: Inter-Process Communication in Qt QCopChannel is only available in Qt for Embedded Linux. Like the QtDBus module, QCOP extends Qt's Signals and Slots mechanism to the IPC level, allowing a signal emitted by one process to be connected to a slot in another process, but unlike QtDBus, QCOP does not depend on a third party library.

A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but a client programmer may always subclass widgets to add other signals to them. A slot is a function that is called in response to a particular signal. Qt/C++ - Lesson 024. Signals and Slot in Qt5 - EVILEG
