Signaling Another Process (The GNU C Library) The return value from kill is zero if the signal can be sent successfully. Otherwise, no signal is sent, and a value of -1 is returned. If pid specifies sending a signal to several processes, kill succeeds if it can send the signal to at least one of them. There’s no way you can tell which of the processes got the signal or whether all of ... Organizing RPC via QT: Library for Communication between ... 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 ... multi-tier architecture: how to have out-of-process signal-slot? For sure it is an important part of a multi tier distributed application, but I would like to focus on an easy way for exchanging signals and slots between processes. I continued googling to find something and I found something. I found something that was available in the early days of Qt (at least before Qt 5): QtopiaIpcAdaptor.

c++ : Qt Can't Have Model and View on different Threads? I wanted to cite this mailing list question from me about models and views on different threads in Qt (along with the ensuing answers). The qt-interest mailing list entries from 2009 seem to have all but disappeared from the web, but I found this one in an Internet Archive cache off of "gmane". Using Qt for non-graphical applications - eLinux Signal/slot mechanism I The signal/slot mechanism is a core mechanism of the Qt framework I Objects can de ne slots, which are functions called in response to a signal being received I Objects can emit signals, which are events optionally associated with data I A signal of a given object can be connected to one or more Qt: Signals & Slots - PUC-Rio
Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood. In this blog article, I show portions of Qt5 code, sometimes edited for formatting and brevity.

QProcess Class Chapter 1: Your first PyQt programs - thehackeruniversity.com Qt uses a signal and slot mechanism to handle input events. In our case, a signal is emitted when the user clicks on the button we’ve created. A slot is code that processes this signal. A slot can point to a Python function or another slot. The emitted signal is connected to the infinite loop which processes user events.
