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. Qt Namespace | Qt Core 5.12.3

Hi, edit: dont bother, solved my project consists of two parts: One GUI-project and one library that exposes an API consumed by the GUI app. Both of them are qtcreator projects. Everything works fine without signals and slots.

Qt and C++11 | ICS - Integrated Computer Solutions With most C++ compilers now providing good support for the latest language standard, C++11, let's look at some of the new language features that are particularly useful for use in Qt programs. Qt - Passing objects among threads Communication between threads in a qt program is essentially done by using signals/slots. This is by far one of the most easiest and stable mode of communication amongst threads of a program.
When the signal/slot is actually executed it is done in the receiver object's thread. Qt::AutoConnection (the default parameter) is a bit smarter. When a signal is emitted Qt checks the connection type, if it's an auto connection it checks the sender and receiver's thread affinity (the threads they live in). user interface - Qt signaling across threads, one is GUI Jan 24, 2010 · Qt signaling across threads, one is GUI thread? I read about Qt handles signal slot connection type based on where the object live. – Passionate programmer Jan 19 '10 at 4:03. Updated response, I may have over simplified a bit, but in most cases it will handle the work.
