Qt pas de tel slot qthread

Hi all, I use QUdpSocket from Qt5.6.2 on Ubuntu 16.04 to get 4 channels audio stream from a specific device, sending Udp datagrams. Everything works fine until it reaches the 11402th audio datagram of the 4th channel, every time, at each test.

The recommended way of working with threads in Qt has changed since the documentation was written. It is usually better not to add signals, let alone slots, to QThread. Instead, create a QObject (derived) instance, and call moveToThread on it to move it to the thread. Put your signals and slots in this worker object instead. It is important to remember that a QThread instance lives in the old thread that instantiated it, not in the new thread that calls run(). This means that all of QThread's queued slots and invoked methods will execute in the old thread. Thus, a developer who wishes to invoke slots in the new thread must use the worker-object approach; new slots See full list on doc.qt.io De plus ton slot downloadFinished étant dans la classe dérivée QThread il n'est pas exécuté par le thread contrôlé par ce QThread, mais par le thread appelant (le thread principal), donc tu perds tout l'avantage de l'utilisation du thread, seuls les slots des QObjets ayant une affinité avec le thread sont exécutés par le thread (ceux That's a "direct" slot connection and in this case slot() will be executed in caller thread, one that raised a signal. So in order to communicate with another thread, Qt allows another kind of signals, queued connections. Instead of calling a slot(), caller leaves a message to object that owns this slot. See full list on blog.debao.me Priority QThread:: priority const. Returns the priority for a running thread. If the thread is not running, this function returns InheritPriority. This function was introduced in Qt 4.1. See also Priority, setPriority(), and start(). [slot] void QThread:: quit Tells the thread's event loop to exit with return code 0 (success).

I am using QT framework. I have been using SIGNAL-SLOT for a while. I like it. :-) But I cannot make it work when I use QThread. I always create new thread using “moveToThread(QThread …

How Qt Signals and Slots Work - Part 3 - Queued and Inter Thread Connections This blog is part of a series of blogs explaining the internals of signals and slots. Part 1 - How Qt Signals and Slots Work Jun 17, 2010 · It wasn't until Qt 4.4 that QThread::run() gained a default implementation. Previously, the only way to use QThread was to subclass. With the addition of thread affinity and support for signal and slot connections between objects of different affinity, suddenly we have a convenient way of working with threads. Qt comes with several additional examples for QThread and QtConcurrent. Several good books describe how to work with Qt threads. The most extensive coverage can be found in Advanced Qt Programming by Mark Summerfield, Prentice Hall - roughly 70 of 500 pages cover QThread and QtConcurrent. If you want to have those slots called in the thread running the client connection, you have to move the object into that thread. Which means in your case the best option is to not derive from QThread at all but create your client handler as a QObject subclass and simply "move" it to a new QThread instances, see QObject::moveToThread() Traditional syntax: SIGNAL and SLOT() QtCore.SIGNAL() and QtCore.SLOT() macros allow Python to interface with Qt signal and slot delivery mechanisms. This is the old way of using signals and slots. The example below uses the well known clicked signal from a QPushButton. The connect method has a non python-friendly syntax.
