Several experiments have been implemented on a dSPACE platform with a laboratory permanent qt synchronous slot magnet synchronous machine (PMSM), and the experimental results microgaming poker network login validate that the improved rotor position estimator based on the continuous signal of third harmonic flux-linkage can achieve accurate Qt: (Nearly) synchronous QNetworkAccessManager calls This way my user-defined slot for the pnam->finished() signal was called immediately, and I could be sure to have the HTTP reply at the end of this code snippet.. Found here: Qt-Interest Mailing List: QNetworkAccessManager and QNetworkReply, synchronous Qt: wait for a signal in synchronously mode Qt libraries work using the mechanism called signal-slot. Basically this is a optimal way to make an asynchronous communication between objects in any kind of conditions and transmitting any kind of data. However, sometimes, may happen the need to wait for a very short time event (for example wait for the end of a short animation). Qt Tutorials For Beginners 5 - Qt Signal and slots - YouTube Apr 13, 2016 · Understanding Signals and Slot in Qt is not very difficult.

Problem with QT / Threads / Signals / Slots - C / C++ The Signals and Slots mechanism can be used in separate threads, as long as the rules for QObject based classes are followed. The Signals and Slots mechanism is synchronous: when a signal is emitted, all slots are called immediately. The slots are executed in the thread context that emitted the signal. ***SNIP New-style Signal and Slot Support — PyQt 4.11.4 Reference Guide New-style Signal and Slot Support¶. This section describes the new style of connecting signals and slots introduced in PyQt4 v4.5. One of the key features of Qt is its use of signals and slots to communicate between objects.

Qt has its own event loop, and its own Observer implementation (signals and slots).
Hello, I am communicating with a device in Qt using a QIODevice (specifically a QSerialPort). Normally it is easy to use the asynchronous signals/slots mechanism of QIODevice to process replies from the device and perform actions. However, the particula... How to Use Signals and Slots - Qt Wiki

Support for Signals and Slots — PyQt 5.11 Reference Guide Support for Signals and Slots¶ One of the key features of Qt is its use of signals and slots to communicate between objects. Their use encourages the development of reusable components. A signal is emitted when something of potential interest happens. A slot is a Python callable. How Qt Signals and Slots Work - Woboq
