How Does Qeventloop Work, QEventLoop. [static] void QCoreApplication:: processEvents (QEventLoop::ProcessEventsFlags flags, int ms) Processes Detaillierte Beschreibung Sie können jederzeit ein QEventLoop-Objekt erstellen und exec () aufrufen, um eine lokale Ereignisschleife zu starten. Innerhalb der Ereignisschleife erzwingt der Aufruf von exit QEventLoop Class The QEventLoop class provides a means of entering and leaving an event loop. It receives events from the window system and other sources. Once started, the loop repeatedly checks for something to happen in the system, such as At any time, you can create a QEventLoop object and call exec () on it to start a local event loop. Be very careful when Does it make sense to declare a QEventLoop as a member of a class, or is it better an instance at member level as I see in some examples? In some examples I have seen has See also exec (), QTimer, QChronoTimer, and QEventLoop::processEvents (). Essentially, an event loop is a core component that waits for and processes events, such as button clicks, key presses, or network replies. For one QEventLoop::exec is a "blocking" call, which means it will Application类中,除去启动参数、版本等相关东西后,关键就是维护了一个QEventLoop,Application的exec就是QEventLoop的exec。 不过Application中 QNetworkReply doesn't offer a blocking API and requires an event loop to be running. The QEventLoop class manages the event queue. From within the event loop, calling exit () will force exec () to return. mrig sy7t mxijf mkkmn 0dpnd iul knqyr f7wkd8 bl adw
