However, it relied on the Qt Moc pre-compiler tool, which meant any project that wanted to use this feature had to use follow along with the Qt idiom, which really made Qt applications look potentially foreign despite being written in C++. Synchronizing Threads | Qt 5.12 Qt provides low-level primitives as well as high-level mechanisms for synchronizing threads. Low-Level Synchronization Primitives. QMutex is the basic class for enforcing mutual exclusion. A thread locks a mutex in order to gain access to a shared resource.
Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code. The concept is that GUI widgets can send signals containing event information which can be received by other widgets...

function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes. Since signals and slots are type-safe, type errors are reported as warnings and do not cause crashes to occur. For example, if a Quit button's

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. Qt signals and slots for newbies - Qt Wiki function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes. Since signals and slots are type-safe, type errors are reported as warnings and do not cause crashes to occur. For example, if a Quit button's c++ - Qt Signals and slot thread safety - Stack Overflow Let's say I have a signal change connected to a slot notify. If the change signal is emitted, the notify slot will start executing. Now what happens if a second change signal is emitted and the first notify slot didn't finish its execution? Is the second slot launched concurrently with the first? And if so, is Qt handling the thread-safety or ... Threads and QObjects | Qt 4.8 Signals and Slots Across Threads. Qt supports these signal-slot connection types: Auto Connection (default) If the signal is emitted in the thread which the receiving object has affinity then the behavior is the same as the Direct Connection. Otherwise, the behavior is the same as the Queued Connection."
