As soon as I uncomment the thread lines the program stops working. I've tried to move the launch of the new thread and also the "connect" but nothing is working. I think I'm not understanding well how Qthread works even after reading thedocumentationand looking at the examples on...

In this specific case, a more efficient construct would beQAtomicInt. This gains atomicity from its use of special CPU instructions. This is a low level class that could be used to implement other threading constructs. Edit - Complete Example Using threads with shared state correctly is not tr...

When we use the print() function to output a number, the number is sent to the output buffer along with a newline character (\n). Since we are working with an interactive environment, such as a terminal, the print() function operates in a line-buffered mode, which means that the ...
We useList_Leftto only pass the same number as argument as the slot, which allows connecting a signal with many arguments to a slot with less arguments. QObject::connectImplis the private internal function that will perform the connection. It is similar to the original syntax, the difference...
The event will be deleted right after being processed in the thread that processes it. An event posted using a QueuedConnection is a QMetaCallEvent. When processed, that event will call the slot the same way we call them for direct connections. All the information (slot to call, parameter...

and make it a bit better by adding vulkan files listed above to \qtbase\src\gui\vulkan (if you have version lesser than 5.11.2), and by removing “try { } catch (…) {}” surrounding the user code in qtbase\src\corelib\thread\qthread_unix.cpp or build with -DQT_NO_EXCEPTIONS. ...
