QUESTION

here is my LiveCamera subclass from QQuickPaintedItem
...ANSWER
Answered 2022-Apr-17 at 16:34According to the screenshot, this isn't a crash. The program seems to be to busy (on the main/gui thread) to respond to user interaction, resulting in Windows saying the application is not responsive.
To debug such a problem, you should use a debugger, pause the program and see what he is doing (on the main thread).
The problem in this case is that you are running CamThread::run
(which executes an infinite loop) inside the main thread, instead of running it on a separate thread as intended. You shouldn't call QThread::run
explicitly, but call QThread::start
, which will start a new thread and execute the QThread::run
function on that new thread.
Note that QThread::quit
does nothing in your case, as by reimplementing QThread::run
, the QEventLoop
isn't started on that thread. Either you should start the event loop or you should implement your own signal, to interrupt the infinite loop inside CamThread::run
to let the thread finish gracefull.
