What is the difference between QThread::terminated() and QThread::finished()?
-
I am writing an application that gets frames from a camera. I need to release the camera resources. Should I do this in QThread::terminated() or QThread::finished()?
I would like to do it when the thread has completely finished executing all the code it had to execute.

Check the documentation: "QThread::terminate()":http://qt-project.org/doc/qt-5.0/qtcore/qthread.html#terminate is a slot that terminates the execution of the thread and "QThread::finished()":http://qt-project.org/doc/qt-5.0/qtcore/qthread.html#finished is a signal that is emitted by the thread before it finishes executing.

terminated is emitted when the thread has been, well, terminated (forcibly stopped) which also means that it's state is not guaranteed to be clean.

Please note that since Qt 5 the signal QThread::terminated() has been removed, because its emission cannot be guaranteed.
