How do I set the QThread priority to InherentPriority when it's running?

CJha

Hi, I know I can start a QThread myThread with QThread::InherentPriority by using myThread->start(). When the thread is running the function QThread::setPriority(QThread::Priority) can be used to change it's priority, but the documentation says

The priority argument can be any value in the QThread::Priority enum except for InheritPriority.

So, if I start my thread such as myThread->start(QThread::HighPriority) then how can I want to switch back to QThread::InherentPriority? Will I have to quit and restart again, is that the only option?

@CJha
Did you try QThread::setPriority(QThread::Priority priority) while the thread is running?

Also, what platform are you on?

@JonB I tried it, it says

QThread::setPriority: Argument cannot be InheritPriority

For any other priority, it works fine (at least no error or warning).
I am using Windows 11.

@CJha
You said so far it was QThread::InherentPriority, but transpires you meant InheritPriority.

Then I can only guess you must fetch/determine the caller's priority and use that to pass the relevant actual value to setPriority().

@JonB It is InheritPriority It was a mistake from my side. Yes, I think you are right, I will have to go to the caller for that. Thanks!
