QObject with QTimer moved to QThread - QTimer::timeout() not processed until wait()

[amleto]

use signals and slots. not while(true) or equivalent

[airproject]

My doWork() is processing some number of items. It should process this data unless user presses Pause button or Stop button. I initially made a QThread subclass which in run() had while(true) (i guess that this is not a bad practice in thread?) and some exit conditions checking flags set by signals from GUI. As "this->moveToThread(this)" trick is not a good thing to do i have rebuild my QThread subclass to QObject subclass.
How would you rebuild the while(true){} processing loop to fit "QObject moved to QThread" approach?
Best regards.

How do you expect me to say how you can refactor your while loop when you have given no information about what it actually does and where the input comes from

I give up. Just use this.
http://doc.qt.io/qt-4.8/qcoreapplication.html#processEvents

[airproject]

If you suggest to use:

doWork()
{
(...)
while(true)
{
QCoreApplication::processEvents();
(...)
 
}

doWork()
{
(...)
while(true)
{
QCoreApplication::processEvents();
(...)

}

it does not solve the problem.

read my sig


All your timer does is send signal. you can put your timer anywhere. Why does it have to be in heavy processing thread?

[airproject]

I can redesign and put a timer outside the processing thread. Still for my own knowledge i would like to know it there is a way of installing the QTimer inside a Thread.

Sorry for not pasting the original code. It is not my property and i cannot share it. As it is quite big i just tried to extract the highlights.

You can put a timer anywhere you want, including in threads. But if you block the event loop of that thread then signals wont fly out and slots inside wont be executed. It's pretty straight forward.

[airproject]

I agree with you. I do not know how to make these timer events propagate in my while() loop. According to docs: QCoreApplication:rocessEvents()
"Processes all pending events for the calling thread according to the specified flags until there are no more events to process."

So putting it inside a while() loop should do the job - sadly it does not, ..or i am doing something wrong.
Thank you anyway.

[amleto]

you could be doing any number of wrong things so I'm not going to speculate any further without code.
