Oh!that might be the case. I will have a check

Thank you. Problem solved. slow tasks block the event loop. I move them to worker threads.

I understand now. The program can not response since it's in sleep. But What I want to implement is, a process write to a pipe, another process read the data from the pipe and update the progressbar. A block read is the same as sleep, it would hang the process. However, a non-block read is too wasty. Any suggestion?

Just very basic code sample like

progressBar->setMaximun(max);
for ( int i=0; i<max; ++i="" )
{
="" progressbar-="">setValue(i);
sleep(1);
}
