[Qt-interest] Waking-up a sleeping thread

[Scott Aron Bloom]

Don't use sleep.. 

One suggestion, that has worked for me.. rather than calling sleep..
only start the thread when you have info to process.. otherwise exit
out.

Subject: [Qt-interest] Waking-up a sleeping thread

Is it possible to "wake-up" a thread, after calling sleep(secs) on it?
I have a thread that periodically does a job. I have the following
pseudocode in the run() function of my thread:
...
while (!stopped) {
	sleep( jobInterval);
	if (stopped) break;
	doLengthyTask();
}
...
my thread deconstructor is
myThread::~myThread() {
    stopped = true;
    wait();
}

My problem is when the user tries to exit the app, the program will
stall for up to jobInterval seconds, as the thread might be sleeping,
and the deconstructor waits for it.
Is there another way to handle this?

Thanks,
Harry
