Hi
I have a function that I need to execute as in a thread in response to
some event. The event is not a signal.
My function do_something() typically takes less than 20 milliseconds to
finish.
Method-1
----------
1. I derive from QThread and override run() to:
void run()
{
do_something();
//copy results
}
I will create my thread object during initialisation and when the time
comes,
I will just call thread->start().
Method-2
-----------
2. I derive from QThread and override the run() function to do something
like this:
void run()
{
my_mutex.lock();
wait_condition.wait(&my_mutex);
my_mutex.unlock();
do_something();
//copy results
}
During initialisation, I create the thread object and call
thread->start() and it waits for the QWaitCondition.
When needed, I call wait_condition->wakeAll().
Which solution is better?
Method-1 is simpler for my use case as I find QWaitCondition too clumsy
to use. But I am worried about possible
overheads of starting the thread new every time.
Please remember that I don't need signals and slots for this.
Any help is highly appreciated.
Thanks and regards,
Syam
