dynamic timer firing different jobs

SherifOmran

I am trying to create a dynamic timer that fires different jobs
my implementation is as follows. But in the fired job function i get always the fired job =2 ! I need someway to say take the current value of the counter and don't change it.

            for (int counter =0; counter <2; counter++) {
            timers[counter].singleShot(seconds*1000, [&](){
                FireJob(counter);
            }


void FireJob(int jobcmd)
{
qDebug() <<  jobcmd;
}

any idea?

Hi
Hmm yes you are capturing the counter by reference ( like a pointer) so its
always the current (loop) value
Try with [=] to capture it as a copy.

@mrjj thank you for your reply. Can you please show me how to use the code by copy, this is new to me.

Hi
its just = instead of & in the []

for (int counter =0; counter <2; counter++) {
            timers[counter].singleShot(seconds*1000, [ = ](){
                FireJob(counter);
            }
