Wait for execution

gRicky

Hi All,

I have a for loop in my GUI thread which sets some command but from one command to the next my loop should have to wait the answer from a serial device before going on. What is the right method to pause the for execution while the code is answering and receiving from the serial device?

My pseudo code is:

@ for i=0 to 1000
set message_1
set message_2

                    send command to the serial device
                    wait for answer

                    update tablewidget
               go to next@

Please reformat this pseudocode and wrap it in '@' tags.

It's generally considered better to use the event loop together with signals and slots, rather that waiting explicitly. But, if you insist, this piece of code should do the work:
@
forever {
if (isAnswer == true)
break;
else
qApp->processEvents();
}
@
