sleeping whilst GUI runs
Message 1 in thread
Hi everyone
I have a problem where I need to allow a device I'm monitoring to wait
for 5 seconds before taking more data. The monitoring function is part
of a QWidget class called k_master. I have another class which displays
other information about the device (which is provided by the k_master
class). Is there a way I can make the function wait whilst the rest of
the code carries on running. Do I need to use threads for this?

Ross,
You could use QTimer, and while processing data call
QApplication::processEvents() from time to time. This will make GUI
responsive
if processing takes too long.
