[Qt-interest] Basic QThread question

[Phil]

Thank you for reading this.

This is the basic situation.

My main class polls a hardware device every second which returns an int 
value. The hardware device is slow and so the GUI is blocked for about half a 
second each second.

To overcome the blocking, the hardware class is now sub-classed from 
QThread and has a function similar to the following as well as a run() 
function:

int hardware::getValue()
{
    return x;
}

I can see that the run() function starts each second and then stops as it 
should.

My question is, how do I have run() return the value x? Should I periodically 
call run() from the main class (hardware.run()) which in turn calls getValue() 
which in turn emits a signal to return x to the main class via the signal/slot 
mechanism?

It seems a bit convoluted, perhaps there is a more practical method?
