[Qt-interest] bloody ungraspable control of my pusbutton

[S. Aguinaga]

Dear Fellows,

I have a question for the best of you.

I have a button that initiates a tone stimulus using my audio device.
This stimulus is meant to be continuous until the pushbutton is toggled,
but what is happening is that once my code goes into the audio loop it 
never allows control back to my pushbutton, in other words, I can't toggle it
and right now the only way out is to go to the terminal and do control-C.

here is the loop:

while ( contToneButton->isChecked() ) {
        chk_msg();
        c = (int) floor((1 + oct0) * ncue / 2);
        cue(c);
        (void) ar_io_cur_seg(dvid);
};

have any of you come across something like this an do you mind sharing 
your methods?


Thank you
