[PyQt] callback problem

[Oguz Yarimtepe]

Hi all,

I am trying to use callbacks at my  gui: http://rafb.net/p/2YKz3Z77.html

I am trying to detect the unpluging of video cable by using xrandr and
callbacks. But i need to run the callbacks during the gui runtime. It
runs only one time when the main function is called. What should i do
to make it run as a background process and keep checking the xrandr
output.
