Hi all,

I’m trying to create a GUI for my GNURadio program using python-gtk on a  
USRP E100. I have GNURadio and pythong-gtk working separately. But now  
that  
I’m combining them, the graphic windows goes blank and waits for the  
GNURadio part to finish. Is there a better way to do this?

Thank you,  
Rithirong Thandee

Fon -

Can you detail how you are combining them? If you are executing GNU  
Radio  
stuff from the primary thread in your GUI application, it will stop  
re-drawing the window (because the thread is busy executing GNU Radio).

Also, all GUI updates must happen from your main thread.

Cheers,  
Ben
