[Discuss-gnuradio] Signal Generator GUI

[cfk]

Gentlemen:

 I've got me USB2.0 card and I can generate 900khz sine (or perhaps cosine) 
waves with the usrp using usrp_siggen.py, so far so good.

 The next step is I'm trying to build a point and click gui to control the 
usrp as a modest signal generator. So, I have put together the attached 
python script, which does run.

 At this point, the program starts up and the sliders and buttons are active, 
although they dont do what I need them to do yet.

 When the window is closed by clicking on the X in the upper right corner, 
then sg.start starts the 900khz sine wave and the next Enter, stops the usrp, 
so I know that sg.start() and sg.stop() do connect all the way to the usrp.

 The problem I am having is that when I call sg.start() by clicking the 
"Start" button, python tells me that:

 'module' object has no attibute 'sg'

The issue seems to be that 'sg' is not known inside the appropriate routine. 
So, I think I am very close, but my naivety with python is getting in the way 
a little bit.

 I wonder if someone else would look at this and see where I am going awry. 
I'll be here spending the day working through this problem and reading the 
new python book just received from Amazon.com while the Southern California 
skies are a bit rainy.
