Stuck on trying to update painting of an Attitude Indicator dial

[George V. <geo...@gm...>]

I have been stuck for a week trying to finish an implimentation of an
Attitude Indicator in PyQwt. It is derived from the original dial demo and
the intent was to seperate it out, improve the graphics, and make a class
that can be loaded into a frame from Designer. I don't know enough to make
it an actual widget. It all works fine on the program initialization. After
that I want to move the sliders (eventually IMU accellerometers) and
update/repaint the screen. Using setValue on the dial will move the needle
graphics but I can't find a way into the code to coordinate the sky
graphics with it. 1) I've looked at update() but that seems to be related
to Widgets and has no effect.
2) Tried to call into the "drawNeedle", "drawContents" routines directly
but that seems convoluted since the arguments to be passed are allready
determined. This approach ultimately results in "Painter not Active"
errors. Also looked at paintEvents which I suspect may be the right
approach but have not been able to get it to work either. I'm sure I'm
missing some fundemental technique and I would appreciate any help with it.
Thanks,
