I'm not sure what you are trying to do here - but it seems to me that
you are not properly designing your application. You really shouldn't
use the Designers code-insertion features. The reason is simple: you
the have two tools to write code in instead of one (your editor/IDE).
And you don't make plotkey* global - use instance variables.

 So I'm going to describe how I dow work with PyQt:

- I create a Widget in the designer
- compile it using pyuic
- _extend_ it
- write my code in the extended version

So I end up with something like this (I use modules to separate


where views/ looks like this:

class Plot(ui.plot.Plot):
    def __init__(self, *args):
         ui.plot.Plot.__init__(self, *args)
         self.plotkey1 = <whatever>

    def update(self):
         # access self.plotkey here
