[Eric] Eric4 and interactive PyQwt Plots

[Darryl Wallace]

Basically, when using the startup environment script I previously 
mentioned, or using ipython, you can create a window from the 
command-line and the event-loop returns to the commandline and you can 
still access the Qt Object.

So when, for a PyQwt plot, I call plot.show(), the plot is displayed and 
I can continue to modify the contents of that plot (like change titles, 
make the window bigger, etc.) from the command line. 

Currently in eric, if I run a script where the end result is displaying 
a plot I can't continue to work from the shell window's command-line 
until I close the plot window.  I would still like to be able to access 
the active plot objects from the shell's commandline, as well as do 
other things.

So, using PyQwt (http://pyqwt.sourceforge.net/cli-examples.html)* *I can 
generate a plot.  Do some stuff.. add a new line to that existing plot 
from the command-line after it's already been displayed.  Just some more 
flexibility.

I hope this helps clear things up.  Is this possible?
