[Paraview] Getting user input while in python shell plugin

[m.c.wilkins at massey.ac.nz]

Hi,

I am writing a plugin in the python shell.  I can get source info with
ActiveSource, or FindSource, but I need to be able to get some info
from the user.  Is there a way to popup a dialog box?  I know I could
just import Qt myself and do it, but I am guessing paraview already has
an active Qt mainloop somewhere, and starting another wouldn't be
smart.

Any help would be much appreciated please 

Thank you
