[Paraview] Getting user input while in python shell plugin

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

Hi,

Thank you both Pat and Utkarsh.

QApplication.activeWindow() appears to just work fine at finding the
main window.  As a fall back looping through
QApplication.topLevelWidgets() and doing a check like this:

   isinstance(wid, PyQt4.QtGui.QMainWindow) and re.search('kitware paraview', wid.windowTitle(), re.IGNORECASE)

works OK too (obviously I'm making an assumption about the title).

Thanks again

Matt Wilkins
