Thank you, this is what I needed, good stuff.  The only thing I
couldn't immediately figure out from that post, was what to do with
widgets that need a parent, because I couldn't get hold of the main
paraview window widget.  Anyway this is what I did:

---
import PyQt4.QtGui

# this is a dummy widget to use as the parent for other widgets that need a
parent
wid = PyQt4.QtGui.QWidget()

# get some user input
ret = PyQt4.QtGui.QInputDialog.getText(wid, 'hi', 'first question')

# do some other stuff

# oh dear a warning
ret = PyQt4.QtGui.QMessageBox.warning(wid, 'hi', 'there was a recoverable problem', PyQt4.QtGui.QMessageBox.Ok, PyQt4.QtGui.QMessageBox.NoButton, PyQt4.QtGui.QMessageBox.NoButton) 

# maybe get some more input
ret = PyQt4.QtGui.QInputDialog.getText(wid, 'hi', 'second question')
---


Thanks

Matt
