Thanks again - all is good now :-)
I have one further question, is there an elegant way to load a widget from
a UI file which you can then inherit from ?
as in:
class NewUI(uiwidget_base, uiwidget_form):
def __init__(self):
super(NewUI, self).__init__(parent)
self.setupUi(self)
etc.
this is what I came up with, just tested with maya2015, maya2016..

(I do know there is QtCompat.load_ui() but I needed this functionality as
well)
