[vtkusers] Get active renderwindow

[KS Jothybasu]

Here is it:

self.win1=QVTKWidget()
self.win2=QVTKWidget()
self.win3=QVTKWidget3()
self.win4=QVTKWidget()

Tiled in a mainwindow

Now when I want to measure distance using distance widget, how to pass the
active renderwindowInteractor  to the distacne widget.

if we know the active render window, we can use renwin.getInteractor() and
pass it to it.

Otherwise, I have to create separate functions to each and every window I
would like to measure.

I am trying from PyQt side, is there any method to get active widget..there
should be isn't it??

Thanks

Jothy
