[Visualpython-users] help to activate programmatically the scene of VPython 3.2.9

[Andrey A. <an...@uc...>]

Dear Friends,

I use VPython 3.2.9 for Windows (XP).
I have an application with one (or several) VPython scenes full of objects
and another Tkinter window with widgets.
When I click on the Tkinter Button my VPython scene window is not active, 
then the user have to click on VPython scene in order to activate it.
This is not a big trouble, but I need to accelerate my application.
So could anyone help me to solve this problem:
        Within my application how can I make the VPython scene to be the 
current active window after clicking on the widget button?

I don't know whether it is simple to do in next VPython 4.
ThX

Andrio
