which GUI package are you using?

you responde with:
It's the question, the image only captue from other software, widget not implement currently.

But in previous post you respond to Deanhystad:
Yes, I already do that use two 'Scale' widget.

If that's the case, you must be using some graphics package, Which one??
for instance tkinter, Qt5, Kivy, wxpython or something else.
