ListBox horizontal scrollbar does not go away

[ytub...@gmail.com]

Hi,

I'm on a Linux XFCE machine with wxPython 3.0.2.0 installed.

I have an wx.ListBox widget with some items. When i add a new item that is long
the horizontal scrollbar appears, if i remove the item the horizontal scrollbar is still there.
To reproduce:

1. run test.py
2. click "button" to add the long item (the horizontal scrollbar should appear)
   
3. click "button" again to remove it (the horizontal scrollbar is still there)

Is there a way to remove the scrollbar?

NOTES

- On Windows 7 the scrollbar does not appear so the problem does not exist.

- Changing theme does not make a difference.

- I search the group/google and i only managed to find those two issues, that might have something to do with my problem:

Could this issue be because of the interaction between GTK and XFCE?  It appears to work with KDE ( again that is the interaction between GTK  and KDE).  Have you tried other managers? Other distro's?

I see it on GNOME 3 also so it's not just XFCE.

I guess the only thing to do is to refresh the layout in the code that removes the expanded text (node).  I don't have anything very small that I can play with but I can say it works for me on KDE (I'm using openSUSE leap).  Maybe you can post something small we can take a look at to determine the real cause.

I have tried with Refresh() & Update() but no changes, the scrollbar is still there.

There is already the test.py
