Has wxpython SpinCtrl/SpinButton changed between C

问题:

I have started to look at converting one of my projects from python2.7/wxpython 3.0.2.0 to python3.5.2/wxpython 4.0.0b2 and have immediately hit an issue with SpinCtrl/SpinButton.
I'm running on Linux Mint 18.2

Using this code:

import wx

class MainWindow(wx.Frame):
    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)
        self.panel = wx.Panel(self)
        self.SetSize((200,200))
        sizer=wx.BoxSizer(wx.VERTICAL)
        text1 = wx.StaticText(self.panel,-1,"SpinCtrl")
        self.spin = wx.SpinCtrl(self.panel,-1, size=(100,25),style=wx.SP_VERTICAL)
        text2 = wx.StaticText(self.panel,-1,"SpinButton")
        self.spin2 = wx.SpinButton(self.panel,-1, size=(100,25),style=wx.SP_VERTICAL)
        sizer.Add(text1)
        sizer.Add(self.spin, 0, wx.LEFT, 15)
        sizer.Add((-1, -1), proportion=1)
        sizer.Add(text2)
        sizer.Add(self.spin2, 0, wx.LEFT, 15)
        self.SetSizer(sizer)
        self.Show()

app = wx.App()
win = MainWindow(None)
app.MainLoop()

When running with python2.7/wxpython 3.0.2.0, I get this result:

Whilst running the same code with python3.5.2/wxpython 4.0.0b2, I get this:

I am desperate to get the "old" vertical spin controls back, as they can be sized to take up significantly less space than this "new" version with the +/- controls.
Does anyone know how to get the vertical spin controls back in wxpython 4.0.0b2?

As Robin pointed out, one install was using gtk2 and the other gtk3.
The issue was resolved using the following installation instruction.

sudo pip3 install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk2/ubuntu-16.04 wxPython
