The style parameter is set thus:

        if sliderHor:
            style = wx.SL_HORIZONTAL | wx.SL_AUTOTICKS | \
                wx.SL_BOTTOM
            sizeW = (size, -1)
        else:
            style = wx.SL_VERTICAL | wx.SL_AUTOTICKS | \
                wx.SL_BOTTOM | wx.SL_INVERSE
            sizeW = (-1, size)

Although it doesn't explicitly say so in the documentation, I believe
that SL_BOTTOM is only valid in conjunction with SL_HORIZONTAL.

AFAICT, for SL_VERTICAL, you have to choose either SL_LEFT or SL_RIGHT.
