如何让 wxListCtrl 使用原生 macos 实现？

Question

I am trying to have my wxListCtrl use the native implementation on macos, but I'm only getting the generic implementation.

According to the wxWiki :

Starting with wxWidgets 2.8 (wxMac), wxListCtrl uses a native implementation for report mode, and uses a generic implementation for other modes.

I have already set my wxListCtrl to LC_REPORT , but I still get the generic implementation.

What am I doing wrong?

(I'm using Python 3.8.2 on macOS 10.15.4 Catalina, and tested with both stable wxPython 4.0.7 and the latest snapshot build wxPython-4.1.0a1.dev4650+de25f309-cp38-cp38-macosx_10_9_x86_64.whl )

Minimal example

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import wx

class MyForm(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, 'Example')

        panel = wx.Panel(self, wx.ID_ANY)
        self.index = 0

        self.list_ctrl = wx.ListCtrl(panel, style=wx.LC_REPORT)
        self.list_ctrl.InsertColumn(0, 'Title')

        btn = wx.Button(panel, label='Add row')
        btn.Bind(wx.EVT_BUTTON, self.add_line)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.list_ctrl, 0, wx.ALL|wx.EXPAND, 5)
        sizer.Add(btn, 0, wx.ALL|wx.CENTER, 5)
        panel.SetSizer(sizer)

    def add_line(self, event):
        line = "Row %s" % self.index
        self.list_ctrl.InsertItem(self.index, line)
        self.index += 1


if __name__ == '__main__':
    app = wx.App()
    frame = MyForm()
    frame.Show()
    app.MainLoop()

Mac 下原生的wxListCtrl实现被证明是有太多问题，因此在 wx 3 中被删除。 如果可以，请考虑使用wxDataViewCtrl ，它是 Mac 下原生的并且通常可用，即使它与通用版本相比仍然有一些限制，因为原生 API 特性。
