wxPython:有没有办法在wx.dataview.DataViewListCtrl的列标题中显示排序箭头指示器？

import wx
import wx.dataview as dv

# 创建自定义渲染器类
class SortHeaderRenderer(dv.DataViewCustomRenderer):
    def __init__(self):
        dv.DataViewCustomRenderer.__init__(self)

    # 绘制列标题
    def Render(self, rect, dc, state):
        dc.SetBackground(wx.Brush(wx.Colour(240, 240, 240)))  # 设置背景颜色
        dc.SetTextForeground(wx.BLACK)  # 设置文字颜色
        dc.DrawRectangle(rect)  # 绘制矩形

        if state & dv.DATAVIEW_CELL_SELECTED:  # 如果处于选中状态
            dc.SetFont(wx.Font(9, wx.DEFAULT, wx.NORMAL, wx.BOLD))  # 设置加粗字体
        else:
            dc.SetFont(wx.Font(9, wx.DEFAULT, wx.NORMAL, wx.NORMAL))  # 设置普通字体

        # 绘制标题文字
        dc.DrawText("Column Header", rect.x + 5, rect.y + 5)

        # 绘制排序箭头指示器
        if state & dv.DATAVIEW_COL_SORTED:  # 如果列处于排序状态
            sort_order = self.GetDataViewColumn().GetSortOrder()
            if sort_order == dv.DATAVIEW_SORT_ASCENDING:
                dc.DrawText(" ▲", rect.x + rect.width - 20, rect.y + 5)  # 绘制升序箭头
            elif sort_order == dv.DATAVIEW_SORT_DESCENDING:
                dc.DrawText(" ▼", rect.x + rect.width - 20, rect.y + 5)  # 绘制降序箭头

    # 获取渲染器大小
    def GetSize(self):
        return wx.Size(100, 25)

# 创建应用程序对象
app = wx.App()
frame = wx.Frame(None, wx.ID_ANY, "Sort Indicator Example", size=(400, 300))

# 创建wx.dataview.DataViewListCtrl控件并设置渲染器
list_ctrl = dv.DataViewListCtrl(frame)
header_renderer = SortHeaderRenderer()
list_ctrl.GetMainWindow().SetHeaderAttr(header_renderer)

# 添加列
list_ctrl.AppendTextColumn("Column 1")
list_ctrl.AppendTextColumn("Column 2")

# 添加数据
list_ctrl.AppendItem(["Data 1", "Data 2"])
list_ctrl.AppendItem(["Data 3", "Data 4"])

frame.Show()
app.MainLoop()
