如何基于thefuzz在wx.ComboBox中实现模糊搜索筛选选项

我希望为wx.ComboBox填充大量选项，无需逐一滚动查找，而是通过在ComboBox中输入字符串，利用thefuzz库进行模糊搜索来缩小选项范围。目前已接近实现该功能，但仍存在一些问题：需要捕获更多类型的事件以实现退格、Esc键功能，且无法按预期操作ComboBox中的文本输入框。请问是否有人已经实现过该功能？

以下是我目前的代码：

import wx
from thefuzz import process

class ThingSelector(wx.Frame):
    def __init__(self, parent, title, thing_descriptions):
        super(ThingSelector, self).__init__(parent, title=title, size=(400, 200))
        
        self.thing_descriptions = thing_descriptions

        self.init_ui()

    def init_ui(self):
        panel = wx.Panel(self)

        self.thing_choice = wx.ComboBox(panel, choices=self.thing_descriptions)
        self.thing_choice_block = False
        self.thing_choice_filter = ""
        self.thing_choice.Bind(wx.EVT_TEXT, self.on_text)

        accept_button = wx.Button(panel, label="Accept")
        accept_button.Bind(wx.EVT_BUTTON, self.accept_button_click)

        cancel_button = wx.Button(panel, label="Cancel")
        cancel_button.Bind(wx.EVT_BUTTON, self.on_cancel_button)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.thing_choice, 0, wx.ALL | wx.EXPAND, 5)
        buttons = wx.BoxSizer(wx.HORIZONTAL)
        sizer.Add(buttons, 0, wx.ALL | wx.EXPAND, 5)
        buttons.Add(accept_button, 0, wx.ALL | wx.EXPAND, 5)
        buttons.Add(cancel_button, 0, wx.ALL | wx.EXPAND, 5)

        panel.SetSizer(sizer)

        self.Show()

    def update_choices(self, filter):
        matches = process.extractBests(filter, self.thing_descriptions, limit=10)
        self.thing_choice.SetItems([match[0] for match in matches])
        self.thing_choice.SetInsertionPointEnd()
        self.thing_choice.Popup()

    def on_text(self, event):
        # avoid recursion when I call ChangeValue
        if not self.thing_choice_block:
            self.thing_choice_block = True
            current_text = event.GetString()
            if len(current_text) == 1:
                self.thing_choice_filter += current_text
                self.update_choices(self.thing_choice_filter)
                self.thing_choice_block = False
            else:
                self.thing_choice_filter = ""
                self.thing_choice.ChangeValue(current_text)


    def accept_button_click(self, event):
        selected_thing = ""
        selection = self.thing_choice.GetSelection()
        if selection != wx.NOT_FOUND:
            selected_thing = self.thing_choice.GetString(selection)
        print(selected_thing)
        return

    def on_cancel_button(self, event):
        self.Close()

# Create list of 'thing's:
thing_descriptions = [ "aaa", "bbb", "ccc" ]

# GUI setup
app = wx.App(False)
frame = ThingSelector(None, title="Select Thing", thing_descriptions=thing_descriptions)
app.MainLoop()
