如何在wxPython中删除StaticBox？

import wx
import wx.lib.statbox as statbox

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        super(MyFrame, self).__init__(parent, title=title)

        # 创建主面板
        self.panel = wx.Panel(self)

        # 创建StaticBox和相关控件
        self.static_box = wx.StaticBox(self.panel, label="StaticBox")
        self.static_box_sizer = wx.StaticBoxSizer(self.static_box, wx.VERTICAL)
        self.static_text = wx.StaticText(self.static_box, label="Hello, World!")
        self.static_box_sizer.Add(self.static_text, 0, wx.ALL, 10)

        # 创建按钮用于删除StaticBox
        self.delete_button = wx.Button(self.panel, label="删除StaticBox")
        self.delete_button.Bind(wx.EVT_BUTTON, self.on_delete_button_clicked)

        # 将StaticBox和按钮添加到主面板中
        self.panel_sizer = wx.BoxSizer(wx.VERTICAL)
        self.panel_sizer.Add(self.static_box_sizer, 0, wx.ALL, 10)
        self.panel_sizer.Add(self.delete_button, 0, wx.ALL, 10)
        self.panel.SetSizerAndFit(self.panel_sizer)

    def on_delete_button_clicked(self, event):
        # 删除StaticBox和相关控件
        self.static_box_sizer.Clear(True)
        self.panel_sizer.Layout()
        self.panel.Layout()

if __name__ == "__main__":
    app = wx.App()
    frame = MyFrame(None, "删除StaticBox示例")
    frame.Show()
    app.MainLoop()
