如何在wxpython-phoenix中将事件绑定到功能区按钮单击

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(None, title="wxPython-Phoenix Demo")
        
        panel = wx.Panel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        
        button = wx.Button(panel, label="功能区按钮")
        sizer.Add(button, 0, wx.ALL, 10)
        
        panel.SetSizer(sizer)
        
        button.Bind(wx.EVT_BUTTON, self.on_button_click)
        
    def on_button_click(self, event):
        # 在这里编写功能区按钮单击事件的处理代码
        print("功能区按钮被点击了！")
        
if __name__ == "__main__":
    app = wx.App()
    frame = MyFrame()
    frame.Show()
    app.MainLoop()
