wxPython：将多个小部件 - Frame e Panel - 绑定到同一个处理程序

Question

让我们假设有这个代码：

#!/usr/bin/python
# _*_ coding: utf-8 _*_
import wx

class wxappsubclass(wx.App):
  def OnInit(self):
    frame=wxframesubclass(None, -1, 'MyName')
    frame.Show(True)
    return True

class wxframesubclass(wx.Frame):
  def __init__(self, parent, id, title):
    wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, size=(320, 240))
    panel=panel1(self)
    menubar=wx.MenuBar()
    menufile=wx.Menu()
    ExitItem=menufile.Append(wx.NewId(), '&Exit\tCtrl+Q', "Exit")
    menubar.Append(menufile, '&File')
    self.SetMenuBar(menubar)

    ## BINDING ##
    self.Bind(wx.EVT_MENU, self.CloseProgramFromFrame, ExitItem)

  def CloseProgramFromFrame(self, event):
    self.Close(True)

class panel1(wx.Panel):
  def __init__(self, parent):
    wx.Panel.__init__(self, parent, -1)
    ID_EXIT_BUTTON=wx.NewId()
    ExitButton=wx.Button(self, wx.NewId(), label="Exit")
    self.Bind(wx.EVT_BUTTON, self.CloseProgramFromPanel, ExitButton)

  def CloseProgramFromPanel(self, event):
    parente=self.GetParent()
    parente.Destroy()

if __name__ == '__main__':
  app=wxappsubclass()
  app.MainLoop()

现在，如果我想从 class "panel1()" 绑定相同的事件处理程序（本例中的 "CloseProgramFromFrame" ）怎么办？

即：我想删除 "panel1" 中的 "CloseProgramFromPanel()" 方法，然后绑定 "Exit" 按钮 - 即 "panel1()" 中的 EVT_BUTTON - 到 "CloseProgramFromFrame()"方法中的"wxframesubclass()"，怎么办？我有点困惑...

一种可能的方法是：

#!/usr/bin/python
# _*_ coding: utf-8 _*_
import wx

class wxappsubclass(wx.App):
  def OnInit(self):
    frame=wxframesubclass(None, -1, 'MyName')
    frame.Show(True)
    return True

class wxframesubclass(wx.Frame):
  def __init__(self, parent, id, title):
    wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, size=(320, 240))
    self.panel=panel1(self)
    menubar=wx.MenuBar()
    menufile=wx.Menu()
    ExitItem=menufile.Append(wx.NewId(), '&Exit\tCtrl+Q', "Exit")
    menubar.Append(menufile, '&File')
    self.SetMenuBar(menubar)

    ## BINDING ##
    self.Bind(wx.EVT_MENU, self.CloseProgramFromFrame, ExitItem)
    self.Bind(wx.EVT_BUTTON, self.CloseProgramFromFrame, self.panel.ExitButton)

  def CloseProgramFromFrame(self, event):
    self.Close(True)

class panel1(wx.Panel):
  def __init__(self, parent):
    wx.Panel.__init__(self, parent, -1)
    ID_EXIT_BUTTON=wx.NewId()
    self.ExitButton=wx.Button(self, wx.NewId(), label="Exit")

if __name__ == '__main__':
  app=wxappsubclass()
  app.MainLoop()
