AddMany用於佈局框架中的按鈕。如何在點擊時捕獲事件？

Question

import wx 

class FrontMenu(wx.Frame): 

    def __init__(self, parent, title): 
     super(FrontMenu, self).__init__(parent, title=title, size=(400, 300)) 
     self.InitUI() 
     self.Centre() 
     self.Show() 

    def InitUI(self): 
     menubar = wx.MenuBar() 
     fileMenu = wx.Menu() 
     menubar.Append(fileMenu, '&File') 
     self.SetMenuBar(menubar) 
     vbox = wx.BoxSizer(wx.VERTICAL) 
     gs = wx.GridSizer(4, 1, 0, 0) 

     gs.AddMany([ 
      (wx.Button(self, label='Create New Audit.'), 0, wx.EXPAND), 
      (wx.Button(self, label='View Previous Audits.'), 0, wx.EXPAND), 
      (wx.Button(self, label='Add New Engineer.'), 0, wx.EXPAND), 
      (wx.Button(self, label='Close Application.'), 0, wx.EXPAND) 
      ]) 

當使用AddMany方法我怎麼捕捉按鍵事件？ 當我一次添加按鈕1時，我可以達到此目的。

Answer 1

分配ID給您的按鈕：

wx.Button(self, id=SOME_INTEGER, label=... 

添加事件處理程序：

self.Bind(wx.EVT_BUTTON, self.on_button) 

，並在處理程序檢查事件源ID：

def on_button(self, evt): 
    evt.Skip() 
    if SOME_INTEGER == evt.GetId(): 
     # do something.

這使我指出了正確的方向。以下是現在可用的代碼。
