title: Best way to get the name of a button that called an event?
body: <p>In the following code (inspired by <a href="http://www.daniweb.com/code/snippet508.html" rel="nofollow noreferrer">this</a> snippet), I use a single event handler <code>buttonClick</code> to change the title of the window. Currently, I need to evaluate if the Id of the event corresponds to the Id of the button. If I decide to add 50 buttons instead of 2, this method could become cumbersome. Is there a better way to do this?</p>
  
  <pre><code>import wx
  
  class MyFrame(wx.Frame):
      def __init__(self):
          wx.Frame.__init__(self, None, wx.ID_ANY, 'wxBitmapButton',
              pos=(300, 150), size=(300, 350))
          self.panel1 = wx.Panel(self, -1)
  
          self.button1 = wx.Button(self.panel1, id=-1,
              pos=(10, 20), size = (20,20))
          self.button1.Bind(wx.EVT_BUTTON, self.buttonClick)
  
          self.button2 = wx.Button(self.panel1, id=-1,
              pos=(40, 20), size = (20,20))
          self.button2.Bind(wx.EVT_BUTTON, self.buttonClick)
  
          self.Show(True)
  
      def buttonClick(self,event):
          if event.Id == self.button1.Id:
              self.SetTitle("Button 1 clicked")
          elif event.Id == self.button2.Id:
              self.SetTitle("Button 2 clicked")            
  
  application = wx.PySimpleApp()
  window = MyFrame()
  application.MainLoop()
