wxPython Listctrl计数器

Question

如何检测listctrl中的重复值？我想知道如果我输入值，如果它是重复的，计数器将加1，并不会在列表中添加另一行。希望有人能帮忙。我仍然是一个超级noob。 ：d

夫妇的选择，但更容易的选择就是保持你放什么ListCtrl轨道：

class MyForm(wx.Frame): 

    #---------------------------------------------------------------------- 
    def __init__(self): 
     wx.Frame.__init__(self, None, wx.ID_ANY, "List Control Tutorial") 

     self.listitems = set() 
     # or [] in cases where the items aren't hashable 

     .... 

    def add_line(self, event): 
     textval = self.text_ctrl.GetValue() 
     if textval not in self.listitems: 
      line = "Line %s" % self.index 
      self.list_ctrl.InsertStringItem(self.index, line) 
      self.list_ctrl.SetStringItem(self.index, 1, self.text_ctrl.GetValue()) 
      self.index += 1 
      self.listitems.add(textval)
