wxPython入门练习代码 四

自定义Model文件abtractmodel.py:

class AbstractModel(object):

    def __init__(self):
        self.listeners = []

    def addListener(self, listenerFunc):
        self.listeners.append(listenerFunc)

    def removeListener(self, listenerFunc):
        self.listeners.remove(listenerFunc)

    def update(self):
        for eachFunc in self.listeners:
            eachFunc(self)

实例调用MVC文件ModelExample.py:

#!usr/bin/env python

    def __init__(self,first="",last=""):
        abstractmodel.AbstractModel.__init__(self)

        textPos = (pos[0]+75,pos[1])
        self.textFields[label] = wx.TextCtrl(panel,wx.NewId(),
                "",size=(100,-1),pos=textPos,
                style=wx.TE_READONLY)
                
    def OnUpdate(self,model):
