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)

     def textFieldData(self):

     def createCaptionedText(self,panel,label,pos):
         static = wx.StaticText(panel,wx.NewId(),label,pos)
         static.SetBackgroundColour("White")
         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):
         self.textFields["First Name"].SetValue(model.first)
         self.textFields["Last Name"].SetValue(model.last)

     def OnFred(self,event):
         self.model.set("Fred","Flintstones")

     def OnBarney(self,event):
         self.model.set("Barney","Rubble")

     def OnWilma(self,event):
         self.model.set("Wilma","Flintstones")

     def OnBetty(self,event):
         self.model.set("Betty","Rubble")

     def OnCloseWindow(self,event):
         self.Destroy()

 if __name__ == '__main__':
     app = wx.PySimpleApp()
     frame = ModelExample(parent=None,id=-1)
     frame.Show()
     app.MainLoop()
