wxpython-输出重定向

2、重定向输出

输出由控制台重定向到窗口

mport wx

import sys

class Frame(wx.Frame):

   def __init__(self,parent,id,title):

       print "frame init ..."

       wx.Frame.__init__(self,parent,id,title)

class App(wx.App):

   def __init__(self,redirect=True,filename=None):

       print "App init..."

       wx.App.__init__(self,redirect,filename)

   def OnInit(self):

       print "oninit..."

       self.frame=Frame(parent=None,id=-1,title='hello')

       self.frame.Show()

       self.SetTopWindow(self.frame)

       print sys.stderr,"error message"

       return True

   def OnExit(self):

       print "OnExit"

if __name__=='__main__':

   app=App(redirect=True)

   print "begin mainloop"

   app.MainLoop()

   print "end mainloop"

控制台显示：

>>>
