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：
>>>
App init...
end mainloop
>>>
窗口显示：
