Python: combining log and wx so the log flow redirects to stdout / stderr frame

Question

Here's the thing:

I am trying to combine a registration module with the redirection function wx.App (). My intention is to register the AND file in stderr. But I want stderr / stdout to be redirected to a separate frame, like the wx.App function.

My test code is:

import logging
import wx

class MyFrame(wx.Frame):
    def __init__(self):
        self.logger = logging.getLogger("main.MyFrame")
        wx.Frame.__init__(self, parent = None, id = wx.ID_ANY, title = "MyFrame")
        self.logger.debug("MyFrame.__init__() called.")

    def OnExit(self):
        self.logger.debug("MyFrame.OnExit() called.")

class MyApp(wx.App):
    def __init__(self, redirect):
        self.logger = logging.getLogger("main.MyApp")
        wx.App.__init__(self, redirect = redirect)
        self.logger.debug("MyApp.__init__() called.")

    def OnInit(self):
        self.frame = MyFrame()
        self.frame.Show()
        self.SetTopWindow(self.frame)
        self.logger.debug("MyApp.OnInit() called.")
        return True

    def OnExit(self):
        self.logger.debug("MyApp.OnExit() called.")

def main():
    logger_formatter = logging.Formatter("%(name)s\t%(levelname)s\t%(message)s")
    logger_stream_handler = logging.StreamHandler()
    logger_stream_handler.setLevel(logging.INFO)
    logger_stream_handler.setFormatter(logger_formatter)
    logger_file_handler = logging.FileHandler("test.log", mode = "w")
    logger_file_handler.setLevel(logging.DEBUG)
    logger_file_handler.setFormatter(logger_formatter)
    logger = logging.getLogger("main")
    logger.setLevel(logging.DEBUG)
    logger.addHandler(logger_stream_handler)
    logger.addHandler(logger_file_handler)
    logger.info("Logger configured.")

    app = MyApp(redirect = True)
    logger.debug("Created instance of MyApp. Calling MainLoop().")
    app.MainLoop()
    logger.debug("MainLoop() ended.")
    logger.info("Exiting program.")

    return 0

    main()

wx.App , stdout/stderr , , sys.stdout sys.stderr, , sys.stdout sys.stderr, ,

print "this will go to wx msg frame"
sys.stdout.write("yes it goes")
sys.stderr.write("... and this one too")

, wxApp , streamhandler () sys.stderr sys.stdout , wxApp, wx.App streap, app = MyApp(redirect = True) , .

sys.stdout sys.stderr .

class LogginRedirectHandler(logging.Handler):
        def __init__(self,):
            # run the regular Handler __init__
            logging.Handler.__init__(self)

        def emit(self, record):
            sys.stdout.write(record.message)

loggingRedirectHandler = LogginRedirectHandler()
logger_file_handler.setLevel(logging.DEBUG)
logger.addHandler(loggingRedirectHandler)
