Separate logscreen under Windows

wxPython Users
1

Hi List,

First of I wish you all a happy newyear!

Probably a stupid question, but here it is. I developed an application that
runs OK under Linux, but using windows a separate logscreen appears that
closes when the application ends.

The application uses the logging module (new in Python 2.3), and I do not want
the separate window to appear, I want the output that is displayed in the
separate window to be processed by the logging module.

I have experimented with wxLog, but it doesn't do the things I want.

Cheers,

Hi D.J.

Probably a stupid answer, but I have a utility class:

···

~~~~~~~~~~~~~~~~~~

class StreamRedirector :
    def __init__( self, old_stream, text_ctrl ) :
        self.is_open = True
        self.old_stream = old_stream
        self.text_ctrl = text_ctrl

    # def read !

    def write( self, data ) :
        if self.is_open :
            self.text_ctrl.AppendText( data )

    def flush( self ) :
        pass

    def close( self ) :
        self.is_open = False

    def previous_stream( self ) :
        return self.old_stream
        
~~~~~~~~~~~~~~~~~~

which I use thus:

        # redirect standard output
        sys.stdout = utilswx.StreamRedirector( sys.stdout, self.Log )

where self.Log is a TextCtrl.

Hi Pythonologist,

Thanks, I have checked your solution, but by simply using the proper
statements in the logging module itself it worked already. So I simply was a
moron :wink:

However I am still curious why there is a difference between Windows and
Linux. Probably because the streams stderr and stdout are treated differently
under Windows and Linux.

Thanks anyway

Cheers

The default value of the first parameter to wxApp.__init__ is dependent on platform. On Windows and Mac it will be True which will cause the redirection of sys.stdout and sys.stderr to a file like object that opens a window when there is data written to either of those files. On Unix the default is False and so there is no redirection.
