Newbie Question, Is it possible todo DDE with wxPython

wxPython Users

Hello Everyone

I'm a bit new to wxPython although i've been programming in C++ and C for sometime. In C++ with visual studio 6 on windows it was possible to send and receive events from the entire system, for example it was possible to send keypresses and mouse events to the system from my program without the user having to have pressed the mouse or a key.

I am now writing in wxPython for both windows and Linux (Well I want my program to run on both the same anyway, i'm actually writing it on linux)

Can anyone tell me, is it possible to send keyboard events to the system from wxPython? (And if so can you point me in the right direction)

Thankyou
Tim

Perhaps there is a better way, but in linux I fake key events with the program
that follows. I guess your program will have to detect whether it is under
linux/windows and, in windows, use Python for Windows Extensions download | SourceForge.net

from distutils.core import setup, Extension

modulekey = Extension('key',

                    libraries = ['Xtst'],
                    library_dirs = ['/usr/X11R6/lib'],

setup (name = 'PackageKey',
       version = '1.0',
       description = 'This is a key package',
       ext_modules = [modulekey])

actually using:---------------

import key
key.makeev(0xFFBF) # fake 'F1' key, for instance
