Passing wxPython objects as multiprocessor arguments

I'm currently writing a program in python w开发者_JAVA百科ith a gui using wxpython. The program has a function which evaluates several pythonscripts and will therefore hang up the gui. I am trying to use a separate process for this function. The problem is that the function needs a few things from the ui; a listctrl and a textctrl, to update the information about the scripts that have been run. The following error is received when trying to pass wxpython objects to the process

PicklingError: Can't pickle <type 'PySwigObject'>: attribute lookup __builtin__.PySwigObject failed

Method that creates and starts the process:

def CreateProcess():
    q = Queue()
    q.put(gui.caselist)
    q.put(gui.textlog)
    p = Process(target=runScripts, args=(q,))
    p.start()

Part of the method that is being ran by the process:

def runScripts(q):
    caselist = q.get()
    text = q.get()

Basically, you can't. You need to pass the results back and let the GUI thread update the listctrl and textctrl.

See this mailing list thread for information about the pickling error.
