将wxPython对象作为多处理器参数传递 [英] Passing wxPython objects as multiprocessor arguments

问题描述

我目前正在使用wxpython用gui编写python程序.该程序具有评估多个pythonscripts的功能，因此将挂断gui.我正在尝试为此功能使用单独的过程.问题在于该函数需要ui中的一些内容； listctrl和textctrl，以更新有关已运行脚本的信息.尝试将wxpython对象传递给进程时收到以下错误

I'm currently writing a program in python with 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

创建并启动该过程的方法:

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()

该过程正在运行的方法的一部分:

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

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

推荐答案

基本上，您不能.您需要将结果传回，并让GUI线程更新listctrl和textctrl.

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