我主要为技术精通的人写一个小工具,例如程序员,工程师等等.由于这些工具通常会随着时间的推移而改进,因此我知道将会有未处理的异常,用户不会介意.我希望用户能够向我发送回溯,以便我可以检查发生了什么,并可能改进应用程序. @H_502_2@我通常做wxPython编程,但我最近做了一些Java.我已经把TaskDialog类挂接到Thread.UncaughtExceptionHandler(),我对结果很满意.特别是它可以捕获和处理任何线程的异常：

@H_502_2@我在wxPython中做了类似的工作很长一段时间.然而：

@H_502_2@>我不得不写一个装饰器,以便能够从另一个线程打印异常.
>即使在功能上,结果也相当丑陋.

@H_502_2@这里是Java和wxPython的代码,所以你可以看到我做了什么：

@H_502_2@Java的：

@H_502_2@wxPython的：

import StringIO
import sys
import traceback
import wx
from wx.lib.delayedresult import startWorker


def thread_guard(f):
    def thread_guard_wrapper(*args,**kwargs) :
        try:
            r = f(*args,**kwargs)
            return r
        except Exception:
            exc = sys.exc_info()
            output = StringIO.StringIO()
            traceback.print_exception(exc[0],exc[1],exc[2],file=output)
            raise Exception("<THREAD GUARD>\n\n" + output.getvalue())
    return thread_guard_wrapper

@thread_guard
def thread_func():
    return 1 / 0

def thread_done(result):
    r = result.get()
    print r


class MainWindow(wx.Frame):
    def __init__(self,*args,**kwargs):
        wx.Frame.__init__(self,**kwargs)

        self.panel = wx.Panel(self)
        self.button = wx.Button(self.panel,label="Throw!")
        self.button.Bind(wx.EVT_BUTTON,self.OnButton)

        self.sizer = wx.BoxSizer()
        self.sizer.Add(self.button)

        self.panel.SetSizerAndFit(self.sizer)  
        self.Show()

    def OnButton(self,e):
        startWorker(thread_done,thread_func)

app = wx.App(True)
win = MainWindow(None,size=(600,400))
app.MainLoop()

@H_502_2@现在的问题：

@H_502_2@我可以轻松地做一些类似于wxPython中的Java解决方案的东西吗？或者也许,在Java或wxPython中有更好的方法吗？
