【问题描述】:
这是我之前的问题wxPython popup from calling imported function 的后续。
我能够找到一种创建 wxPython 对话窗口的方法,以确定我的 GUI 调用的线程是否应该继续执行。我所做的只是在线程本身中创建对话窗口。但是,一旦我通过单击此弹出窗口中的“否”退出线程,我的 GUI 中的关闭按钮变得无响应,并且我无法关闭 GUI 本身。再次感谢您的帮助!
界面代码:
import sys
import os
import re
import subprocess
import threading
import wx
import errno, os, stat, shutil
import extern_func
#this object redirects the external function output to the text box
class RedirectText(object):
def __init__(self,aWxTextCtrl):
self.out=aWxTextCtrl
def write(self,string):
self.out.WriteText(string)
#GUI code here
class progFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, title="functionGUI", size=(800, 600), style=wx.DEFAULT_FRAME_STYLE ^ wx.RESIZE_BORDER)
panel = wx.Panel(self)
#more things....
self.closeButton = wx.Button(panel, wx.ID_OK, "Run", pos=(250, 300))
self.runButton = wx.Button(panel, wx.ID_OK, "Run", pos=(200, 300))
self.out=wx.TextCtrl(panel, style=wx.TE_MULTILINE|wx.VSCROLL|wx.TE_READONLY, pos = (300, 50), size=(500, 200))
#Run button event
self.Bind(wx.EVT_BUTTON, self.OnRun, self.runButton)
#close button event
self.Bind(wx.EVT_BUTTON, self.OnClose, self.closeButton)
#command prompt output to frame
redir=RedirectText(self.out)
sys.stdout=redir
self.Show()
def OnRun(self, event):
t=threading.Thread(target=self.__run)
t.start()
def OnClose(self, event):
self.Destroy()
#external function call
def __run(self):
externFunc()
if __name__ == '__main__':
app = wx.App(False)
progFrame(None)
app.MainLoop()
外部功能代码:
import sys
def externFunc():
print "Starting execution..."
#a bunch of code...
#this is the code for the Yes/No prompt and what introduced the buggy behavior
if(os.path.isdir(mirror_source_path) or os.path.isdir(mirror_dest_path)):
app = wx.App(False)
dlg = wx.MessageDialog(None, "Something bad happened. Continue?","Warning",wx.YES_NO | wx.ICON_QUESTION)
retCode = dlg.ShowModal()
if (retCode == wx.ID_YES):
print "Continuing."
else:
print "Aborted."
return None
sys.exit(0)
dlg.Destroy()
#more function code...
print "Success!"
