这是我在python CMD中运行的代码:
import mailbox
import pprint
f = open("results.txt","w")
mbox = mailbox.mbox('c:\documents and settings\student\desktop\mail\mailall.mbox')
count = 0
for msg in mbox:
pprint.pprint(msg._headers, stream = f)
if msg['Delivered-To'] == 'example@example.co.uk':
count += 1
f.close()
print(count)
然而,当我在GUI中运行它时,它会导致GUI崩溃(闪烁黑色并且不会打开)。这是GUI:
import datetime
from tkinter import filedialog
import tkinter
class App:
def __init__(self, master):
self.master = master
# call start to initialize to create the UI elemets
self.start()
def start(self):
self.master.title("Extract Email Headers")
self.now = datetime.datetime.now()
# CREATE A TEXT/LABEL
# create a variable with text
label01 = "Please select the .mbox file you would like to analyse"
# put "label01" in "self.master" which is the window/frame
# then, put in the first row (row=0) and in the 2nd column (column=1),
# align it to "West"/"W"
tkinter.Label(
self.master, text=label01).grid(row=0, column=0, sticky=tkinter.W)
# CREATE A TEXTBOX
self.filelocation = tkinter.Entry(self.master)
self.filelocation["width"] = 60
self.filelocation.focus_set()
self.filelocation.grid(row=1, column=0)
# CREATE A BUTTON WITH "ASK TO OPEN A FILE"
# see: def browse_file(self)
self.open_file = tkinter.Button(
self.master, text="Browse...", command=self.browse_file)
# put it beside the filelocation textbox
self.open_file.grid(row=1, column=1)
# now for a button
self.submit = tkinter.Button(
self.master, text="Execute!", command=self.start_processing,
fg="red")
self.submit.grid(row=3, column=0)
def start_processing(self):
import mailbox
import pprint
f = open("results.txt","w")
mbox = mailbox.mbox('c:\documents and settings\student\desktop\mail\mailall.mbox')
count = 0
for msg in mbox:
pprint.pprint(msg._headers, stream = f)
if msg['Delivered-To'] == 'example@example.co.uk':
count += 1
f.close()
print(count)
def browse_file(self):
# put the result in self.filename
self.filename = filedialog.askopenfilename(title="Open a file...")
# this will set the text of the self.filelocation
self.filelocation.insert(0, self.filename)
root = tkinter.Tk()
app = App(root)
root.mainloop()
如果我把流程代码拿出并放入"传递",GUI工作,所以我知道它的代码正在抛弃它。感谢
