我不知道我是否使用正确的代码来做到这一点。我写了一个小脚本来查找硬盘中的文件夹:
import sys
from tkinter import *
from tkinter import ttk
import threading
import os
mGui = Tk()
mGui.geometry('450x80')
mGui.title('Copy folder')
progressbar = ttk.Progressbar(orient=HORIZONTAL, length=200, mode='determinate')
progressbar.pack(side="bottom")
xe = 'progresscache'
def handle_click():
progressbar.start()
def searcher():
for root, dirs, files in os.walk(r'c:'):
for name in dirs:
if name == xe:
print ("find !")
progressbar.stop()
t = threading.Thread(target=searcher)
t.start()
dirBut = Button(mGui, text='Go find !', command = handle_click)
dirBut.pack()
mGui.mainloop()
经过多次尝试,当我点击我的boutton时,我仍然需要冻结GUI
所以我决定用一个主题来调用这个动作
我不知道我们是否应该这样做以避免冻结...
好吧,一切似乎都没有冻结......
现在,我想用我的代码做一个类, 但每次我收到线程错误 这是我的代码:
我的班级Searcher.py(在Appsave文件夹中)
import os
import threading
class Searcher:
def recherche(zeFolder):
for root, dirs, files in os.walk(r'c:'):
for name in dirs:
if name == zeFolder:
print ("Finded !")
progressbar.stop()
threading.Thread(target=recherche).start()
我的主要.py
# -*- coding: utf-8 -*-
import sys
from tkinter import *
from tkinter import ttk
import threading
import os
from Appsave.Searcher import Searcher
mGui = Tk()
mGui.geometry('450x80')
mGui.title('Djex save')
progressbar = ttk.Progressbar(orient=HORIZONTAL, length=200, mode='determinate')
progressbar.pack(side="bottom")
xe = 'progresscache'
la = Searcher
def handle_click():
progressbar.start()
la.recherche(xe)
dirBut = Button(mGui, text='Go find !', command = handle_click)
dirBut.pack()
mGui.mainloop()
这是输出错误
Exception in thread Thread-1:
Traceback (most recent call last):
File "C:\python34\lib\threading.py", line 921, in _bootstrap_inner
self.run()
File "C:\python34\lib\threading.py", line 869, in run
self._target(*self._args, **self._kwargs)
TypeError: recherche() missing 1 required positional argument: 'zeFolder'
我希望能够找到足够详细的问题来寻求帮助,谢谢
答案 0 :(得分:5)
您应该尝试子类化Thread
,如下所示:
class Searcher(threading.Thread):
def __init__(self, zeFolder, progressbar):
super(Searcher, self).__init__()
self.zeFolder = zeFolder
self.progressbar = progressbar
def run(self):
for root, dirs, files in os.walk(r'c:'):
for name in dirs:
if name == self.zeFolder:
print ("Finded !")
self.progressbar.stop()
然后,这样称呼它:
xe = 'progresscache'
la = Searcher(xe, progressbar)
def handle_click():
progressbar.start()
la.start()
而不是:
xe = 'progresscache'
la = Searcher
def handle_click():
progressbar.start()
la.recherche(xe)
希望它有所帮助!
