Python tkinter中的进度条不工作

我正在写一个小应用程序来复制一些文件。我几乎做了我想要的所有东西，但有三件事：

1） “复制”选项处于运动状态时要移动的进度条。我可以展示它，但它不会反应

我用这个来表示：

self.p = ttk.Progressbar(self, orient=HORIZONTAL, length=300, mode='indeterminate')
self.p.grid(row=5)

然后在按下按钮后调用的另一个def中启动：

 self.p.start()

 shutil.copytree(self.source_direcotry0, self.cam0)
 shutil.copytree(self.source_direcotry1, self.cam1)
 shutil.copytree(self.source_direcotry2, self.cam2)

 self.p.stop()

不幸的是，复制发生了，但条根本没有移动

2） 第二个问题与我在应用程序窗口底部显示的信息栏有关：

self.status = Label(self.master, text="Waiting for process to start...", bd=1, relief=SUNKEN, anchor=W)
self.status.pack(side=BOTTOM, fill=X)

然后，当在开始时调用相同的复制def时，我有：

self.status['text'] = "Files are being copyied, have patience ;)".format(self.status)

状态没有改变，这很奇怪，因为在这个def的末尾，我还有相同的命令来改变状态，这个命令有效：

self.status['text'] = "Files have been copyied".format(self.status)

3） 我似乎无法附加图片我已检查了各种不同的选项，但它们似乎都不起作用，此处显示的图片似乎试图显示某些内容（窗口变大），但图片不可见：

 self.img = ImageTk.PhotoImage(Image.open("az.png"))
 self.panel = Label(self, image=self.img, bg="#E6E6E6")
 self.display = self.img
 self.panel.grid(row=8)

我有点不确定为什么会这样，以防万一，还有更多信息，我在这里发布完整的代码：

正如同时出现的其他问题一样，我似乎无法改变输入框周围按钮和边框的背景颜色。我读到这可能是因为使用MacOS平台，是吗？有什么解决办法吗？

我在我的一个老项目中压实了装载杆。我发现的唯一方法是在一个新线程中调用处理调用的进度条，并将工作密集型函数从这个线程调用到另一个新线程中

让一个单独的线程来处理UI线程以外的UI元素是不好的做法，包括启动和停止进度条；然而，它确实可以工作，我已经使用这个项目做了几个月的零问题相当繁重的处理

在这里，进度条在一个小脚本中工作，在W10 64位上使用Python 3.5.2

from tkinter import *
import tkinter.ttk as ttk
import threading
import time

class Main_Frame(object):
    def __init__(self, top=None):
        # save root reference
        self.top = top
        # set title bar
        self.top.title("Loading bar example")

        # start button calls the "initialization" function bar_init, you can pass a variable in here if desired
        self.start_button = ttk.Button(top, text='Start bar', command=lambda: self.bar_init(2500))
        self.start_button.pack()

        # the progress bar will be referenced in the "bar handling" and "work" threads
        self.load_bar = ttk.Progressbar(top)
        self.load_bar.pack()

        # run mainloop
        self.top.mainloop()

    def bar_init(self, var):
        # first layer of isolation, note var being passed along to the self.start_bar function
        # target is the function being started on a new thread, so the "bar handler" thread
        self.start_bar_thread = threading.Thread(target=self.start_bar, args=(var,))
        # start the bar handling thread
        self.start_bar_thread.start()

    def start_bar(self, var):
        # the load_bar needs to be configured for indeterminate amount of bouncing
        self.load_bar.config(mode='indeterminate', maximum=100, value=0)
        # 8 here is for speed of bounce
        self.load_bar.start(8)
        # start the work-intensive thread, again a var can be passed in here too if desired
        self.work_thread = threading.Thread(target=self.work_task, args=(var,))
        self.work_thread.start()
        # close the work thread
        self.work_thread.join()
        # stop the indeterminate bouncing
        self.load_bar.stop()
        # reconfigure the bar so it appears reset
        self.load_bar.config(value=0, maximum=0)

    def work_task(self, wait_time):
        for x in range(wait_time):
           time.sleep(0.001)

if __name__ == '__main__':
    # create root window
    root = Tk()
    # call Main_Frame class with reference to root as top
    Main_Frame(top=root)

Edit2：我已经找到了一种方法来制作图片和按钮背景：picture:render=PhotoImage（file=“az.gif”）img=Label（self，image=render，bg=“#e6e6”）img.image=render img.grid（row=8）和按钮，方法是添加“highlightbackground”：goButton=Button（self，text=“Go！”，command=self.copy，highlightbackground=“#e6e6”）但我仍然无法理解此进度条，没有任何提示？您应该在调用

self.p.start（）

后尝试在新线程上启动复制函数。复制可能会阻止UI线程设置进度条的动画。我尝试过线程，但无法使其工作，即使使用线程时文件也没有被复制。可能是我实现错了，但我找不到正确的方法<代码>self.p.start（）root.update_idletasks（）用于范围（12）内的x：t=threading.Thread（target=self.copy2）t.deamon=True t.start（）self.p.stop（）然后更新所有

shutil.copytree（self.source\u direcotry0，self.cam0）

已移动到名为

copy2

的新的

def

。非常感谢您的帮助。我需要一些时间来消化并尝试它，但如果再次有疑问，我将返回。再次感谢！没问题，如果您还有任何问题，请随时发表意见，我会尽力帮助您的！：）
