我在工作时如何使用该作品

Question

运行tkinter的函数冻结。我想使用运行该进程的Tkinter窗口。当运行进度条我想使用tkinterwindow.but我不能，因为它冻结tkinter.how我可以使用根窗口，而time.sleep（10）或其他函数工作

import tkinter.ttk as ttk
import tkinter as tk
import time

progress = 0


def loading(window=None):
    mpb = ttk.Progressbar(window, orient="horizontal", length=200, mode="determinate")
    mpb.place(y=0, x=0)
    mpb["maximum"] = 100
    mpb["value"] = progress
    print(progress)


def incrase():
    global progress
    print(progress)
    progress += 1
    time.sleep(10)  # for example, a function works here and tkinter freezes
    loading()       # i don't want tkinter freezes


root = tk.Tk()
loading(root)
ttk.Button(root, text='increase', command=incrase).place(x=0, y=25, width=90)

root.mainloop()

谢谢你的回答

您应该使用after（），通过它可以安排load（）函数在一段时间后调用。

下面是如何在程序中使用它：

import tkinter.ttk as ttk
import tkinter as tk
import time

progress = 0


def loading(window):
    mpb = ttk.Progressbar(window, orient="horizontal", length=200, mode="determinate")
    mpb.place(y=0, x=0)
    mpb["maximum"] = 100
    mpb["value"] = progress
    print(progress)


def incrase():
    global root
    global progress
    print(progress)
    progress += 1
    root.after(10, loading(root))  # schedule loading() 



root = tk.Tk()
loading(root)
ttk.Button(root, text='increase', command=incrase).place(x=0, y=25, width=90)

root.mainloop()
