我觉得Progressbar超可爱，这个就很适合用在要做测验之类的介面上。

• Progressbar的方法
• mode模式

Progressbar常用参数

语法:Progressbar( master,,options, …)

import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()

root.title('cuteluluWindow')
root.configure(bg="#7AFEC6")
root.iconbitmap('heart_green.ico')
root.geometry('300x150')

pb1 = ttk.Progressbar(root)
pb1.pack(pady=20)
pb1["maximum"] =100
pb1["value"] = 50

pb2 = ttk.Progressbar(root,orient='vertical',
                  length=130,mode ="determinate")
pb2.pack(pady=20)

pb2["maximum"]=100
pb2["value"]=30

root.mainloop()

动画设计

用update() 方法就可以做出动画的Progressbar，视窗会重新依据 value 值重绘，这样就可以达到动画效果。

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

root = tk.Tk()
root.title('cuteluluWindow')
root.configure(bg="#7AFEC6")
root.iconbitmap('heart_green.ico')
root.geometry('300x100')

def running():
    for i in range(100):
        pb["value"] = i+1
        root.update()
        time.sleep(0.03)

pb = ttk.Progressbar(root, length=150,
                 mode="determinate", orient='horizontal')
pb.pack(padx=10,pady=10)
pb["maximum"] = 100
pb["value"] = 0

b = tk.Button(root, text="Running",command=running)
b.pack(pady=18)

root.mainloop()

执行结果⬇⬇⬇

Progressbar的方法

import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()
root.title('cuteluluWindow')
root.configure(bg="#7AFEC6")
root.iconbitmap('heart_green.ico')
root.geometry('300x100')

def Start():
    pb.start()
def Stop():
    pb.stop()

pb = ttk.Progressbar (root, length=200, mode="determinate",
                  orient='horizontal')
pb.pack(padx=5, pady=10)
pb["maximum"] = 100
pb["value"] = 0

bR=tk.Button (root, text="Run", command=Start)
bR.pack(side='left', padx=5, pady=10)
bS = tk.Button(root, text="Stop", command=Stop)
bS.pack (side='left', padx=5, pady=10)

root.mainloop()

执行结果⬇⬇⬇

按Run就开始跑，按Stop就会重新跑

mode模式

pb = ttk.Progressbar (root, length=200,mode="indeterminate", orient='horizontal') 

执行结果⬇⬇⬇

今天的也很简单，也可以结合其他元件试试看~~
