1. 导入Tkinter库 首先,需要导入Python的Tkinter库。通常使用import tkinter as tk来导入,并简写为tk。 2. 创建Tkinter窗口和标签 然后,创建一个Tkinter窗口和一个标签。标签的初始文本可以设置为任何默认值。 python import tkinter as tk def update_label_text(): # 后续将在这里更新标签文本 pass # 创建主窗...
lb1 = Label(textvariable = var,width = 10,height = 3 )lb1.pack()timer = Timer(1, autoTex...
timeLabel=tk.Label(text=time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())) #设置时间标签,利用 time 模块进行时间的格式化输出 timeLabel.grid(row=3, column=4, sticky=tk.S) 1. 2. 3. 4. 在tkinter 中有一个 after 函数,称为时间触发器,可以定时触发一个函数,这里我们先写一个...
from tkinter import * def change_label_text(): label.config(text="新的文本") root.update() # 强制更新界面 root = Tk() label = Label(root, text="原始文本") label.pack() button = Button(root, text="更改文本", command=change_label_text) button.pack() root.mainloop() 在这个示例中...
