Python图形编程探索系列-08-再次认识标签

标签的各种属性

**代码展示：**
```
import tkinter as tk
root = tk.Tk()
root.geometry = '500x300'
label1 = tk.Label(root, text='龙王手游', width=50, height=10, bd=10)
label1.config(fg='white', bg='black', relief=tk.RAISED, font=('楷体', 10, 'overstrike'))

label2 = tk.Label(root, text='标签2', relief=tk.GROOVE, width=50, height=10, bd=2)

label2.config(fg='red', compound=tk.LEFT, bitmap='error', bg='yellow', font=('隶书', 10, 'bold'))

label3 = tk.Label(root, text='标签3', compound=tk.LEFT, bitmap='info', relief=tk.SUNKEN, width=50, height=10, bd=2)

label3.config(fg='white', bg='green', font=('隶书', -10, 'bold'))

label4 = tk.Label(root, text='标签4', width=50, height=10, bd=2)

label4.config(fg='white', bg='black', font=('楷书', -10, 'bold'))

label5 = tk.Label(root, text='标签5', width=50, height=10)

label5.config(fg='red', bg='yellow', bd=2, font=('隶书', 10, 'bold'))

label6 = tk.Label(root, text='标签6', width=50, height=10, bd=2)

label6.config(fg='white', bg='green', font=('隶书', 10, 'bold'))

label7 = tk.Label(root, text='标签7', width=50, height=10, bd=2)

label7.config(fg='white', bg='black', font=('隶书', 10, 'bold'))

label8 = tk.Label(root, text='标签8', width=50, height=10, bd=2)

label8.config(fg='red', bg='yellow', font=('隶书', 10, 'bold'))

label9 = tk.Label(root, text='标签9', width=50, height=10)

label9.config(fg='white', bg='green', bd=2, font=('隶书', 10, 'bold'))

label1.grid(row=0, column=0, ipadx=1, ipady=1)

label2.grid(row=0, column=1, padx=5, pady=5)

label3.grid(row=0, column=2, padx=1, pady=1)

label4.grid(row=1, column=0, ipadx=5, ipady=5)

label5.grid(row=1, column=1, padx=1, pady=1)

label6.grid(row=1, column=2, ipadx=5, ipady=5)

label7.grid(row=2, column=0, padx=1, pady=1)

label8.grid(row=2, column=1, ipadx=5, ipady=5)

label9.grid(row=2, column=2, padx=1, pady=1)

root.mainloop()

<h1 style="background:cyan;">标签按钮合作案例</h1>
单击按钮是从新设置标签上的显示内容

import tkinter as tk # 导入tkinter库

root = tk.Tk() # 建立程序主窗口

root.title("Button按钮的使用") # 设置主窗口的标题

root.geometry('600x500')

------功能函数

def f1():

var.set("单击按钮1")

def f2():

var.set("单击按钮2")

def f3():

var.set("单击按钮3")

------建立标签

labelx = tk.Label(root)

labelx.config(width=10, height=5)

labelx.config(activebackground='red')

labelx.config(activeforeground='yellow')

labelx.config(relief=tk.SUNKEN)

labelx.config(anchor=tk.CENTER)

定义字符串变量

var = tk.StringVar()

labelx.config(textvariable=var)

------建立第一个按钮

button1 = tk.Button(root, text='按钮1')

button1.config(width=5, height=2)

button1.config(activebackground='red')

button1.config(activeforeground='yellow')

button1.config(anchor=tk.CENTER)

button1.config(bd=2)

button1.config(relief=tk.RAISED)

button1.config(font=('隶书', -20))

button1.config(command=f1)

------建立第二个按钮

button2 = tk.Button(root, text='按钮2')

button2.config(width=5, height=2)

button2.config(activebackground='red')

button2.config(activeforeground='yellow')

button2.config(anchor=tk.CENTER)

button2.config(bd=2)

button2.config(relief=tk.RAISED)

button2.config(font=('隶书', -20))

button2.config(command=f2)

------建立第三个按钮

button3 = tk.Button(root, text='按钮3')

button3.config(width=5, height=2)

button3.config(activebackground='red')

button3.config(activeforeground='yellow')

button3.config(anchor=tk.CENTER)

button3.config(bd=2)

button3.config(relief=tk.RAISED)

button3.config(font=('隶书', -20))

button3.config(command=f3)

各个组件排兵布阵

labelx.grid(row=0, column=1)

button1.grid(row=1, column=0)

button2.grid(row=1, column=1)

button3.grid(row=1, column=2)

root.mainloop()

<h1 style="background:cyan;">标签案例</h1>
在主窗口中定义了三个标签

import tkinter as tk

root = tk.Tk()

label1 = tk.Label(root, text='标签1')

label1.config(fg='white', bg='black')

label2 = tk.Label(root, text='标签2')

label2.config(fg='red', bg='yellow')

label3 = tk.Label(root, text='标签3')

label3.config(fg='white', bg='green')

label1.grid(row=0, column=3)

label2.grid(row=1, column=2)

label3.grid(row=1, column=1)

root.mainloop()
