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()
