Tkinter是内置的标准python库。借助Tkinter, 可以轻松创建许多GUI应用程序。 Tkinter中有各种类型的小部件可用, 例如按钮, 框架, 标签, 菜单, scrolledtext, 画布等等。小部件是提供各种控件的元素。 ScrolledText小部件是带有滚动条的文本小部件。 tk滚动文本模块提供文本小部件以及滚动条。此小部件可帮助用户方便地输入多行文本。除了向文本小部件中添加滚动条, 我们还可以使用帮助输入任意行文本的scrolledtext小部件。

示例1：显示scrolledText小部件的Python代码。

# Python program demonstrating
# ScrolledText widget in tkinter
import tkinter as tk
from tkinter import ttk
from tkinter import scrolledtext
# Creating tkinter main window
win = tk.Tk()
win.title( "ScrolledText Widget" )
# Title Label
ttk.Label(win, text = "ScrolledText Widget Example" , font = ( "Times New Roman" , 15 ), background = 'green' , foreground = "white" ).grid(column = 0 , row = 0 )
# Creating scrolled text 
# area widget
text_area = scrolledtext.ScrolledText(win, wrap = tk.WORD, width = 40 , height = 10 , font = ( "Times New Roman" , 15 ))
text_area.grid(column = 0 , pady = 10 , padx = 10 )
# Placing cursor in the text area
text_area.focus()win.mainloop()

输出：

示例2：ScrolledText小部件, 使tkinter文本为只读。

# Importing required modules
import tkinter as tk
import tkinter.scrolledtext as st
# Creating tkinter window
win = tk.Tk()
win.title( "ScrolledText Widget" )
# Title Label
tk.Label(win, text = "ScrolledText Widget Example" , font = ( "Times New Roman" , 15 ), background = 'green' , foreground = "white" ).grid(column = 0 , row = 0 )
# Creating scrolled text area
# widget with Read only by
# disabling the state
text_area = st.ScrolledText(win, width = 30 , height = 8 , font = ( "Times New Roman" , 15 ))
text_area.grid(column = 0 , pady = 10 , padx = 10 )
# Inserting Text which is read only
text_area.insert(tk.INSERT, """\
This is a scrolledtext widget to make tkinter text read only.
Hi

# Making the text read only
text_area.configure(state = 'disabled' )win.mainloop()
