如何对tkinter的"scrolledtext"进行编码.模块 [英] How to code the tkinter "scrolledtext" module

问题描述

下面的代码产生了一个丑陋但实用的示例，该示例在文本小部件中使用滚动条，并引发了几个问题.注意:这是在Windows框上使用Python 3完成的.

The code below produces an ugly but functional example of using a scroll bar in a text widget and results in a couple of questions. Note: this is done using Python 3 on a windows box.

1. 出现的滚动条被附加到框架上，尽管它滚动了文本框的内容，但我更希望它被附加到文本小部件本身.我一直无法做到这一点.

1. The scroll bar that appears is attached to the frame and although it scrolls the text box contents, I would prefer that it was attached to the text widget itself. I have been unable to get this to happen.

Tkinter模块有许多引用，称为"scrolledtext"，应该是将滚动条添加到文本框中的一种更好的机制，但是，我还没有找到任何有关如何导入和调用它的示例.我能够上班(可能需要一个例子).

There are a number of references to a Tkinter module called "scrolledtext" that is supposed to be a much better mechanism for adding scrollbars to text boxes but, I have not found any examples of how to import it and call it that I am able to get to work (probably need an example).

---

frame1 = tk.Frame(win,width=80, height=80,bg = '#808000')
frame1.pack(fill='both', expand='yes')
scrollbar = Scrollbar(frame1) 
scrollbar.pack(side=RIGHT, fill=Y)
editArea = Text(frame1, width=10, height=10, wrap=WORD, yscrollcommand=scrollbar.set)
editArea.pack()    
scrollbar.config(command=editArea.yview)
editArea.place(x=10,y=30)

推荐答案

您是对的，您可以使用tkinter.scrolledtext模块中的ScrolledText小部件，如下所示:

You were right, you can use the ScrolledText widget from tkinter.scrolledtext module, like this:

import tkinter as tk
import tkinter.scrolledtext as tkst

win = tk.Tk()
frame1 = tk.Frame(
    master = win,
    bg = '#808000'
)
frame1.pack(fill='both', expand='yes')
editArea = tkst.ScrolledText(
    master = frame1,
    wrap   = tk.WORD,
    width  = 20,
    height = 10
)
# Don't use widget.place(), use pack or grid instead, since
# They behave better on scaling the window -- and you don't
# have to calculate it manually!
editArea.pack(padx=10, pady=10, fill=tk.BOTH, expand=True)
# Adding some text, to see if scroll is working as we expect it
editArea.insert(tk.INSERT,
"""\

win.mainloop()
