[英]Tkinter scrollbar not scrollable
I followed some tutorial on attaching a scrollbar to a textbox.我遵循了一些关于将滚动条附加到文本框的教程。 However, in the tutorial, the scrollbar is really a "bar".但是,在教程中,滚动条实际上是一个“条”。 When I tried myself, I can only press the arrows to move up or down, the middle part is not movable.自己试了一下,只能按箭头上下移动,中间部分不可动。 May I know what I did wrong?我可以知道我做错了什么吗?
import tkinter as tk
root = tk.Tk()
scroll = tk.Scrollbar(root)
scroll.grid(row = 0, column = 1)
message = tk.Text(root, yscrollcommand = scroll.set, height = 25, width = 60)
message.grid(row = 0, column = 0)
for i in range(50):
message.insert(tk.END, f'This is line {i}\n')
scroll.config(command = message.yview)
root.mainloop()
You just have to add sticky='nsew'
to Scrollbar
widget.您只需将sticky='nsew'
添加到Scrollbar
小部件。
sticky='nsew'
will make the Scrollbar
widget to expand to fill up the entire cell (at grid position row=0
& column=1
) at every side (n- north , s- south , e- east , w- west ) sticky='nsew'
将使Scrollbar
小部件在每一侧(n-北,s-南,e-东,w-西)扩展以填满整个单元格(在网格位置row=0
& column=1
)
Here is the code:这是代码:
import tkinter as tk
root = tk.Tk()
scroll = tk.Scrollbar(root)
# add sticky option to the Scrollbar widget
scroll.grid(row = 0, column = 1, sticky='nsew')
message = tk.Text(root, yscrollcommand = scroll.set, height = 25, width = 60)
message.grid(row = 0, column = 0)
for i in range(50):
message.insert(tk.END, f'This is line {i}\n')
scroll.config(command = message.yview)
root.mainloop()
