如何使用 tkinter 向窗口添加滚动条? [英] How to add a scrollbar to a window with tkinter?

问题描述

我有一个 tkinter 程序:

I have a tkinter program:

import urllib.request
from tkinter import *


root = Tk()
root.iconbitmap(default='icon.ico')
root.wm_title('Got Skills\' Skill Tracker')
frame = Frame(width="500",height="500")
frame.pack()


def show():
  name = "zezima"
  page = urllib.request.urlopen('http://hiscore.runescape.com/index_lite.ws?player=' + name)
  page = page.readlines()

  skills = []
  for line in page:
    skills.append([line.decode("utf-8").replace("\n", "").split(",")])

  skills = skills[0:25]

  for item in skills:
    toPrint = item[0][0],"-",item[0][1],"-",item[0][1],"\n"
    w = Message(frame, text=toPrint)
    w.pack()


menu = Menu(root)
root.config(menu=menu)

filemenu = Menu(menu)
menu.add_cascade(label="Commands", menu=filemenu)
filemenu.add_command(label="Show Skills", command=show)


root.mainloop()

当我运行上面的脚本时，它显示了这一点(这很好):

When I run the above script, it shows this (which is good):

当我点击命令 > 显示技能时，它变成了this.(链接是因为它很高.)它显示了正确的东西，但是......我可以想象你看到了问题.

When I click Commands > Show Skills, it turns into this. (Linked because it's tall.) It shows the right thing, but...I can imagine you see the problem.

两个问题:

-如何向框架添加滚动条，并保持框架的固定大小?(理想情况下，保持第一张图片的大小，添加 show() 的输出，在程序的第一张图片上添加滚动条.)- 使用以下代码:

-How do I add a scrollbar to the frame, and keep the frame a fixed size? (Ideally, keep the size of the first image, add the output of show(), add a scrollbar to the first image of the program.) -With the following code:

  for item in skills:
    toPrint = item[0][0],"-",item[0][1],"-",item[0][2],"\n"
    w = Message(frame, text=toPrint)
    w.pack()

这是输出我输出内容的最佳方式吗?列表(skills)看起来像[[1,2,3],[4,5,6]..]，我想显示1-2-一行 3 个，一行 4 - 5 - 6 个，等等.

Is that the best way to output what I'm outputting? The list (skills) looks like [[1,2,3],[4,5,6]..], and I want to display 1-2-3 on a line, 4 - 5 - 6 on a line, etc.

但是，我不希望像现在这样在它们之间出现额外的界线，我想知道我是如何做到的是否是最好的方法.

But, I don't want that extra line in between them like there is now, and I was wondering if how I did it is the best way to go about doing it.

推荐答案

要添加滚动条，请使用 tkinter.tix.ScrolledWindow.

To add the scroll bars, use tkinter.tix.ScrolledWindow.

要删除多余的空间，请删除多余的\n"并显示字符串，而不是元组.完整代码如下:

To remove extra space drop the extra "\n" and display a string, not a tuple. Here is the complete code:

import urllib.request
from tkinter import *
from tkinter.tix import *

root = Tk()
root.iconbitmap(default='icon.ico')
root.wm_title('Got Skills\' Skill Tracker')
frame = Frame(width="500",height="500")
frame.pack()
swin = ScrolledWindow(frame, width=500, height=500)
swin.pack()
win = swin.window


def show():
  name = "zezima"
  page = urllib.request.urlopen('http://hiscore.runescape.com/index_lite.ws?player=' + name)
  page = page.readlines()

  skills = []
  for line in page:
    skills.append([line.decode("utf-8").replace("\n", "").split(",")])

  skills = skills[0:25]

  for item in skills:
    toPrint = item[0][0],"-",item[0][1],"-",item[0][1]
    w = Message(win, text=' '.join(toPrint), width=500)
    w.pack()


menu = Menu(root)
root.config(menu=menu)

filemenu = Menu(menu)
menu.add_cascade(label="Commands", menu=filemenu)
filemenu.add_command(label="Show Skills", command=show)


root.mainloop()
