Question

我有一个tkinter程序：

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，它显示了这个（这很好）：

alt text http://img708.imageshack.us/img708/8821/tkinter1.png

当我点击命令＆gt;显示技能，它变成this。（链接因为它很高。）它显示正确的东西，但是......我可以想象你看到了问题。

两个问题：

- 如何向框架添加滚动条，并将框架保持固定尺寸？（理想情况下，保持第一个图像的大小，添加show（）的输出，将滚动条添加到程序的第一个图像。） - 使用以下代码：

  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]..]，我希望在一行上显示1-2-3，在一行上显示4 - 5 - 6等。

但是，我不希望它们之间有额外的线条，就像现在一样，我想知道我是怎么做的，这是最好的方法。

Answer 1

要添加滚动条，请使用tkinter.tix.ScrolledWindow。

要删除多余的空格，请删除额外的“\ n”并显示一个字符串，而不是元组。这是完整的代码：

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()

这是一个滚动框架的类。只需将 window 对象作为传统的 tkinter 样式传递，并使用 obj.frame 作为新小部件的窗口。

class ScrollableFrame:
    """
    # How to use class
    from tkinter import *
    obj = ScrollableFrame(master,height=300 # Total required height of canvas,width=400 # Total width of master)
    objframe = obj.frame
    # use objframe as the main window to make widget
    """
    def __init__ (self,master,width,height,mousescroll=0):
        self.mousescroll = mousescroll
        self.master = master
        self.height = height
        self.width = width
        self.main_frame = Frame(self.master)
        self.main_frame.pack(fill=BOTH,expand=1)

        self.scrollbar = Scrollbar(self.main_frame, orient=VERTICAL)
        self.scrollbar.pack(side=RIGHT,fill=Y)

        self.canvas = Canvas(self.main_frame,yscrollcommand=self.scrollbar.set)
        self.canvas.pack(expand=True,fill=BOTH)

        self.scrollbar.config(command=self.canvas.yview)

        self.canvas.bind('<Configure>', lambda e: self.canvas.configure(scrollregion = self.canvas.bbox("all")))

        self.frame = Frame(self.canvas,width=self.width,height=self.height)
        self.frame.pack(expand=True,fill=BOTH)
        self.canvas.create_window((0,0), window=self.frame, anchor="nw")

        self.frame.bind("<Enter>", self.entered)
        self.frame.bind("<Leave>", self.left)

    def _on_mouse_wheel(self,event):
        self.canvas.yview_scroll(-1 * int((event.delta / 120)), "units")

    def entered(self,event):
        if self.mousescroll:
            self.canvas.bind_all("<MouseWheel>", self._on_mouse_wheel)
        
    def left(self,event):
        if self.mousescroll:
            self.canvas.unbind_all("<MouseWheel>")

如何使用tkinter将滚动条添加到窗口？
