Python Treeview 滚动条

Question

我的环境是使用 Python 64 位 3.4 的 Windows 7。我正在尝试将滚动条附加到树视图小部件。我已经尝试了几个版本，但无法让它工作。到目前为止我尝试过的：

# treeview example
from tkinter import ttk
from tkinter import *

# Create instance
win = Tk()

# Add a title       
    win.title("Treeview Test")

# Add a treeview
    tree = ttk.Treeview(win,selectmode='browse')
    vsb = ttk.Scrollbar(orient="vertical",command=tree.yview)
    tree.configure(yscrollcommand=vsb.set)

    tree.place(x = 30, y = 95)
    tree["columns"] = ("1", "2")
    tree['show'] = 'headings'
    tree.column("1", width=100, anchor='c')
    tree.column("2", width=100, anchor='c')
    tree.heading("1", text="Account")
    tree.heading("2", text="Type")
    tree.insert("",'end',text="L1",values=("Big1","Best"))
    tree.insert("",'end',text="L2",values=("Big2","Best"))
    tree.insert("",'end',text="L3",values=("Big3","Best"))
    tree.insert("",'end',text="L4",values=("Big4","Best"))
    tree.insert("",'end',text="L5",values=("Big5","Best"))
    tree.insert("",'end',text="L6",values=("Big6","Best"))
    tree.insert("",'end',text="L7",values=("Big7","Best"))
    tree.insert("",'end',text="L8",values=("Big8","Best"))
    tree.insert("",'end',text="L9",values=("Big9","Best"))
    tree.insert("",'end',text="L10",values=("Big10","Best"))
    tree.insert("",'end',text="L11",values=("Big11","Best"))
    tree.insert("",'end',text="L12",values=("Big12","Best"))

# Set Window Form Size and disable resizing
    win.minsize(width=1200,height=600)
    win.resizable(width=0,height=0)  

# Event Loop
    win.mainloop()
    quit()

Answer 1

创建小部件后，您需要在 Tk 窗口上放置或布置小部件。 tkinter 中可用的布局管理器是 grid、pack 和 place。检查它们并将它们添加到您的小部件中。

Answer 2

你必须在窗口中place()你的滚动条。

from tkinter import ttk
import tkinter as tk

win = tk.Tk()
win.minsize(width=300, height=400)
win.resizable(width=0, height=0)

tree = ttk.Treeview(win, selectmode='browse')
tree.place(x=30, y=95)

vsb = ttk.Scrollbar(win, orient="vertical", command=tree.yview)
vsb.place(x=30+200+2, y=95, height=200+20)

tree.configure(yscrollcommand=vsb.set)

tree["columns"] = ("1", "2")
tree['show'] = 'headings'
tree.column("1", width=100, anchor='c')
tree.column("2", width=100, anchor='c')
tree.heading("1", text="Account")
tree.heading("2", text="Type")
tree.insert("",'end',text="L1",values=("Big1","Best"))
tree.insert("",'end',text="L2",values=("Big2","Best"))
tree.insert("",'end',text="L3",values=("Big3","Best"))
tree.insert("",'end',text="L4",values=("Big4","Best"))
tree.insert("",'end',text="L5",values=("Big5","Best"))
tree.insert("",'end',text="L6",values=("Big6","Best"))
tree.insert("",'end',text="L7",values=("Big7","Best"))
tree.insert("",'end',text="L8",values=("Big8","Best"))
tree.insert("",'end',text="L9",values=("Big9","Best"))
tree.insert("",'end',text="L10",values=("Big10","Best"))
tree.insert("",'end',text="L11",values=("Big11","Best"))
tree.insert("",'end',text="L12",values=("Big12","Best"))

win.mainloop()

但是place()需要手动计算x和y。使用更方便pack()

from tkinter import ttk
import tkinter as tk

win = tk.Tk()
win.resizable(width=0, height=0)

tree = ttk.Treeview(win, selectmode='browse')
tree.pack(side='left')

vsb = ttk.Scrollbar(win, orient="vertical", command=tree.yview)
vsb.pack(side='right', fill='y')

tree.configure(yscrollcommand=vsb.set)

tree["columns"] = ("1", "2")
tree['show'] = 'headings'
tree.column("1", width=100, anchor='c')
tree.column("2", width=100, anchor='c')
tree.heading("1", text="Account")
tree.heading("2", text="Type")
tree.insert("",'end',text="L1",values=("Big1","Best"))
tree.insert("",'end',text="L2",values=("Big2","Best"))
tree.insert("",'end',text="L3",values=("Big3","Best"))
tree.insert("",'end',text="L4",values=("Big4","Best"))
tree.insert("",'end',text="L5",values=("Big5","Best"))
tree.insert("",'end',text="L6",values=("Big6","Best"))
tree.insert("",'end',text="L7",values=("Big7","Best"))
tree.insert("",'end',text="L8",values=("Big8","Best"))
tree.insert("",'end',text="L9",values=("Big9","Best"))
tree.insert("",'end',text="L10",values=("Big10","Best"))
tree.insert("",'end',text="L11",values=("Big11","Best"))
tree.insert("",'end',text="L12",values=("Big12","Best"))

win.mainloop()

您始终可以将Treeview 和Scrollbar 放在Frame 中，然后将带有place()、pack() 或grid() 的框架移到更好的位置。

Answer 3

import tkinter as tk
from tkinter.ttk import Treeview, Scrollbar

top = tk.Tk()
top.geometry('1400x800')
top.configure(background="#f7f7f7")

# treeview initialization
treeview = Treeview(top)

# scrollbars
vsb = Scrollbar(top, orient="vertical", command=treeview.yview)
vsb.place(relx=0.978, rely=0.175, relheight=0.713, relwidth=0.020)

hsb = Scrollbar(top, orient="horizontal", command=treeview.xview)
hsb.place(relx=0.014, rely=0.875, relheight=0.020, relwidth=0.965)

treeview.configure(yscrollcommand=vsb.set, xscrollcommand=hsb.set)

也许这对你有帮助。
