Python Treeview滚动条 [英] Python Treeview scrollbar

问题描述

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Treeview小部件.我尝试了多个版本，但无法使其正常工作.到目前为止，我已经尝试过:

My environment is Windows 7 using Python 64-bit 3.4. I am trying to attach a scrollbar to a treeview widget. I have tried several versions but have been unable to get it to work. What I have tried so far:

# 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()

推荐答案

您必须place()窗口中的滚动条.

You have to place() your scrollbar in window.

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pack()

But place() needs manual calculations of x and y. It is easier to use 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()

您总是可以将Treeview和Scrollbar放在Frame中，然后将place()，pack()或grid()移到更好的位置.

You can always put Treeview and Scrollbar in Frame and then move this frame with place(), pack() or grid() in better place.
