Question

所以我在这里搜索过的线程尝试了很多不同的解决方案。这是我的代码：

def begin():

    global path, thumbPath, fullImgPath, running
    root = Tkinter.Tk()
    root.title("keyBuilder")

    frame = Frame(root, width = 630, height = 450)
    frame.pack()

    exitButton = Button(frame, text="Exit keyBuilder", width=10, command=exitProgram)
    exitButton.grid(row = 0, column = 0)

    Running = True
    b = Button(frame, text="Set Directory Path", width=20, command=getPath)
    b.grid(row = 0, column = 1)

    groupMenu = Frame(frame, width = 150)
    tree = Treeview(groupMenu, selectmode = 'browse')
    tree.pack(fill = Y)
    tree.insert(parent = '', index = 'end', text = 'Master')
    a = tree.insert(parent = '', index = 'end', text = 'Group 1')
    tree.insert(parent = a, index = 'end', text = 'Slide 1')

    yscrollbar = Tkinter.Scrollbar(frame, orient = VERTICAL)
    numImages = 0
    for infile in glob.glob(os.path.join(path + '/imgThumb/', '*jpg')):
        numImages += 1
    COLUMNS = 4
    image_count = 0

    gallery = Canvas(frame, width = COLUMNS * THUMB_SIZE, height = COLUMNS * THUMB_SIZE, yscrollcommand = yscrollbar.set)#
    yscrollbar.config(command = gallery.yview)
    for infile in glob.glob(os.path.join(path + '/imgThumb/', '*.jpg')):
        print "filling gallery with: " + infile
        image_count += 1
        r, c = divmod(image_count-1, COLUMNS)
        im = Image.open(infile)
        tkimage = ImageTk.PhotoImage(im)
        myvar = Label(gallery, image=tkimage)
        myvar.image = tkimage
        gallery.create_window(c*THUMB_SIZE, r*THUMB_SIZE, anchor = NW, window = myvar)
    gallery.config(scrollregion=gallery.bbox(ALL))
    yscrollbar.config(command = gallery.yview)
    groupMenu.grid(row = 1, column = 0)
    gallery.grid(row = 1, column = 1)
    yscrollbar.grid(row = 1, column = 2)
    yscrollbar.config(command = gallery.yview)
    root.mainloop()

以下是我使用的所有可能与此问题有关的软件包：

import pymongo
import glob, os
from subprocess import Popen
import Tkinter
from Tkinter import *
from ttk import *
from PIL import Image, ImageTk
import zipfile
import shutil

我尝试过设置滚动条和画布，并以许多不同的顺序填充画布。我试过给画布特定的滚动区域。我似乎无法让滚动条工作。

谢谢！

Answer 1

解决了它。我不得不添加

sticky = NE + SE

作为

的论据

yscrollbar.grid()

并将滚动条放在保持滚动滚动的列左侧的列中。

我认为滚动条始终存在，但网格几何管理器将其放置在我无法访问的位置。

Tkinter滚动条没有显示
