我正在尝试使用Tkinter制作UI，但在将三个Scrollbars放入LabelFrames时遇到问题。
我有一个名为self.que_lt_ver的数组，其中包含一些名称：self.que_lt_ver = ['CARGA', 'MAQUINA', SOLTAR']。我想创建3个LabelFrame，每个均带有Scrollbar。我为它创建了一个Canvas，但是它仅显示最后一个窗口的Scroll：
那么，如何修改代码以显示每个LabelFrame的滚动？
这是创建窗口的代码部分：
def createBox(self, window):
for i in xrange(len(self.que_lt_ver)):
mybox = LabelFrame(window, padx=5, pady=4)
mybox.grid(row=i, column=0)
self.createWindow(mybox, self.que_lt_ver[i], i)
def createWindow(self, box, lt_actual, i):
self.canvas = Canvas(box, borderwidth=0)
frame = Frame(self.canvas)
vsb = Scrollbar(box, orient="vertical", command=self.canvas.yview)
self.canvas.configure(yscrollcommand=vsb.set, width=1200, heigh=80)
vsb.pack(side="right", fill="y")
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas.create_window((4,4), window=frame, anchor="nw", tags="frame")
frame.bind("<Configure>", self.OnFrameConfigure)
self.fillWindow(lt_actual, frame)
def fillWindow(self, lt_ver, frame):

提前致谢。
最佳答案
您创建了3个画布，但是所有画布都设置在self.canvas中。
因此self.canvas对应于最后一个。您配置了3次，但从未两次配置。
查看我的解决方案（我删除了所有对象的东西）：
from Tkinter import *
def createBox(window):
list_ = ['CARGA', 'MAQUINA', 'SOLTAR']
for i in xrange(3):
mybox = LabelFrame(window, padx=5, pady=4)
mybox.grid(row=i, column=0)
createWindow(mybox, list_[i], i)
def createWindow(box, lt_actual, i):
canvas = Canvas(box, borderwidth=0)
frame = Frame(canvas)
vsb = Scrollbar(box, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=vsb.set, width=1200, heigh=80)
vsb.pack(side="right", fill="y")
canvas.pack(side="left", fill="both", expand=True)
canvas.create_window((4,4), window=frame, anchor="nw", tags="frame")
# be sure that we call OnFrameConfigure on the right canvas
frame.bind("<Configure>", lambda event, canvas=canvas: OnFrameConfigure(canvas))
fillWindow(lt_actual, frame)
def fillWindow(lt_ver, frame):
piezas = ['time: 39.41597 BT: 3025.5923', 'time: 21.637377 BT: 3025.5923', 'time: 52.185192 BT: 3025.5923', 'time: 57.804752 BT: 3025.5923', 'time: 47.700306 BT: 3025.5923', 'time: 21.1827 BT: 3025.5923', 'time: 35.244156 BT: 3025.5923', 'time: 47.26321 BT: 3025.5923']
