Question

出于某种原因，我可以让这个TKinter框架（allValOuterFrame）在调整窗口大小时垂直和水平扩展，但是，看起来框架所拥有的画布，以及该画布内的框架和垂直滚动条只会水平扩展。有人可以解释一下原因吗？

这是我的代码：

# At first I only had "from X import *" but then discovered that
# it is bad practice, so I also included "import X" statements so
# that if I need to use something from tk or ttk explicitly, I can,
# but I had 2/3 of my code done at that point so I had to leave in the
# "import *" things.
try:
    from Tkinter import * #python 2
    import Tkinter as tk
    from ttk import *
    import ttk
    import tkMessageBox as msg
    import tkFileDialog as openfile
except ImportError:
    from tkinter import * #python 3
    import tkinter as tk
    from tkinter.ttk import *
    import tkinter.ttk as ttk
    from tkinter import messagebox as msg
    from tkinter import filedialog as openfile
import csv
# My stuff:
from extractor import Analysis
from extractor import createDictionariesAndLists as getRawData
from nitrogenCorrector import correct as nCorrect
from carbonCorrector import correct as cCorrect

def createAllValWindow(self):

    allValWindow = Toplevel(self)
    allValWindow.grab_set()

    if self.element == "N":
        allValWindow.title("All Nitrogen Raw Data Values")
    elif self.element == "C":
        allValWindow.title("All Carbon Raw Data Values")
    else:
        allValWindow.title("All Raw Data Values")

    allValOuterFrame = tk.Frame(allValWindow,background="#00FF00")
    allValCanvas = Canvas(allValOuterFrame, borderwidth=0)

    def allValOnFrameConfigure(event):

    allValInnerFrame.bind("<Configure>",allValOnFrameConfigure)
    allValDoneButton = Button(allValWindow,text="Done",command=allValWindow.destroy)
    allValOuterFrame.pack(fill="both",expand=1)
    allValDoneButton.pack()

    textRows = [self.rawHeader]
    textLabels = [[]]
    numDiffAminos = len(self.analyses) - 1 # Ignore the "trash" list at the end
    for singleAminoAnalyses in self.analyses[0:numDiffAminos]: # Once again, ignoring the last list
        if len(singleAminoAnalyses) < 1:
            continue
        for analysis in singleAminoAnalyses:
            textRows.append([str(analysis.analysisID),

            else:
                textLabels[i].append(Label(allValInnerFrame,text=textRows[i][j]))
            if j == 9:
                textLabels[i][j].grid(row=listRow,column=j,sticky=W+E,padx=(4,10))
            else:
                textLabels[i][j].grid(row=listRow,column=j,sticky=W+E,padx=(4,4))
        if i == 0:
            separator = tk.Frame(allValInnerFrame, height=2, borderwidth=1, bg="black", relief=SUNKEN)
            separator.grid(row=1,column=0,columnspan=12,sticky=W+E)

Answer 1

这是因为你给AllValOuterFrame的第0行权重为1，但你将画布放在第1行。如果你将画布移动到第0行或给第1行增加1的权重，它会调整大小你期望的方式。

Python TKinter：当调整窗口大小时，框架和画布将水平扩展，但不会垂直扩展
