Python TKinter：当窗口被调整大小时，框架和画布会水平扩展，但不是垂直扩展

Question

由于某些原因，我能够在调整窗口大小时获得此TKinter帧（allValOuterFrame）以垂直和水平方向展开，但是看起来，该框架所持有的画布以及该画布内的框架和垂直滚动条只会水平展开。有人能解释为什么吗？

这里是我的代码：

# 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

from extractor import Analysis 
from extractor import createDictionariesAndLists as getRawData 
from nitrogenCorrector import correct as nCorrect 
from carbonCorrector import correct as cCorrect

Answer 1

那是因为你给的AllValOuterFrame 0行1的权重，但你把帆布行1.如果你将画布0行或放弃行1的权重为1，它会调整你期望的方式。
