Question

我试图获得相当于底部的红色框（在我的真实程序中它是标签和复选框）以扩展到顶部绿色框的大小（这也是我真实程序中的复选框）。填充和扩展似乎都无法正常工作。我也不能改变宽度。我做错了什么？

try:
    from tkinter import *
except ImportError:
    from Tkinter import *

class Application(Frame):
    def __init__(self,master=None):
        root = Tk()
        Frame.__init__(self,master)

        topframe = Frame(self)
        botframe = Frame(self)

        Frame(topframe, background="green", width=300, height = 200).grid(row =0, column = 0)
        Frame(botframe, background="red", width=200, height = 200).grid(row =1, column = 0, sticky = E)

        topframe.pack(side = TOP)
        botframe.pack(side = BOTTOM, fill = BOTH, expand = True)

        self.pack(fill="both", expand=True)
        root.mainloop()
Application()

我修好了，看看你是否有类似的问题

try:
    from tkinter import *
except ImportError:
    from Tkinter import *

class Application(Frame):
    def __init__(self,master=None):
        root = Tk()
        Frame.__init__(self,master)

        topframe = Frame(root)
        botframe = Frame(root)

        topframe.grid(row =0, column = 0, sticky=N+E+W)
        botframe.grid(row =1, column = 0, sticky=S+E+W)

        topframe.columnconfigure(0, weight=1)
        botframe.columnconfigure(0, weight=1)

        Frame(topframe, background="green", width=300, height = 200).grid(row =0, column = 0, sticky=N+E+W)
        Frame(botframe, background="red", width=200, height = 200).grid(row =1, column = 0, sticky = S+E+W)

        root.mainloop()
Application()

当您使用网格时，一条经验法则是您应grid_rowconfigure和grid_columnconfigure为至少一行和一列提供非零权重。这将导致该行和该列在布局中“占用空间”。

在tkinter中扩展多个帧
