Python 当用户调整 window 大小时，tkinter 小部件的大小调整不均匀

Question

我正在为我的应用程序使用在 YouTube 视频中看到的模板。我使用 3 个帧将 window 分成 3 个。所有 3 个框架都嵌套在一个主框架中。主框架直接附在根window.

我正在使用包管理器将大型机放在根目录中 window。我正在使用网格管理器将 3 个框架放置在大型机中。

我面临的问题是，当我尝试调整 window 大小时，左框架比其他 2 框架调整得更多，我不明白为什么会这样。我需要框架彼此按比例调整大小。为什么左框架比其他框架调整得更多？我该如何纠正？

class MainApp(tk.Tk):

        tk.Tk.__init__(self, *args, **kwargs)

        mainframe = tk.Frame(self)
        mainframe.pack(side='top', fill='both', expand=True)
        mainframe.grid_rowconfigure(0, weight=1)
        mainframe.grid_columnconfigure(0, weight=1)
        #mainframe.grid(row=0, column=0, sticky='nesw')

        #left frame
        employerframe = tk.Frame(mainframe)
        employerframe.grid(row=0, column=0, sticky='nesw')
        employerframe.grid_rowconfigure(0, weight=1)
        employerframe.grid_columnconfigure(0, weight=1, uniform=1)
        label1 = tk.Label(employerframe, text='Employer Frame', font=Large_font)

        label2.grid(row=0, column=0, sticky='nesw')

        ttk.Separator(mainframe, orient=tk.VERTICAL) .grid(row=0, column=3, sticky='ns')

        #middle frame

        frame.tkraise()

class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)

Answer 1

这是因为您将employerframe、container、candidateframe放置到column=0、column=2、column=4。但是只给 weight=1 column=0。您还必须添加以下行以赋予列 0、2、4 相等的权重。

mainframe.grid_columnconfigure(2, weight=1)
mainframe.grid_columnconfigure(4, weight=1)

试试这个：

import tkinter as tk
from tkinter import ttk

Normal_Font = ('Verdana', 9)
Large_font = ('Verdana', 12)

class MainApp(tk.Tk):
    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

        mainframe = tk.Frame(self)
        mainframe.pack(side='top', fill='both', expand=True)
        mainframe.grid_rowconfigure(0, weight=1)
        mainframe.grid_columnconfigure(0, weight=1)
        # ----- Added lines -----
        mainframe.grid_columnconfigure(2, weight=1)
        mainframe.grid_columnconfigure(4, weight=1)

        #left frame
        employerframe = tk.Frame(mainframe)
        employerframe.grid(row=0, column=0, sticky='nesw')
        label1 = tk.Label(employerframe, text='Employer Frame', font=Large_font)
        label1.grid(row=0, column=0, sticky='nesw')

        ttk.Separator(mainframe, orient=tk.VERTICAL) .grid(row=0, column=1, sticky='ns')

        #right frame
        candidateframe = tk.Frame(mainframe)
        candidateframe.grid(row=0, column=4, sticky='nesw')
        label2 = tk.Label(candidateframe, text='Candidate Frame', font=Large_font)
        label2.grid(row=0, column=0, sticky='nesw')

        ttk.Separator(mainframe, orient=tk.VERTICAL) .grid(row=0, column=3, sticky='ns')

        #middle frame
        container = tk.Frame(mainframe)
        container.grid(row=0, column=2, sticky='nesw')

        self.frames = {}
        frame = StartPage(container, self)
        self.frames[StartPage] = frame
        frame.grid(row=0, column=0, sticky='nesw')
        self.show_frame(StartPage)

    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()

class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(self, text='Start Page', font=Large_font)
        label.pack(pady=10, padx=10)

app = MainApp()
app.mainloop()

Python tkinter widgets get resized uneven when user resizes the window
