由於 window 也在 tkinter GUI 中調整大小

Question

所以我做了這個簡單的程序。 問題是我事先沒有想到，當 window 調整大小時，我希望其中的所有對象也調整大小。 有沒有辦法寫一些簡單的東西來影響下面的一切，而不是寫一些東西到每一行？ 為了讓事情更清楚，您可以運行我的代碼並調整 window 的大小。 你會明白問題出在哪里：

from tkinter import * 
import sys
from PIL import ImageTk, Image
import math
import tkinter.font as TkFont

root = tk.Tk()


#Lango dydis
#root.geometry("500x600+0+0")
HEIGHT = 500
WIDTH = 600

canvas = tk.Canvas(root, height=HEIGHT, width=WIDTH )
canvas.pack()

frame=Frame(root, bg='#80c1ff', bd=5)
frame.place(relwidth=1, relheight=1)

trikampis = ImageTk.PhotoImage(Image.open("E:/Pytono projektai/240px-Rtriangle.png"))
trikampis2 = Label(root, image=trikampis)
trikampis2.place(relx= 0.29, rely= 0.2)


def skaiciuotuvas():
    error = Label(root, width=1, bg='#80c1ff', fg='#80c1ff')
    error.place(relwidth=0.8, relheight=0.04, relx= 0.12, rely= 0.905)
    a1 = ae.get()
    b1 = be.get()
    c1 = ce.get()
    if a1 == '':
        b11 = float(b1)
        c11 = float(c1)
        a11 = float(c11)**2 - float(b11)**2

我認為解決您的問題的唯一方法是將您使用的每個.place方法更改為.grid或.pack 。 在我看來，使用上述方法比使用place更簡單、更快捷。

Place 方法允許您設置相對或絕對 position，實際上您正在這樣做。 當你想讓你的小部件根據它的父級改變大小/位置時，它很有用。 如果這不是您的意圖，您應該使用grid或pack
