当我尝试更换稻田时，为什么我的 Tkinter 按钮消失了？

Question

I tried to center the Button and set it to the Bottom but when i set the pady to 300, the Button disappear. So here my Question: Why does that happen and how do i fix it?

Here my Code:

import tkinter as tk


root = tk.Tk()
root.title("Test")
root.minsize(1000, 600)
root.maxsize(1000, 600)
root.config(bg = "#524D4C")


frame = tk.LabelFrame(root, padx=20, pady=20)

rolls = tk.Button(frame, width=20, height=2)
sides = tk.Button(frame, width=20, height=2)


frame.pack(pady=300)
rolls.grid(row=0, column=0)
sides.grid(row=0, column=2)

root.mainloop()

Answer 1

Why does my Tkinter Button disappear when i try to change the pady?

It is because the padding applies to both the top and bottom of the frame. You've forced the window to be 600 pixels tall, and 300*2 is 600, so the widget must shrink down to a height of zero for it to fit.
