Making an extremely simple program where a button follows the mouse, and when clicked, should randomly resize. But I when I run the code below, I get an error, saying that the “height” property is unknown.
Code:

import tkinter as tk
from tkinter import ttk
import random

window = tk.Tk()

def moved(e):
    myx = e.x
    myy = e.y
    mylbl.place(x=myx - 20, y=myy - 20)

def randomsize():
    size = random.randrange(20, 200)
    sizey = size * 2
    mylbl.config(width= sizey, height = size)

mylbl = ttk.Button(window, text="Hello", command=randomsize, height=30, width = 60)
mylbl.place(x=10, y=10)
window.bind("<Motion>", moved)

window.mainloop()

Error:

in _configure
    self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: unknown option "-height"
