python - 如何禁用键盘输入到 Entry 小部件，禁用调整 tkinter 窗口的大小并隐藏控制台窗口？

Question

我正在使用 tkinter 制作一个计算器，我希望执行以下操作:

• Disable keyboard input for the Entry widget so that the user can only input through the buttons.
• Even after disabling keyboard input for the Entry widget, I wish to be able to change the background and foreground of the widget.
• I wish to hide the console window because it is totally useless in the use of this calculator.
• I don't want to let the user resize the root window. How do I disallow the resizing of the root window?

到目前为止，这是我的代码...

from tkinter import *

root = Tk()
root.title("Calculator")
root.config(background="black")
operator = ""
textVar = StringVar()
def valInput(number):
    global operator
    operator+=str(number)
    textVar.set(operator)

display = Entry(root, textvariable=textVar, font=("Arial", 14, "bold"), bg="lightblue", fg="black", justify="right")
display.grid(row=0, column=0, columnspan=4)
btn7 = Button(root, font=("Arial", 12, "bold"), bg="orange", fg="red", text="7", command= lambda : valInput(7))
btn7.grid(row=1, column=0)

"""
And more buttons...

"""
root.mainloop()

如您所见，我可以使用按钮输入 Entry 小部件，但稍后，在计算器完成后，如果用户输入像 abcd 这样的字符...它会导致问题并显示错误。如何禁止键盘输入以避免这些错误？

我想让我的计算器有点色彩。我更改了 root 窗口的颜色、按钮以及 Entry 小部件的颜色。即使在禁用后，是否有任何方法可以更改小部件的颜色？

我在使用这个计算器时不需要控制台窗口。我该如何隐藏它？

如果我调整 root 窗口的大小，计算器会变得丑陋，此外，不需要调整窗口的大小。那么如何防止用户调整窗口大小呢？
