Tkinter 重塑 canvas 不适用于面向对象

Question

我对 Tkinter 还是个新手，我正在尝试制作一个登录屏幕。功能在那里，但我希望我的 canvas 为 200x300px，但这似乎不起作用。它 returns 我用 canvas 刚好适合按钮和输入字段。请帮忙！

import tkinter as tk

class Login_Screen:
def __init__(self, master):
    self.master = master
    self.canvas = tk.Canvas(self.master, width=200, height=300)
    self.frame = tk.Frame(self.canvas)
    self.input_user_log = tk.Entry(self.frame)
    self.button1 = tk.Button(self.frame, text="Log in", width=15, command=self.return_login_info)
    self.input_user_log.pack()
    self.canvas.pack()
    self.button1.pack()
    self.frame.pack()

def return_login_info(self):
    print(self.input_user_log.get())


root = tk.Tk()
app = Login_Screen(root)
root.mainloop()

在 master 上使用 geometry() 方法。


import tkinter as tk

class Login_Screen:
    def __init__(self, master):
        self.master = master
        self.master.geometry("300x200")
        self.canvas = tk.Canvas(self.master)
        self.frame = tk.Frame(self.canvas)
        self.input_user_log = tk.Entry(self.frame)
        self.button1 = tk.Button(self.frame, text="Log in", width=15, command=self.return_login_info)
        self.input_user_log.pack()
        self.canvas.pack()
        self.button1.pack()
        self.frame.pack()
