在类中如何让第二个画布出现在 tkinter 顶级窗口上？

Question

我正在使用 Tkinter 创建一个应用程序，通过这个 Dashboard 类，我试图获取一个弹出窗口来显示另一个画布，因此我可以在弹出窗口上使用 create_image 和 tag_bind 。我当前得到的结果是第二个画布出现在第一个画布上，而不是出现在弹出窗口中。

import tkinter as tk
from tkinter import *

class Dashboard(tk.Tk):
    """
    Configures, and displays the Dashboard
    """

    def __init__(self):
        tk.Tk.__init__(self)
        self.config(width=1440, height=1024)

        canvas = tk.Canvas(self, bg="#343333", height=1024, width=1440, bd=0, highlightthickness=0, relief="ridge")
        canvas.place(x=0, y=0)

        # Captures the background image for the canvas
        image_path = "dashboard_background.png"
        self.background_img = tk.PhotoImage(file=image_path)
        canvas.create_image(0, 0, anchor='nw', image=self.background_img)

        def logoutbuttonClicker():
            pop = Toplevel(self)
            pop.geometry('537x273')
            pop.config(height=273, width=537)

            logout_canvas = tk.Canvas(canvas, bg="#ffffff", height=273, width=537, bd=0, highlightthickness=0, relief="ridge")
            logout_canvas.place(x=0, y=0)

            self.logout_background_img = PhotoImage(file=f"logout_background.png")
            logout_canvas.create_image(268.5, 136.5, anchor='nw', image=self.logout_background_img)
            
            self.logout_yes_img = PhotoImage(file=f"logout_yes.png")
            self.logout_no_img = PhotoImage(file=f"logout_no.png")

        logout_image_path = "dashboard_logout.png"
        self.logout_image = tk.PhotoImage(file=logout_image_path)
        logoutButton = canvas.create_image(45, 950, anchor='nw', image=self.logout_image)
        canvas.tag_bind(logoutButton, "<ButtonRelease-1>", lambda event: logoutbuttonClicker())

def main():
    app = Dashboard()
    app.mainloop()

if __name__ == '__main__':
    main()

这是它当前在 UI 中的显示方式
