无法在Tkinter画布中显示我的turtle对象

Question

我对Python很陌生。我想在Tkinter的画布上展示一个海龟的物体。我不知道为什么这个物体没有显示出来

为了使用Tkinter画布作为屏幕，我使用了RawTurtle()

root =tk.Tk()

outercanvas = Canvas(root, width=900, height=800, bg='#00ffff')
outercanvas.pack(expand=Y,fill=BOTH)

innercanvas = Canvas(outercanvas, width=680, height=700)
outercanvas.create_window(100, 40, anchor=NW, window=innercanvas)


bg = tk.PhotoImage(file="level2.png")
innercanvas.create_image(-5, 0, image = bg, anchor=NW)



bob = turtle.RawTurtle(innercanvas)

我希望乌龟出现在画布上，以便我以后可以操纵它。

我错过了什么

Answer 1

你的背景图片和乌龟似乎有冲突。试着这样做：

import tkinter as tk
from turtle import RawTurtle, TurtleScreen

root = tk.Tk()

outercanvas = tk.Canvas(root, width=900, height=800, bg='#00ffff')
outercanvas.pack(expand=tk.Y, fill=tk.BOTH)

innercanvas = tk.Canvas(outercanvas, width=680, height=700)
outercanvas.create_window(100, 40, anchor=tk.NW, window=innercanvas)

screen = TurtleScreen(innercanvas)
screen.bgpic("level2.gif")

bob = RawTurtle(screen)

bob.circle(100)

screen.mainloop()

请注意，我必须制作并使用“level2.gif”才能工作，但您可能有一个新的底层tkinter和turtle，它接受PNG文件
