乌龟与 Tkinter 发生冲突

Question

我要归档：一个叫curve，一个叫main。主要是我试图打开一个按钮 window，然后每当按下按钮时。它开始使用 turtle 绘制曲线。这是简化的脚本：

主要内容：

 import tkinter

    master = tkinter.Toplevel()

    def callback():
        print("click!")
        master.withdraw()
        b.quit()
        import curve

    b = tkinter.Button(master, text="OK", command=callback)
    b.pack()
    tkinter.mainloop()

曲线：

  import turtle

  turtle.bgpic("somefile.gif")
  #do some other stuff

然而当我运行这个我得到这个错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python34\lib\tkinter\__init__.py", line 1482, in __call__
    return self.func(*args)
  File "C:/Users/MYNAME/PycharmProjects/hilbert/main.py", line 7, in callback
    import curve
  File "C:\Users\MYNAME\PycharmProjects\hilbert\curve.py", line 3, in <module>
    turtle.bgpic("images/processed.gif")
  File "<string>", line 1, in bgpic
  File "C:\Python34\lib\turtle.py", line 1474, in bgpic
    self._setbgpic(self._bgpic, self._bgpics[picname])
  File "C:\Python34\lib\turtle.py", line 737, in _setbgpic
    self.cv.itemconfig(item, image=image)
  File "<string>", line 1, in itemconfig
  File "C:\Python34\lib\tkinter\__init__.py", line 2380, in itemconfigure
    return self._configure(('itemconfigure', tagOrId), cnf, kw)
  File "C:\Python34\lib\tkinter\__init__.py", line 1261, in _configure
    self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: image "pyimage2" doesn't exist

由于 turtle 是使用 tkinter 实现的，所以当您将两者混合时，您就像在走钢丝。您的代码返工似乎符合您的描述，包括 bgpic() 调用：

main.py

import tkinter
import turtle

turtle.Screen()
root = tkinter.Toplevel()

def callback():
    print("click!")
    root.withdraw()
    b.quit()
    import curve

b = tkinter.Button(root, text="OK", command=callback)
b.pack()

tkinter.mainloop()

curve.py

import turtle

turtle.bgpic('somefile.gif')

# do some other stuff

turtle.circle(100)

turtle.mainloop()
