我将展示给我带来问题的代码的缩减部分。
_tkinter.TclError: image "pyimageN" doesn't exist- 其中 N 停留 1、2、3 等......
第一类使用背景中的图像显示菜单。
class MenuWindow(): #in this class we show the main part of the program
def __init__(self):
self.Menu=Tk()
self.MCanvas=Canvas(self.Menu)
self.MCanvas.bind("<ButtonPress-1>",self.MenuClick)
#unuseful lines that configure the window and the canvas#
self.Background=PhotoImage(height=600,width=700)#a simple tkinter.PhotoImage object
#other unuseful lines that draw the photoimage ( without reading any file, with the method put())#
self.MCanvas.create_image((x,y),image=self.Background,state="normal")
#unuseful lines that continue the drawing of the canvas#
第二个类显示另一个窗口，在背景中使用另一个图像。该类由第一个类通过函数self.MenuClick的点击绑定启动。
class EditorWindow(): #in this class we show the main part of the program
def __init__(self):
self.Eenu=Tk()
self.ECanvas=Canvas(self.Eenu)
#unuseful lines that configure the window and the canvas#
self.Background=PhotoImage(height=600,width=700)
#other unuseful lines that draw the photoimage ( without reading any file , with the method put() )#
self.ECanvas.create_image((x,y),image=self.Background,state="normal")#in this line i get the error
#unuseful lines that continue the drawing of the canvas#
完整的回溯如下：
Exception in Tkinter callback
Traceback (most recent call last):

_tkinter.TclError: image "pyimage2" doesn't exist
这两个类的制作方式相似，所以我不知道为什么第二个类会出错。我确信这不是书写错误，例如（构造而不是构造）并且我使用的图像确实存在。
所以我认为：
我犯了一些概念错误，
或者它是 python 中的一个错误（或 Tkinter 的微妙行为）。
