问题描述
我将展示减少部分代码，这给我带来了麻烦.
I will show a reduced portion of the code that gives me a problem.
_tkinter.TclError: image "pyimageN" doesn't exist-其中N停留1、2、3等...
_tkinter.TclError: image "pyimageN" doesn't exist - where N stays for 1, 2, 3, etc...
第一类使用背景图像显示菜单.
There is a first class that shows a menu using an image in the background.
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#
第二类显示另一个窗口，在后台使用另一个图像.此类由第一类通过函数self.MenuClick的单击绑定启动.
And a second class that shows another window, using another image in the background. This class is launched by the first class via click binding of the function self.MenuClick.
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):
File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/tkinter/__init__.py", line 1399, in __call__
return self.func(*args)
File "/Users/albertoperrella/Desktop/slay.py", line 70, in MenuClick
EditorWindow(self)
File "/Users/albertoperrella/Desktop/slay.py", line 85, in __init__
self.ECanvas.create_image((3,3),image=self.Background,state="normal",anchor="nw")
File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/tkinter/__init__.py", line 2140, in create_image
return self._create('image', args, kw)
File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/tkinter/__init__.py", line 2131, in _create
*(args + self._options(cnf, kw))))
_tkinter.TclError: image "pyimage2" doesn't exist
这两个类的制作方法相似，所以我不知道为什么第二个类会出错.我确定这不是写错误，例如(用conttruct代替construct)，并且我使用的图像确实存在.
The two classes are made in a similar way, so I don't know why I get the error with the second one. I am sure that it isn't a writing error e.g.(conttruct instead of construct) and that the images I am using actually exist.
所以我认为:
-
我在犯一些概念错误，
I am making some concept mistakes,
或者它是python中的错误(或Tkinter的细微行为).
or it is a bug (or subtle behaviour of Tkinter) in python.
推荐答案
我为自己解决了这个问题:
I solved myself the problem :
我定义的第二个类是问题，因为它使用了另一个根窗口，别名为Tk().与普通Tk()窗口等效的是Toplevel()，它与根相同，但没有自己的解释器上下文.
The second class I defined was the problem cause it used another root window, alias Tk(). An equivalent to the normal Tk() window is the Toplevel() that is the same as a root but hasn't its own interpreter context.
很快，要解决该问题，我不得不将EditorWindow类的 init ()方法的第一行更改为
Shortly, to solve the problem I had to change the first line of the init() method of the EditorWindow class from
self.Eenu=Tk()
到
self.Eenu=Toplevel()
