Python 3.x 试图添加一个功能类似于按钮的图像,但出现此错误,image";pyimage2“;不';不存在,弹出窗口
我已经有了一套与下面的格式类似的代码,而且似乎可以工作。但不知何故,这张照片的图像并没有出现。它们和代码在同一个文件夹中。Def small是使图像工作的代码,而Def stripes是给我一个错误的代码Python 3.x 试图添加一个功能类似于按钮的图像,但出现此错误,image";pyimage2“;不';不存在,弹出窗口,python-3.x,tkinter,tkinter-canvas,ttk,Python 3.x,Tkinter,Tkinter Canvas,Ttk,我已经有了一套与下面的格式类似的代码,而且似乎可以工作。但不知何故,这张照片的图像并没有出现。它们和代码在同一个文件夹中。Def small是使图像工作的代码,而Def stripes是给我一个错误的代码 from tkinter import * import tkinter as tk from tkinter import ttk def small(): s = Tk() s.title('Small Preset Shirt (Not fit to scale)')

以下是完整的回溯:
Exception in Tkinter callback

_tkinter.TclError: image "pyimage2" doesn't exist
当您收到错误消息“
\u tkinter.TclError:image“pyimage2”不存在
”或类似信息时,表示tkinter无法确定它是哪个窗口的照片。这是由于存在多个Tk()
windows。当您使用多个Tk
时,几乎没有其他东西会造成问题,这就是为什么Tkinter有另一种类型的窗口Toplevel
,它像子窗口一样引用主窗口
让我们进入您的代码。
在这里,除了这个错误,我看到了一些其他的问题
Tk()
窗口。我相信你可能有两个以上mainloop()
一个窗口足以打开尽可能多的Toplevel窗口,但请记住在代码末尾至少使用一个mainloop()
Photoimage
时,python会清除该图像,即使该图像是通过标签
或画布
显示的。因此,在这种情况下,请始终创建一个引用from tkinter import *
from tkinter import ttk
Main_window = Tk() # Make only one Tk main window
Main_window.geometry('300x150')
Main_window.title("Get Shirts (Buy 1 get 1 Free)")
def small():
s = Toplevel() # For secondary window use Toplevel
s.title('Small Preset Shirt (Not fit to scale)')
canvas = Canvas(s, width = 800, height = 100)
canvas.pack()
b1=ttk.Button(s,text='Click to Start', command = None)
b1.pack()
photo = PhotoImage(file = 'logo.png')
b1.img_ref = photo # Create a reference
b1.config(image=photo,compound=RIGHT)
# s.mainloop() # Don't use mainloop more than once

b2.img_ref = photo # Sometimes images in functions becomes garbage value.

你是如何调用这两个函数的?您是否使用线程同时执行这两个函数?
