Question

我需要有关此程序的帮助，此程序应该通过单击按钮在新的tkinter窗口中打开图像，但它不会只打开没有图像的新窗口。问题在哪里？

使用：python 3.3和tkinter

这是程序：

import sys
from tkinter import *


def button1():
    novi = Toplevel()
    canvas = Canvas(novi, width = 300, height = 200)
    canvas.pack(expand = YES, fill = BOTH)
    gif1 = PhotoImage(file = 'image.gif')
    canvas.create_image(50, 10, visual = gif1, anchor = NW)


mGui = Tk()
button1 = Button(mGui,text ='Sklop',command = button1, height=5, width=20).pack()

mGui.mainloop()

Answer 1

create_image需要image参数，而不是visual才能使用该图片，因此您需要visual = gif1而非image = gif1，而不是gif1。下一个问题是你需要在某处存储import sys from tkinter import * #or Tkinter if you're on Python2.7 def button1(): novi = Toplevel() canvas = Canvas(novi, width = 300, height = 200) canvas.pack(expand = YES, fill = BOTH) gif1 = PhotoImage(file = 'image.gif') #image not visual canvas.create_image(50, 10, image = gif1, anchor = NW) #assigned the gif1 to the canvas object canvas.gif1 = gif1 mGui = Tk() button1 = Button(mGui,text ='Sklop',command = button1, height=5, width=20).pack() mGui.mainloop()引用，否则它将被垃圾收集，tkinter将无法再使用它。

这样的事情：

Button

将button1命名为与函数{{1}}相同的名称也可能不是一个好主意，这只会在以后造成混淆。

Answer 2

from tkinter import *
root = Tk()
root.title("Creater window")

def Img():
    r = Toplevel()
    r.title("My image")

    canvas = Canvas(r, height=600, width=600)
    canvas.pack()
    my_image = PhotoImage(file='C:\\Python34\\Lib\idlelib\\Icons\\Baba.gif', master= root)
    canvas.create_image(0, 0, anchor=NW, image=my_image)
    r.mainloop()

btn = Button(root, text = "Click Here to see creator Image", command = Img)
btn.grid(row = 0, column = 0)

root.mainloop()

单击按钮，在tkinter窗口中显示图像
