Question

我对tkinter很新，我注意到当我尝试将一张图片作为背景添加到我的窗口时，它只是不会显示出来。这是代码。

from tkinter import *

root = Tk()

def cheese():
    root.destroy()

logo = PhotoImage('../Desktop/logothing.gif')
background_label = Label(root, image=logo)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

explanation = """Flaming Arrows whizz over your hair, War rages around you. Suddenly,
it charges into you. A 8 foot tall mechanical beast the enemy have been training for war.
You have no chance but to fight it. You swing your sword as hard as you can...Only to
leave a minor dent on it's armor. With one blow from its club, you fall unconscious."""

w = Label(root, image=logo).pack(side='right')
w1 = Button(root, text = 'Wake Up',command = cheese, fg='blue', font = "Impact 20")
w1.pack(side='bottom')

w2 = Label(root, 
           justify=LEFT, 
           text=explanation,
           compound = CENTER,
           fg="blue", padx=0,font="ComicSansMS 32 bold")
w2.pack(side='left')

Answer 1

您需要使用file指定该选项。 PhotoImage(file = "foo.gif")

另外，如PhotoImage's page on effbot所述，

您必须在Python程序中保留对图像对象的引用，通过将其存储在全局变量中，或通过将其附加到另一个对象。

from tkinter import *

root = Tk()
def cheese():
    root.destroy()
logo = PhotoImage(file = '../Desktop/logothing.gif')
background_label = Label(root, image=logo)
background_label.image = logo
background_label.place(x=0, y=0, relwidth=1, relheight=1)
explanation = """Flaming Arrows whizz over your hair, War rages around you. Suddenly,
it charges into you. A 8 foot tall mechanical beast the enemy have been training for war.
You have no chance but to fight it. You swing your sword as hard as you can...Only to
leave a minor dent on it's armor. With one blow from its club, you fall unconscious."""
w= Label(root, image=logo).pack(side='right')
w1 = Button(root, text = 'Wake Up',command = cheese, fg='blue', font = "Impact 20")
w1.pack(side='bottom')

w2 = Label(root, 
           justify=LEFT, 
           text=explanation,
           compound = CENTER,
           fg="blue", padx=0,font="ComicSansMS 32 bold")
w2.pack(side='left')

PhotoImage没有显示与之关联的图像
