问题描述
我试图在我的图像背景上的某个位置放置两个图像按钮,但我的按钮没有出现.我认为他们的图像在背景后面.
I am trying to place two image buttons on my image background in a certain position, but my buttons are not appearing. I think their images are behind the background.
我尝试使用 place
和 pack
,两者都不起作用.可能是什么问题?
I tried to use place
and pack
, both did not work. What could be the problem?
from tkinter import*
import tkinter as tk
import settings
class Application(Frame):
def __init__ (self, master):
Frame.__init__(self,master)
self.grid()
self.create_widgets()
def create_widgets(self):
button1 = PhotoImage(file ="button1.gif")
button2 = PhotoImage(file ="button2.gif")
settings_button = Button(self, image = button1,
command = self.mult_command, width = 15)
settings_button.place(x=1, y=1)
rules_button = Button(self, image = button2,
command = self.the_rules, width = 15)
rules_button.place(x=50, y=50)
def main_code():
window = Tk()
window.title("The Bouncer")
bg_image = PhotoImage(file ="pic.gif")
x = Label (image = bg_image)
x.image = bg_image
x.place(x = 0, y = 0, relwidth=1, relheight=1)
window.geometry("600x300")
app = Application(window)
window.mainloop()
main_code()
谢谢
推荐答案
很可能您的图像在显示之前就被垃圾回收了.这是一个常见的 Tkinter 问题.尝试更改行:
It is likely that your image is being garbage collected before it is displayed. This is a common Tkinter gotcha. Try changing the lines:
button1 = PhotoImage(file ="button1.gif")
button2 = PhotoImage(file ="button2.gif")
到
self.button1 = PhotoImage(file ="button1.gif")
self.button2 = PhotoImage(file ="button2.gif")
并使用
settings_button = Button(self, image = self.button1, command = self.mult_command, width = 15)
等
这应该保留对您的图像的引用,防止它被垃圾收集.
This should keep a reference to your image, stopping it from getting garbage collected.
