Tkinter中按钮后面的图像(PhotoImage) [英] Image behind buttons in tkinter (PhotoImage)

问题描述

我一直在尝试添加图像，以使我的按钮位于图像的顶部，但是只能使图像完全覆盖所有内容，或者迫使图像位于按钮覆盖的水平部分下方. /p>

以下是相关代码:

class MainMenu(Frame):
    def __init__(self, master):
        Frame.__init__(self, master)
        self.master = master
        self.initUI()

    def initUI(self):
        self.master.title("Adventure")
        bg = PhotoImage(file="Background-gif.gif")

        newGameButton = Button(self, text="New Game", height=2, width=20, command=self.newGame)
        newGameButton.pack(side=TOP, pady=50)
        loadGameButton = Button(self, text="Load Game", height=2, width=20, command=self.loadGame)
        loadGameButton.pack(side=TOP)
        quitButton = Button(self, text="Quit", height=2, width=20, command=self.close)
        quitButton.pack(side=TOP, pady=50)

        label = Label(self, image=bg)
        label.image = bg
        label.pack(fill=BOTH, expand=1)

        self.pack()

非常感谢.

解决方案

您可以将图像放置在画布上，然后放置一个画布上的按钮:

import Tkinter as tk
import ImageTk

FILENAME = 'image.png'
root = tk.Tk()
canvas = tk.Canvas(root, width=250, height=250)
canvas.pack()
tk_img = ImageTk.PhotoImage(file = FILENAME)
canvas.create_image(125, 125, image=tk_img)
quit_button = tk.Button(root, text = "Quit", command = root.quit, anchor = 'w',
                    width = 10, activebackground = "#33B5E5")
quit_button_window = canvas.create_window(10, 10, anchor='nw', window=quit_button)    
root.mainloop()

I've been trying to add an image so that my buttons sit on top of the image, but have only been able to make the image cover everything completely or force the image to be underneath the horizontal part the buttons cover.

Here is the relevant code for it:

class MainMenu(Frame):
    def __init__(self, master):
        Frame.__init__(self, master)
        self.master = master
        self.initUI()

    def initUI(self):
        self.master.title("Adventure")
        bg = PhotoImage(file="Background-gif.gif")

        newGameButton = Button(self, text="New Game", height=2, width=20, command=self.newGame)
        newGameButton.pack(side=TOP, pady=50)
        loadGameButton = Button(self, text="Load Game", height=2, width=20, command=self.loadGame)
        loadGameButton.pack(side=TOP)
        quitButton = Button(self, text="Quit", height=2, width=20, command=self.close)
        quitButton.pack(side=TOP, pady=50)

        label = Label(self, image=bg)
        label.image = bg
        label.pack(fill=BOTH, expand=1)

        self.pack()

Many thanks.

解决方案

You could place an image on a canvas, and then place a button on the canvas:

import Tkinter as tk
import ImageTk

FILENAME = 'image.png'
root = tk.Tk()
canvas = tk.Canvas(root, width=250, height=250)
canvas.pack()
tk_img = ImageTk.PhotoImage(file = FILENAME)
canvas.create_image(125, 125, image=tk_img)
quit_button = tk.Button(root, text = "Quit", command = root.quit, anchor = 'w',
                    width = 10, activebackground = "#33B5E5")
quit_button_window = canvas.create_window(10, 10, anchor='nw', window=quit_button)    
root.mainloop()
