Question

我正在创建一个按钮滑块，但是如果我对按钮使用.pack方法，它不会滑动按钮。

# imports

if __name__ == "__main__":
    root = tk.Tk()
    root.title("Procket")
    root.geometry("500x500")

    listbox = tk.Listbox(root)

    canvas = tk.Canvas(root, bg="white")
    scrollbar = tk.Scrollbar(root, orient=tk.VERTICAL, command=listbox.yview)
    scrollbar.pack(side=tk.RIGHT, fill=tk.Y)
    canvas.config(yscrollcommand=scrollbar.set)

    filename = filedialog.askopenfilename(
        initialdir="C:",
        title="Select file"
    )

    path = "my/path"
    for file in os.listdir(path):
        image = Image.open(path+file)
        photo = ImageTk.PhotoImage(image)
        button = tk.Button(root, text="фыв", image=photo)
        button.pack()

        listbox.insert(tk.END, button)

    listbox.pack()
    scrollbar.config(command=listbox.yview)

    root.mainloop()

我该如何欺骗这个？预先感谢。

如果你想在 tkinter 中制作滑动按钮，那么使用这个我希望你喜欢这个：-


import tkinter
from tkinter import *


def Slide_button(master, bg, slide_paddle_bg, sliding_ball_bg, x, y):
    slide_canvas = Canvas(master, width=80, height=40, bg=bg)

    indexer = 1

    def call_choose(event):  # this is main function for control
        nonlocal indexer
        global state
        if indexer == 1:
            on_slide()
            indexer += 1
            state_ret("on")
        elif indexer == 2:
            on_slide2()
            indexer -= 1
            state_ret("off")

    i = 20

    def on_slide():  # this function for animation right to left
        nonlocal i
        slide_button.place(x=i, y=13)
        i += 3
        if i < 50:
            master.after(1, on_slide)

    def on_slide2():  # this function for left to right
        nonlocal i
        slide_button.place(x=i, y=12)
        i -= 3
        if i > 17:
            master.after(1, on_slide2)

    def caller_for_slide_button():
        call_choose(0)

    slide_frame = Frame(slide_canvas, width=50, height=18, bg=slide_paddle_bg)
    slide_button = Button(slide_canvas, width=2, bg=sliding_ball_bg, command=caller_for_slide_button)
    slide_frame.bind("<Button-1>", call_choose)
    slide_button.place(x=20, y=12)
    slide_frame.place(x=20, y=16)
    slide_canvas.place(x=x, y=y)


root = tkinter.Tk()

Slide_button(root, "red", "cyan", "blue", 30, 30)


def state_ret(state):
    print(state)


root.mainloop()

如果你想在 tkinter 中制作一个滑动按钮，试试这个：

import tkinter
from tkinter import *

def Slide_button(master, bg, slide_paddle_bg, sliding_ball_bg, x, y, command):
    """
    :param master: give canvas frame root where you want to made slide button.
    :param bg: give background of slide button.
    :param slide_paddle_bg: give background of slide paddle in which button is slide.
    :param sliding_ball_bg: give background of button that is slide on paddle.
    :param x: give position x of slide button.
    :param y: give position x of slide button.
    :param command: give a function take state argument.
    :return: it not return any thing
    
    msg= the given function in command it is call by this function.
    """

    slide_canvas = Frame(master, width=80, height=40, bg=bg)

    indexer = 1
    def call_choose(event):  # this is main function for control
        nonlocal indexer
        if indexer == 1:
            on_slide()
            indexer += 1
            command(state="on")
        elif indexer == 2:
            on_slide2()
            indexer -= 1
            command(state="off")

    i = 20

    def on_slide():  # this function for animation right to left
        nonlocal i
        slide_button.place(x=i, y=13)
        i += 3
        if i < 50:
            master.after(1, on_slide)

    def on_slide2():  # this function for left to right
        nonlocal i
        slide_button.place(x=i, y=12)
        i -= 3
        if i > 17:
            master.after(1, on_slide2)

    def caller_for_slide_button():
        call_choose(0)

    slide_frame = Frame(slide_canvas, width=50, height=18, bg=slide_paddle_bg)
    slide_button = Button(slide_canvas, width=2, bg=sliding_ball_bg, command=caller_for_slide_button)
    slide_frame.bind("<Button-1>", call_choose)
    slide_button.place(x=20, y=12)
    slide_frame.place(x=20, y=16)
    slide_canvas.place(x=x, y=y)
