Question

当我单击“ Hamstring”按钮时，应该显示选项菜单，并且应该禁用该按钮。当我单击“刷新”按钮时，选项菜单应该会消失，而“筋绳”按钮应回到其正常状态。

我需要它以这种方式工作，因为稍后我将有几个其他带有不同选项菜单的按钮

我可能没有正确编码我的函数。尝试了所有我知道并且可以找到的东西。任何帮助将不胜感激！

import tkinter as tk
from PIL import Image, ImageTk
import yoga_Images
import yogaposes

root = tk.Tk()

yoga_dict2 = {}
for yoga_name2 in yogaposes.hamstringposes:
    yoga_dict2[yoga_name2] = ImageTk.PhotoImage(Image.open("./yoga_Images/{}.png".format(yoga_name2)))

variable2 = tk.StringVar(root)
variable2.set(yogaposes.hamstringposes[0])

def change_image2(b):
    print(b)  # selected option
    my_image.config(image=yoga_dict2[b])

def onclickHamstring(args):
    if args == 1:
        opt2 = tk.OptionMenu(root, variable2, *yogaposes.hamstringposes, command=change_image2)
        opt2.config(width=50, font=('Helvetica', 12))
        opt2.pack(pady=10)
        if (ci2_k['state'] == tk.NORMAL):
            ci2_k['state'] = tk.DISABLED
        else:
            ci2_k['state'] = tk.NORMAL
        
ci2_k = tk.Button(root, text="Hamstring poses", command=lambda:onclickHamstring(1))
ci2_k .pack(side="left",pady=10)

def normalizebuttons():
    ci2_k['state'] = tk.NORMAL
    opt2.destroy()
    
normalizeyogabuttons = tk.Button(root, text="Refresh", command=normalizebuttons)
normalizeyogabuttons.pack(side="left",pady=10)

my_image = tk.Label(root)
my_image.pack(pady=10)

root.mainloop()

版本2：

import tkinter as tk

variable2.set(yogaposes.hamstringposes[0])

def change_image2(b):
    print(b)  # selected option
    my_image.config(image=yoga_dict2[b])
    
my_image = tk.Label(root)
my_image.grid(pady=20, row=1, column=1)

o = tk.OptionMenu(root, variable2, *yogaposes.hamstringposes, command=change_image2)
def optdrops():
    opt2 = o
    opt2.config(width=50, font=('Helvetica', 12))
    opt2.grid(pady=10, row=1, column=1, sticky='n')

def onclickHamstring(args):
    if args == 1:

            ci2_k['state'] = tk.DISABLED
        else:

    if args == 2:
        if (ci2_k['state'] == tk.DISABLED):
            ci2_k['state'] = tk.NORMAL
            optdrops()
        else:
            ci2_k['state'] = tk.DISABLED
        o.destroy()
        my_image.destroy()

        
ci2_k = tk.Button(root, text="Hamstring poses", command=lambda:[onclickHamstring(1), optdrops()])
ci2_k.grid(pady=10, row=0, column=1)

normalizeyogabuttons = tk.Button(root, text="Refresh", command=lambda:onclickHamstring(2))
normalizeyogabuttons.grid(pady=10, row=2, column=1)


root.mainloop()

如何在Tkinter中销毁Optionmenu？
