Question

当试图将鼠标移到菜单元素上时，我试图显示一个不同的光标，我认为要做到这一点，您必须在创建菜单时在选项上添加if (sound) sound = true; audio.play();选项。

var audio = document.getElementById("sound1");
$('#topleft').addClass('litTopLeft');

但是由于光标没有变化，我该怎么做？

Answer 1

tkinter Menu的{{3}}指出光标选项表示“ The cursor that appears when the mouse is over the choices, but only when the menu has been torn off ”。因此，我认为您实际上无法做到自己想要的。仅当子菜单已分离（撕下）时，您才能看到光标发生变化。这是一个演示。

import tkinter as tk

class Settings:
  def __init__(self, master):
    # Elements of the menu
    self.master=master
    self.menu = tk.Menu(root, fg="red")
    self.subMenu = tk.Menu(self.menu, cursor="plus")

  def openMenu(self):
    # Configuration of the menu
    self.menu.add_cascade(label="Options", menu=self.subMenu)
    self.addOptionsSubMenu()
    self.master.config(menu=self.menu)

  def addOptionsSubMenu(self):
    # Add elements at the sub menu
    self.subMenu.add_command(label="Quit", command=self.quit)
    self.subMenu.add_command(label="Do nothing", command=self.passa)

  # Quit the function
  def quit(self):
    exit()

  # Do nothing
  def passa(self):
    pass

root = tk.Tk()
app = Settings(root)
app.openMenu()
root.mainloop()
