Tkinter下拉菜单具有键盘快捷键吗? [英] Tkinter dropdown Menu with keyboard shortcuts?

问题描述

我想在Tkinter中有一个下拉菜单，其中包含与此命令相关联的快捷键.这可能吗?

I would like to have a Dropdown Menu in Tkinter, that includes the shortcut key associated with this command. Is this possible?

我还要如何在某个字符下添加下划线，以允许Alt-F-S(文件->保存)?

How would I also add the underline under a certain character, to allow for Alt-F-S (File->Save)?

推荐答案

import tkinter as tk
import sys

class App(tk.Tk):

    def __init__(self):
        tk.Tk.__init__(self)
        menubar = tk.Menu(self)
        fileMenu = tk.Menu(menubar, tearoff=False)
        menubar.add_cascade(label="File", underline=0, menu=fileMenu)
        fileMenu.add_command(label="Exit", underline=1,
                             command=quit, accelerator="Ctrl+Q")
        self.config(menu=menubar)

        self.bind_all("<Control-q>", self.quit)

    def quit(self, event):
        print("quitting...")
        sys.exit(0)

if __name__ == "__main__":
    app = App()
    app.mainloop()
