如何使用键盘 shortcut/binding 激活 tkinter 菜单和工具栏?

How to activate tkinter menu and toolbar with keyboard shortcut/binding?

我在 tkinter 中有一个文件菜单,当我点击它时,一个文件菜单打开。我还希望菜单使用键盘快捷键打开,例如“alt+f”,而不是单击它。

代码如下:

def Open_FileMenu_With_KeyboardShortcut():
    pass
    # How would I make the file menu appear when I click "Alt+f"
root.bind("<the code for alt-f>", Open_FileMenu_With_KeyboardShortcut)

# File Option for Menu Bar 
FileOption = Menu(MenuBar, tearoff=False)
MenuBar.add_cascade(label="File", menu=FileOption, underline=0)
FileOption.config(bg="White", fg="Black", activebackground="Whitesmoke", activeforeground="Black", activeborderwidth=1, font=('Monaco', 11))
# New Option for File Option
NewMenu = Menu(FileOption, tearoff=False)
NewMenu.config(bg="White", fg="Black", activebackground="Whitesmoke", activeforeground="Black", activeborderwidth=1, font=('Monaco', 11))
NewMenu.add_command(label="New File", command=NewFile)
NewMenu.add_command(label="From Template", command=None)
# Cascade the New menu to the File Menu
FileOption.add_cascade(label="New", menu=NewMenu)
# The remaining settings options
FileOption.add_command(label="Open File", command=OpenFile, accelerator="Ctrl+O")
FileOption.add_command(label="Open Folder", command=None, accelerator="Ctrl+Shift+O")  
FileOption.add_command(label="Open Recent", command=None)
FileOption.add_separator()
FileOption.add_command(label="Save File", command=SaveFile, accelerator="Ctrl+S")
FileOption.add_command(label="Save As", command=SaveFileAs, accelerator="Ctrl+Shift+S")
FileOption.add_separator()
FileOption.add_command(label="Revert File", commmand=None)
FileOption.add_command(label="Close Editor", command=None, accelerator="Ctrl+W")
FileOption.add_separator()
FileOption.add_command(label="Quit", command=QuitApplication, accelerator="Ctrl+q")

如何使用键盘快捷键打开文件菜单?

我不是 100% 确定问题在问什么,但根据我对问题的理解,这应该有效:

import tkinter as tk

root = tk.Tk()

MenuBar = tk.Menu(root, tearoff=False) # Create the main menu
root.config(menu=MenuBar) # Assign it to the root

# File Option for Menu Bar 
FileOption = tk.Menu(MenuBar, tearoff=False)
MenuBar.add_cascade(label="File", menu=FileOption, underline=0)
...
FileOption.add_command(label="Quit", command=exit, accelerator="Ctrl+q")

同时按下 Altf 将打开文件菜单。

将命令绑定到 root 时,您只需要 以及您要使用的键,在您的例子中是 f.

root.bind("<Alt-key-f>", Open_FileMenu_With_KeyboardShortcut)
