Tkinter Windows 上下文菜单中的快捷方式

Question

I a have a menu that I display as a context menu in a tkinter application:

rmenu = tk.Menu(None, tearoff=0, takefocus=0)
# add some commands here
rmenu.add_command(label="Copy", copyfunction, accelerator="Shift-C")
rmenu.bind("<Shift-KeyPress-C>", copyfunction)                       # this doesn't work on windows!

I define a shortcut for a command in this context menu, and then, when I try to run the command by typing <Shift> + <C> on windows it doesn't work. Actually, I get a beep.

Is there a way to define shortcut in this situation?

Update:

I have even tried to generate a event in the program using:

rmenu.event_generate("<Shift-KeyPress-C>", when="tail")

But the function copyfunction wasn't called.

PS: This works on Linux

Answer 1

bind the keyboard shortcut to the root . Only things with focus listen for key bindings. How often does the context menu have focus? By using bind_all on the root , whatever has focus will trigger the key binding.

root.bind_all("<Shift-C>", copyfunction)
