Question

当你看到标题时。我尝试了bind_all，但是在不关注对话框的情况下似乎无法正常工作。

import os
import sys
import ctypes
from ctypes import wintypes
import win32con

byref = ctypes.byref
user32 = ctypes.windll.user32

HOTKEYS = {
  1 : (win32con.VK_F3, win32con.MOD_CONTROL),
  2 : (win32con.VK_F4, win32con.MOD_CONTROL)
}

def handle_win_f3 ():
  os.startfile (os.environ['TEMP'])

def handle_win_f4 ():
  print 'hello'
  user32.PostQuitMessage (0)

HOTKEY_ACTIONS = {
  1 : handle_win_f3,
  2 : handle_win_f4
}

#
# RegisterHotKey takes:
#  Window handle for WM_HOTKEY messages (None = this thread)
#  arbitrary id unique within the thread
#  modifiers (MOD_SHIFT, MOD_ALT, MOD_CONTROL, MOD_WIN)
#  VK code (either ord ('x') or one of win32con.VK_*)
#
for id, (vk, modifiers) in HOTKEYS.items ():
  print "Registering id", id, "for key", vk
  if not user32.RegisterHotKey (None, id, modifiers, vk):
    print "Unable to register id", id

#
# Home-grown Windows message loop: does
#  just enough to handle the WM_HOTKEY
#  messages and pass everything else along.
#
try:
  msg = wintypes.MSG ()
  while user32.GetMessageA (byref (msg), None, 0, 0) != 0:
    if msg.message == win32con.WM_HOTKEY:
      action_to_take = HOTKEY_ACTIONS.get (msg.wParam)
      if action_to_take:
        action_to_take ()

    user32.TranslateMessage (byref (msg))
    user32.DispatchMessageA (byref (msg))

finally:
  for id in HOTKEYS.keys ():
    user32.UnregisterHotKey (None, id)

这是注册全局热键的代码，我只是想在我的对话框中使用它来切换显示，还是有其他功能？你能帮帮我吗？

如何在python中使用tkinter注册全局热键？
