切换键盘布局

该功能封装成了一个装饰器，函数执行完恢复了原键盘布局

from win32con import WM_INPUTLANGCHANGEREQUEST

import win32api
def setKeyboardLayout_en(inner):
 def wrapper(*args, **kwargs):
 if win32api.LoadKeyboardLayout('0x0409', win32con.KLF_ACTIVATE) == None:
 return Exception('加载键盘失败')

 LID = {0x0804: "Chinese (Simplified) (People's Republic of China)",
 0x0409: 'English (United States)'}

 # 获取前景窗口句柄
 hwnd = win32gui.GetForegroundWindow()

 # 获取前景窗口标题
 title = win32gui.GetWindowText(hwnd)
 # 获取键盘布局列表
 im_list = win32api.GetKeyboardLayoutList()
 im_list = list(map(hex, im_list))
 print(im_list)
 oldKey = hex(win32api.GetKeyboardLayout())

 # 设置键盘布局为英文
 result = win32api.SendMessage(
 hwnd,
 WM_INPUTLANGCHANGEREQUEST,
 0,
 0x4090409)
 if result == 0:
 print('设置英文键盘成功！')
 inner(*args,*kwargs)
 result = win32api.SendMessage(
 hwnd,

 oldKey)
 if result == 0:
 print('还原键盘成功！')
 return wrapper
