如何在c++程序中创建快捷键(键盘输入，如'Alt‘或'Shift')

BOOL RegisterHotKey(
  HWND hWnd,
  int  id,
  UINT fsModifiers,
  UINT vk
);

MSG msg;
while (GetMessage(&msg, NULL, 0, 0))
{
    if (msg.message == WM_HOTKEY)
    {
        // 处理快捷键触发事件
        // ...
    }
    TranslateMessage(&msg);
    DispatchMessage(&msg);
}

#include <iostream>
#include <Windows.h>

#define HOTKEY_ID 1

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch (uMsg)
    {
    case WM_HOTKEY:
        if (wParam == HOTKEY_ID)
        {
            std::cout << "Shortcut key pressed!" << std::endl;
        }
        break;
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    default:
        return DefWindowProc(hwnd, uMsg, wParam, lParam);
    }
    return 0;
}

int main()
{
    // 注册窗口类
    WNDCLASS wc = {};
    wc.lpfnWndProc = WindowProc;
    wc.hInstance = GetModuleHandle(NULL);
    wc.lpszClassName = L"MyWindowClass";
    RegisterClass(&wc);

    // 创建窗口
    HWND hwnd = CreateWindowEx(
        0,
        L"MyWindowClass",
        L"Shortcut Key Example",
        0,
        0, 0, 640, 480,
        NULL,
        NULL,
        GetModuleHandle(NULL),
        NULL
    );

    // 注册快捷键
    BOOL result = RegisterHotKey(hwnd, HOTKEY_ID, MOD_ALT | MOD_SHIFT, 'K');
    if (!result)
    {
        std::cout << "Failed to register hotkey!" << std::endl;
        return 1;
    }

    // 消息循环
    MSG msg;
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    // 注销快捷键
    UnregisterHotKey(hwnd, HOTKEY_ID);

    return 0;
}
