自定义全局热键

Question

我正在尝试为我的应用程序获取用户定义的全局热键。这是我的应用程序代码，

用户.rc

CONTROL         "", IDC_MHOTKEY, HOTKEY_CLASS, WS_TABSTOP, 91, 86, 68, 14

函数.cpp

    WORD wHotKey = SendDlgItemMessage(hwnd, IDC_MHOTKEY, HKM_GETHOTKEY, 0, 0);
    GLOBAL_HOTKEY= wHotKey;
    RegisterHotKey ( NULL, TURN_OFF_HOTKEY, HIBYTE(LOWORD(wHotKey)) , wHotKey);

main.cpp

   if ( messages.message == WM_HOTKEY && ( HIWORD ( messages.lParam ) == GLOBAL_HOTKEY) )
                        alert("Coming only for Single Key");

此代码运行良好，仅当用户选择单个键并且在选择多个组合键(如 CTRL+F8)时不起作用。

Answer 1

您需要将虚拟键从 wHotKey 值中分离出来:

RegisterHotKey ( NULL, 
    TURN_OFF_HOTKEY,  
    HIBYTE(LOWORD(wHotKey)),          // Modifiers
    LOBYTE(LOWORD(wHotKey))           // Virtual key
);
