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，

user.rc

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

function.cpp

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

的main.cpp

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

此代码效果很好，仅当用户选择单个键并且在选择多个键组合时不工作，如CTRL + F8。

Answer 1

您需要将虚拟密钥与wHotKey值隔离开来：

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