按住Windows API的Mousehook，捕获鼠标右键+ CtrlWM_RBUTTONDOWN + MK_CONTROL

如何解决按住Windows API的Mousehook，捕获鼠标右键+ CtrlWM_RBUTTONDOWN + MK_CONTROL

最初，当我只使用鼠标右键按下时，我能够打印某些内容 if (wParam == WM_RBUTTONDOWN)但现在，我想要相同的效果，我想在按下鼠标右键+ Ctrl 键时打印出一些东西。我该如何实现？

我尝试过

LRESULT CALLBACK MainWindow::mouseProc(int Code,WParaM wParam,LParaM lParam)
{
        auto& ms = *(const MsllHOOKSTRUCT*)lParam;
        MsllHOOKSTRUCT* pMouseStruct = (MsllHOOKSTRUCT*)lParam;
        if (pMouseStruct != nullptr)
        {
            if (wParam == WM_RBUTTONDOWN & MK_CONTROL)  // Here,i added MK_CONTROL but it doesn't work
            {
                qDebug() << "Print something when Right mouse button and Ctrl button is pressed togather"; 
            }
        }
    return CallNextHookEx(NULL,Code,wParam,lParam);
}

更新

当我想尝试仅按Ctrl键并应打印某些内容的情况时，它仍然不起作用

LRESULT CALLBACK MainWindow::mouseProc(int Code,LParaM lParam)
{
        auto& ms = *(const MsllHOOKSTRUCT*)lParam;
        MsllHOOKSTRUCT* pMouseStruct = (MsllHOOKSTRUCT*)lParam;
        if (pMouseStruct != nullptr)
        {
            if (wParam == MK_CONTROL)  // Here,i added only MK_CONTROL but it doesn't work
            {
                qDebug() << "Print something when  Ctrl button is pressed ";
            }
        }
    return CallNextHookEx(NULL,lParam);
}

我在这里想念什么？

解决方法

首先，如果要捕获右键+ ctrl，则可以在检测到WM_RBUTTONDOWN时检查Ctrl键的状态（是否按下）。

LRESULT CALLBACK mouseProc(int Code,WPARAM wParam,LPARAM lParam)
{
    auto& ms = *(const MSLLHOOKSTRUCT*)lParam;
    MSLLHOOKSTRUCT* pMouseStruct = (MSLLHOOKSTRUCT*)lParam;
    if (pMouseStruct != nullptr)
    {
        if (wParam == WM_RBUTTONDOWN && (GetAsyncKeyState(VK_LCONTROL)&0x8000))  //Left CONTROL key as example
        {
            std::cout << "ctrl + rbutton";
        }
    }
    return CallNextHookEx(NULL,Code,wParam,lParam);
}

如果您想使用键盘钩来钩住仅“ Ctrl”：

LRESULT CALLBACK keyboardProc(int Code,LPARAM lParam)
{
    KBDLLHOOKSTRUCT* pKeyboardStruct = (KBDLLHOOKSTRUCT*)lParam;
    if (pKeyboardStruct != nullptr)
    {
        if (pKeyboardStruct->vkCode == VK_LCONTROL)  
        {
            if(wParam == WM_KEYDOWN)
                std::cout << "  -ctrl-  ";
        }
    }
    return CallNextHookEx(NULL,lParam);
}
void main(void)
{
    HHOOK hmouse = SetWindowsHookEx(WH_MOUSE_LL,mouseProc,hInstance,0);
    HHOOK hkeyboard = SetWindowsHookEx(WH_KEYBOARD_LL,keyboardProc,0);

    MSG msg;
    while (GetMessage(&msg,0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    UnhookWindowsHookEx(hmouse);
    UnhookWindowsHookEx(hkeyboard);

    return;
};
