winapi - Windows API Mousehook , Capture rightmousebutton + Ctrl (WM_RBUTTONDOWN + MK_CONTROL) 一起点击

Question

最初，当我按下鼠标右键时，我能够打印一些东西， 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键时打印一些东西。我怎样才能做到这一点？

我试过这个

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

当我想尝试只按下 Ctrl 并且它应该打印一些东西的情况时，它仍然不起作用

LRESULT CALLBACK MainWindow::mouseProc(int Code, WPARAM wParam, 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, Code, wParam, lParam);
}

我在这里想念什么？

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

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);
}

如果您想使用键盘挂钩仅挂钩“Ctrl”：

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

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

    return;
};
