Windows Forms中的DirectX9
Windows Forms中的DirectX9
提问于 2012-01-06 04:28:35
我需要在C++窗体中集成一个DirectX9设备--我该怎么做？
一方面，我拿到了我的DirectX申请……
HWND hWnd;
WNDCLASSEX wc;
ZeroMemory(&wc, sizeof(WNDCLASSEX));
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = WindowProc;
wc.hInstance = hInstance;
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.lpszClassName = "WindowClass";
RegisterClassEx(&wc);
hWnd = CreateWindowEx(NULL, "WindowClass", "Engine",
WS_OVERLAPPEDWINDOW, 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT,
NULL, NULL, hInstance, NULL);
ShowWindow(hWnd, nCmdShow);
m_D3D = Direct3DCreate9(D3D_SDK_VERSION);
D3DPRESENT_PARAMETERS d3dpp;
ZeroMemory(&d3dpp, sizeof(d3dpp));
d3dpp.Windowed = TRUE;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.hDeviceWindow = hWnd;
d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;
d3dpp.BackBufferWidth = SCREEN_WIDTH;
d3dpp.BackBufferHeight = SCREEN_HEIGHT;
d3dpp.EnableAutoDepthStencil = TRUE;
d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
// creates device
m_D3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_HARDWARE_VERTEXPROCESSING, &d3dpp, &m_Device);另一方面，我得到了我的Windows窗体
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
Application::Run(gcnew Form1());我如何合并它？

// do 3D rendering on the back buffer here
globals::d3ddev->EndScene(); // ends the 3D scene
globals::d3ddev->Present(NULL, NULL, NULL, NULL);
// displays the created frame

您可以在窗体的OnLoad()方法重写或加载事件处理程序中初始化DirectX代码。您将需要它的句柄属性：
protected:
void OnLoad(EventArgs^ e) override {
HWND hWnd = (HWND)(void*)this->Handle;
YourDirectXInitializeFunction(hWnd);
