IDXGIFactory1 interface (dxgi.h)
The IDXGIFactory1 interface implements methods for generating DXGI objects.
The IDXGIFactory1 interface inherits from IDXGIFactory. IDXGIFactory1 also has these types of members:
The IDXGIFactory1 interface has these methods.
Enumerates both adapters (video cards) with or without outputs.
Informs an application of the possible need to re-enumerate adapters.
This interface is not supported by DXGI 1.0, which shipped in Windows Vista and Windows Server 2008. DXGI 1.1 support is required, which is available on Windows 7, Windows Server 2008 R2, and as an update to Windows Vista with Service Pack 2 (SP2) (KB 971644) and Windows Server 2008 (KB 971512).
To create a factory, call the CreateDXGIFactory1 function.
Because you can create a Direct3D device without creating a swap chain, you might need to retrieve the factory that is used to create the device in order to create a swap chain. You can request the IDXGIDevice or IDXGIDevice1 interface from the Direct3D device and then use the IDXGIObject::GetParent method to locate the factory. The following code shows how.
IDXGIDevice1 * pDXGIDevice; hr = g_pd3dDevice->QueryInterface(__uuidof(IDXGIDevice1), (void **)&pDXGIDevice); IDXGIAdapter * pDXGIAdapter; hr = pDXGIDevice->GetParent(__uuidof(IDXGIAdapter), (void **)&pDXGIAdapter); IDXGIFactory1 * pIDXGIFactory; pDXGIAdapter->GetParent(__uuidof(IDXGIFactory1), (void **)&pIDXGIFactory);
