IDXGIFactory1 interface

The IDXGIFactory1 interface implements methods for generating DXGI objects.

Methods

The IDXGIFactory1 interface has these methods.

Method Description
IDXGIFactory1::EnumAdapters1 Enumerates both adapters (video cards) with or without outputs.
IDXGIFactory1::IsCurrent Informs an application of the possible need to re-enumerate adapters.

Remarks

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);

Requirements

   
Minimum supported client Windows 7 [desktop apps | UWP apps]
Minimum supported server Windows Server 2008 R2 [desktop apps | UWP apps]
