示例1:

void FSlateD3DRenderer::DrawWindows( FSlateDrawBuffer& InWindowDrawBuffer )
{
	// Update the font cache with new text before elements are batched
	FontCache->UpdateCache();

	// Iterate through each element list and set up an RHI window for it if needed
	TArray<FSlateWindowElementList>& WindowElementLists = InWindowDrawBuffer.GetWindowElementLists();
	for( int32 ListIndex = 0; ListIndex < WindowElementLists.Num(); ++ListIndex )
	{
		FSlateWindowElementList& ElementList = WindowElementLists[ListIndex];

		if ( ElementList.GetWindow().IsValid() )
		{
			TSharedRef<SWindow> WindowToDraw = ElementList.GetWindow().ToSharedRef();

			// Add all elements for this window to the element batcher
			ElementBatcher->AddElements( ElementList.GetDrawElements() );

			bool bUnused = false;
			ElementBatcher->FillBatchBuffers( ElementList, bUnused );

			// All elements for this window have been batched and rendering data updated
			ElementBatcher->ResetBatches();

			FVector2D WindowSize = WindowToDraw->GetSizeInScreen();

			FSlateD3DViewport* Viewport = WindowToViewportMap.Find( &WindowToDraw.Get() );
			check(Viewport);

			RenderingPolicy->UpdateBuffers( ElementList );

			check(Viewport);
			GD3DDeviceContext->RSSetViewports(1, &Viewport->ViewportInfo );

			ID3D11RenderTargetView* RTV = Viewport->RenderTargetView;
			ID3D11DepthStencilView* DSV = Viewport->DepthStencilView;

			GD3DDeviceContext->OMSetRenderTargets( 1, &RTV, NULL );

			RenderingPolicy->DrawElements( ViewMatrix*Viewport->ProjectionMatrix, ElementList.GetRenderBatches() );

			GD3DDeviceContext->OMSetRenderTargets(0, NULL, NULL);


			const bool bUseVSync = false;
			Viewport->D3DSwapChain->Present( bUseVSync ? 1 : 0, 0);

			// All elements have been drawn.  Reset all cached data
			ElementBatcher->ResetBatches();
		}

	}

	// flush the cache if needed
	FontCache->ConditionalFlushCache();
